What Is Physics for Kids?

Physics is, most simply put, the study of matter and energy and the interaction between the two .

Physics is like the rulebook of the universe. It helps us understand how everything around us works, from tiny atoms to the vastness of space. When we study physics, we learn about motion (like why things move), forces (like pushes and pulls), energy (what makes things happen), electricity, magnetism, and more. It’s like solving puzzles about how the world functions.

Kids can learn more about the world around them through fun physics experiments like the ones below and deep thinking!

80 of the Best Physics Projects for Clever Kids

February 21, 2020 by Ana Dziengel Leave a Comment

Physics projects are some of the most memorable science projects your kids will ever try. There, I said it even if you don’t believe it!

You see, physics is the branch of science that studies flying, launching, moving, and floating, as well as magnets, motors and electrical circuits, heat, light, and sound. Physics is fun! After you look over some of the projects in this collection I hope you’ll agree.

Now before we begin I want to address a common notion a lot of folks have about this branch of science: Physics is really hard! I completely understand this thought.

In fact the only class I ever almost failed in my entire academic career was physics. And I know why. Physics was presented to me as formulas about force, equilibrium, and momentum with not one single demonstration. Then I walked into a structural engineering class where we discussed the forces at work in designing buildings and my teacher told us he didn’t want us to open a book all quarter. Instead he told us to build models. He wanted us to experiment with how forces really interact in a structure by testing them in hands-on experiments. It was a profound experience for me and suddenly all the book learning “clicked.”

My goal with this collection of projects is to make physics more accessible and inviting to parents, teachers, and kids alike! But before we dive into the physics projects let’s get a bird’s eye view of what physics is all about!

What is the study of physics?

Physics is the branch of science that studies matter, how it moves and how it interacts. It is a HUGE topic and there is a lot of overlap with chemistry and biology. It’s really easy to hear the word physics and have your eyes glaze over, but in simple words physics is the study of how things move and interact with each other.

How do you explain physics to a child?

The best way to explain physics to kids is to skip an explanation and do a demonstration . Since physics encompasses the study of motion, light, electricity, magnetism, and aerodynamics, instead of trying to explain these concepts demonstrate them! I am a big believer in hands-on projects that give kids a chance to experience and experiment with a scientific concept rather than just hear or read about it. We all know an amazing project is memorable while a wordy explanation is forgettable. Kids are great visual learners so give them the chance to get excited about physics through projects!

What are main branches of Physics?

While I was assembling this post I realized scientists define the branches of physics in many different ways. The following is a list of the most commonly cited branches of physics compiled from both online and offline resources:

• Mechanics This includes force, motion, fluid and aerodynamics, and is the branch most people think of when they hear the word physics.
• Electromagnetism Electricity is physics!

Thermodynamics

• Sound and Waves
• Quantum Mechanics This is for the very serious! It’s the branch that studies atomic particles.

80+ Physics Projects for Kids

How to use this guide.

The physics projects for kids featured here are sorted by branches of physics and subcategories as follows (click on the topic to skip to that section) :

• Mechanics and Motion: Work & Energy, Newton’s Law’s of Motion, Radial Forces, Gravity, and Balance
• Electromagnetism & Electricity: Magnetism, Electricity

Optics & Sound

• Heat, Liquids, and Air: Thermodynamics, Hydrodynamics, & Aerodynamics

Some topics and categories were really easy to find great projects for (work and energy) some were more challenging (thermodynamics) and at least one impossible (Quantum mechanics, but that’s okay!). We tried to assemble as many as we could on this list!

Please note that many of these projects could fit in two or more categories as they demonstrate various principles and forces. I only classified them once on this list.

Mechanics and Motion

When most people think of physics they think about mechanics and motion. Mechanics refers to the motion of objects and motion is the position change of an object over time. Everything around us is constantly in motion. Even when we consider ourselves to be sitting still, the earth is rotating on its axis and moving around the sun.

Scientists have studied motion over the centuries and determined there are laws that can explain the motion of objects. These laws revolve around the idea of forces .

A force is something that pushes or pulls on an object to make it move. A force can make an object speed up (like kicking a ball) or or slow down (like friction) or hold an object in place (like gravity). Momentum is the force an object has based on its weight and motion. For a deeper look into forces go here .

In this section we’ll cover projects that focus on motion including 3 of the most famous laws of motion as outlined by Sir Isaac Newton.

Work and Energy Projects

Energy is defined as the ability to do work. Work refers to the amount of energy needed to move something over a distance using a force. The Law of Conservation of Energy states that energy is never created or destroyed it is simply changed from one state to another.

Potential Energy vs. Kinetic Energy

Two types of energy frequently disucssed in phyiscs are kinetic energy and potential energy. Kinetic energy is energy in motion. Potential energy is energy that is stored. An example of potential enrgy is a rubber band twisted up and held in place. Once the rubber band is released it unwinds quickly as kinetic energy.

Here are some projects that demonstrate work and energy:

Physics Project Idea: Rollback Can

Steam activity: stixplosions, how to build a catapult, transfer of energy science experiment, catapult stem project – diy catapult for kids, how to make a windmill model with a printable pattern, simple machines for kids: lego pulleys stem building challenge, power up your planes with a paper airplane launcher, featured work & energy videos:, newton's laws of motion.

Sir Isaac Newton was a mathematician and scientist who studied motion in the 1600's. He is credited with discovering the force of gravity as well as developing three laws of motion to describe how objects move. We'll look at each law of motion and some projects that highlight them below.

Newton's First Law of Motion is called the Law of Interia and states: An object at rest tends to stay as rest and an object in motion tends to stay in motion unless acted upon by an external force.

Newton's Second Law of Motio n states that the acceleration of an object depends on the force applied to the object and the object's mass. The relationship can be described with the following formula: F=ma

Force= Mass x Acceleration

Newton's Third Law of Motion states: For every action there is an equal and opposite reaction.

Here are some projects that focus on the laws of motion:

How To Make A Simple Newton's Cradle

Easy inertia science experiments with pennies, inertia zoom ball: super fun s.t.e.a.m. project, make a balloon pinwheel science demonstration, physics activities that explore newton's laws of motion, radial forces.

Kids love things that spin! There are several types of forces and movement that act upon objects as they spin:

Angular Momentum The momentum of an object rotating around a point.

Centripetal Force A force that pulls an object towards the center point, causing it to move in a circular path. The force is always orthogonal to the fixed center.

Centrifugal Force A force that pushes away from the center as an object is spinning. It's not a REAL force but an apparent force.

Friction is a force that slows down objects sliding against each other. It's the reason that spinning tops eventually slow down. If there was no friction on between the point on which a top spins and the surface on which it is spinning, it would spin forever!

Action Art: Spin Art Using a Bike

Diy spin art: art spinners from steam play & learn, simple paper toys: paper tops, homemade toy idea: diy skip-it, diy toys: spinning tops (+ magical disappearing colors), diy toy idea: spin-finite tops, gorgeous spin art hearts painting activity for kids, easy fidget spinner diy (free template) - science fair project idea, halloween science for kids: pumpkin spinning tops, stem toy: penny spinners, featured radial forces videos:.

Gravity is a force that attracts two bodies together. It's also the natural force that pulls everything towards the earth. The greater the mass of an object the more garvitational pull it has.

Scientists measure the acceration of gravity at the Earth's surface at 32 feet per second squared! That means the longer an object is free falling the more it's speed increases (not accounting for air resistance).

Here are some phyics projects for kids that explore the force of gravity and speed:

In phyiscs we use the word balance to describe a situation in which two forces are equal in magnitude and extered in opposite directions.

See saws and scales are two easy wasy to illustrate the concept of balance to kids. Here are some additonal project ideas:

How to Make a Balance Toy: Balance Hearts STEAM Activity

Diy balance toy & game, awesome earth day activity: make an earth balancer, how to make balance scales for toddlers and preschoolers, easy kid's craft: straw mobile, engineering for kids: twirling twig mobile, featured balance project videos, electromagnetism & electricity.

Did you know that electricity and magnetism are physics topics? Both of these “invisible” forces are some of kids’ favorites to explore through hands-on projects!

Magnetism describes a force that attracts or repels objects that are made of magnetic material.

A magnet is a type of material that attracts iron and produces it's own magnetic field. Magnets have a north and a south pole. If you hold two magnets close to each other and place like poles together the magnets will repel each other. If you place the opposite poles together they will quickly attract each other.

Electrical force is a force that causes electically charged bodies to either repel or attract. It's the force that carries electrical current through a wire. There are two types of electrical charges: positive and negative.

Similar to magentism like charges REPEL each other and opposite charges ATTRACT each other.

Here are some fun ways to explore elctriclty with kids.

What we see and hear is determined by physics! This includes the behavior of light waves and sounds waves, those that we can perceive and those we cannot.

Light is a type of energy made up of photons. Our eyes can perceive some of it and some forms we cannot perceive at all. Light travels in both wave form and particle form.

Photons are particles which can transmit light.

Optics is the study of light's behavior as well as tools we use to study and understand it, including how our eyes perceive it.

Physics also covers the study of heat and fluid dynamics which includes aerodynamics (the study of movement in air and gases) and hydrodynamics (the study of movement in liquids) .

Thermodynamics is the branch of physics that studies heat and heat transfer. When two obejcts of different temperatures come in contact, energy will transfer between them until they reach the same temperature and are in a state of equilibrium. Heat always transfers from the higher temperature to a lower temperature. You can read more about heat here.

Heat Sensitive Color Changing Slime

Kids science: flying tea bag hot air balloon, magic jumping coin trick, convection detection, inverted bottles, convection currents, featured thermodynamics videos, hydrodynamics.

Top 5 physics experiments you can do at home

October 17, 2022 By Emma Vanstone Leave a Comment

Physics is key to understanding the world around us. While some aspects may seem tricky to understand, many fundamental physics concepts can be broken down into simple concepts, some of which can be demonstrated using basic equipment at home.

This list of 5 physics experiments you can try at home is a great starting point for understanding physics and, hopefully a source of inspiration for little scientists everywhere!

Physics experiments you can do at home

1. archimedes and density.

The story behind Archimedes’ discovery of density is that he was asked by the King of Sicily to work out whether a goldsmith had replaced some gold from a crown with silver. Archimedes needed to determine if the goldsmith had cheated without damaging the crown.

The crown weighed the same as the gold the King had given the goldsmith, but gold is more dense than silver, so if there were silver in the crown its density would be less than if it were pure gold. Archimedes realised that if he could measure the crown’s volume, he could work out its density, but calculating the volume of a crown shape was a tough challenge. According to the story, Archimedes was having a bath one day when he realised the water level rose as he lowered himself into the bathtub. He realised that the volume of water displaced was equal to the volume of his body in the water.

Archimedes placed the crown in water to work out its density and realised the goldsmith had cheated the king!

Density Experiment

One fun way to demonstrate density is to make a density column. Choose a selection of liquids and place them in density order, from the most dense to the least dense. Carefully pour a small amount of each into a tall jar or glass, starting with the most dense. You should end up with a colourful stack of liquids!

2. Split light into the colours of the rainbow

Isaac Newton experimented with prisms and realised that light is made up of different colours ( the colours of the rainbow ). Newton made this discovery in the 1660s. It wasn’t until the 1900s that physicists discovered the electromagnetic spectrum , which includes light waves we can’t see, such as microwaves, x-ray waves, infrared and gamma rays.

How to split light

Splitting white light into the colours of the rainbow sounds tricky, but all you need is a prism. A prism is a transparent block shaped so light bends ( refracts ) as it passes through. Some colours bend more than others, so the whole spectrum of colours can be seen.

If you don’t have a prism, you can also use a garden hose! Stand with your back to the sun, and you’ll see a rainbow in the water! This is because drops of water act like a prism.

3. Speed of Falling Objects

Galileo’s falling objects.

Aristotle thought that heavy objects fell faster than lighter objects, a theory later disproved by Galileo .

It is said that Galileo dropped two cannonballs with different weights from the leaning tower of Pisa, which hit the ground at the same time. All objects accelerate at the same rate as they fall.

If you drop a feather and a hammer from the same height, the hammer will hit the ground first, but this is because of air resistance!

If a hammer and feather are dropped somewhere with no air resistance, they hit the ground simultaneously. Commander David Scott proved this was true on the Apollo 15 moonwalk!

Hammer and Feather Experiment on the Moon

Brian Cox also proved Galileo’s theory to be correct by doing the same experiment in a vacuum!

While you won’t be able to replicate a hammer or heavy ball and feather falling, you can investigate with two objects of the same size but different weights. This means the air resistance is the same for both objects, so the only difference is the weight.

Take two empty water bottles of the same size. Fill one to the top with water and leave the other empty. Drop them from the same height. Both will hit the ground at the same time!

4. Newton’s Laws of Motion

Sir Isaac Newton pops up a lot in any physics book as he came up with many of the laws that describe our universe and is undoubtedly one of the most famous scientists of all time. Newton’s Laws of Motion describe how things move and the relationship between a moving object and the forces acting on it.

Making and launching a mini rocket is a great way to learn about Newton’s Laws of Motion .

The rocket remains motionless unless a force acts on it ( Newton’s First Law ).

The acceleration of the rocket is affected by its mass. If you increase the mass of the rocket, its acceleration will be less than if it had less mass ( Newton’s Second Law ).

The equal and opposite reaction from the gas forcing the cork downwards propels the rocket upwards ( Newton’s Third Law ).

4. Pressure

Pressure is the force per unit area.

Imagine standing on a Lego brick. If you stand on a large brick, it will probably hurt. If you stand on a smaller brick with the same force it will hurt more as the pressure is greater!

Snowshoes are usually very wide. This is to reduce the pressure on the snow so it sinks less as people walk on it.

Pressure and Eggs

If you stand on one egg, it will most likely break. If you stand on lots of eggs with the same force, you increase the area the force is applied over and, therefore, reduce the pressure on each individual egg.

That’s five easy physics experiments you can do at home! Can you think of any more?

Physics Experiments For Kids [7 Awesome Ideas]

Physics experiments for kids are a perfect introduction to the fantastic world of science. Physics experiments challenge you to think about the hidden forces that drive the world. Even easy science experiments for kids can teach surprising lessons and reveal how fascinating the world is.

Here are a few fun physics projects you can try at home.

Physics Experiments for Kids

Powerful paper construction.

This is one of my favorite STEM activities. All you need is

• Scotch tape
• A stack of books/ one book and heavy items to balance on top of it

All great science experiments start with a question, ‘Can you use paper and tape to build a structure strong enough to support a book?’

I suggest posing the question and then seeing what your kids come up with. Trying and failing is part of a physics experiment.

When they’re ready, you can show them a solution. You roll the paper into a tube and use a small piece of tape to hold it in that shape. With four tubes, you can easily support an impressive number of books.

To extend the project, your kids can investigate which size and shape of the tube are the strongest. If your child is competitive, then why not make it a fun competition.

So Why Isn’t The Paper Crushed By The Books?

It’s all about the shape. A cylinder is one of the most robust shapes. Because it has a circular shape running all along the length, this evenly distributes the books’ weight. So no one point on the paper takes more stress and weakens.

Another illustration of this is with a soda can. You can try crushing a soda can — it’s really hard. An average can will support the weight of an average adult. But if you squash it a little in the middle, then try again, it suddenly crumples up. With its shape damaged, the weight is no longer evenly spread.

Lego Balloon Car/ Zipline

I’ve bundled these two physics experiments for kids together because they both use LEGO to explore some exciting physics ideas.

In both of these awesome physics experiments, your child has the chance to build their own creation and see how it performs. They can then tweak their design and process to improve the performance of what they’ve made. They can either make a balloon-powered car or build a ‘carrier’ to help a LEGO man ride a zipline.

There are so many ways that you can explore science, starting from these simple physics experiments. You can try to make the car travel further by changing either the vehicle or the balloon. You can find the perfect slope to get the LEGO man down the zipline as fast as possible, without his vehicle breaking at the end. You can measure the distances and times for older kids and calculate how fast their creations are going.

If you want to use these experiments to introduce some physics ideas, both of them touch on ideas of

• Potential and kinetic energy
• Friction and air resistance
• Speed, velocity, and acceleration
• Newton’s laws of motion

Fireproof Balloon

Have you ever been to a birthday party with a few too many balloons? If so, you might have noticed that if they get too near something warm, they pop. A great demonstration of this is with a balloon and a small candle. Blow up the balloon, hold it over the candle, and… pop!

In this simple physics experiment, you are going to make that balloon fireproof! Before you blow it up, you put some water in the balloon. Now when you bring the candle close… nothing happens. Just like magic, only better — science!

So What’s Going On?

First, let’s talk about why the balloon pops when it gets hot. The heat is transferred to the air molecules inside the balloon. They use that heat energy as kinetic energy, which means they start to move around faster. As the molecules spread out, they push harder on the balloon, until they push hard enough to break it.

So why does adding water help? It’s because water is amazing. Honestly, the science of water is fascinating. If it didn’t react to heat the way it does, we wouldn’t be here at all. Water is really good at absorbing heat. It takes a lot of heat energy to warm water up by even a small amount.

The heat from the candle gets absorbed by the water instead of the air molecules. The water needs over 4,000 times more energy to increase its temperature by a single degree than the air does. The same energy doesn’t do much to the water, and the temperature inside the balloon barely changes.

Using Gravity To Find A Cooked Egg

This incredibly simple physics experiment is just the sort that I love. It looks like magic from a distance, and if you’re the dramatic sort, you can play it that way to get your kids interested.

All you need to do is boil an egg in advance and then pop it in the fridge to cool. If you want to pretend you have magic powers, you should boil two to reveal the trick afterward. Present your kids with a row of identical eggs and ask if they can find the cooked one, without breaking any eggs.

The trick is to spin them. Cooked eggs spin much better than raw ones.

This teaches a critical lesson about physics. It shows how you can use science to uncover information that you can find out just from looking. Physics lets you ‘peek’ inside to find out what’s going on.

Extending The Idea

Here’s another experiment that explores the same idea. You need a long stick, around 1m is perfect, and a piece of clay. Put a fist-sized piece of clay around the stick. The clay should be towards one end of the stick, about 20 cm away from the end is perfect. Then try and balance the stick vertically on the palm of your hand.

The position of the clay makes a huge difference. When the clay is near the top, the stick rotates more slowly, making it easier for you to keep it balanced. It’s all about the position of the center of gravity.

Floating/Sinking Oranges

When it comes to simple physics experiments, it doesn’t get much simpler than this. All you need is:

• A bowl of water.

This is perfect if your kids have recently been doing science experiments about sinking and floating.

Ask your kids if they think an orange will sink or float. Then try it to see. So, it floats, not that exciting. But, what if you peel the orange, will that make a difference? Make sure to ask your kids to explain their reasoning.

If they have been learning about sinking and floating, they will likely say that it will still float, or it will float higher because you’re making it lighter. Which is why they’ll, hopefully, be amazed to find that without its peel, your orange sinks.

The question is, why?

Why do ‘Lighter’ Oranges Sink?

This is all about density. The peel of an orange is full of air pockets; they help protect it when it falls to the ground. They also reduce the density. When you take the peel off, it’s like taking off the orange’s life vest.

When it comes to a list of physics experiments for kids, it’s hard not to include catapults . After all, what child doesn’t like the idea of launching things into the air?

You can build catapults out of loads of household objects. The easiest to get hold of is popsicle sticks for the frame, a rubber band for the elastic energy store, a bottle cap to hold the projectile, and some glue to hold it all together. I recommend cotton balls or ping pong balls for a projectile — something that won’t hurt too much if someone’s aim is wandering.

There are so many physics ideas to explore inside these constructions, and so many variations to try. If your kids really enjoy this, you can try other similar science experiments to extend the ideas. For instance, you can learn about Trebuchets and try to build one of those instead.

Blowing Water Up A Straw

Here what you need to try this science experiment:

• Shallow bowl/saucer of water

The challenge – Can you lift the water out of the saucer, using the straw without sucking?

So how do you do it? You need to cut a small 3cm section off the end of your straw. You’ll then use your tape to stick the little piece back on. Except when you stick it back on, it should now be at 90 degrees to the rest of the straw. It should have one edge touching the rest of the straw. If it looks like a capital L, you’ve got it right.

Then you put the short end of the straw in the water and blow through the long end. If it doesn’t work, blow a bit harder!

What’s Going On?

When you blow, it creates an area of low pressure at the top of the small straw. Because the air pressure over the saucer is now higher, it pushes the water up the straw.

Frequently Asked Questions

How do you teach kids physics.

Physics is a way of looking at the world. It’s learning to ask questions about how and why things happen the way they do. So, a great way to teach kids about physics is to encourage them to ask questions.

When you see something interesting, ask them why they think it happened. Physics, like all of science, is about curiosity and creativity. The best way to help your child learn about physics is to ask questions, try and think of answers together, and then test your ideas.

Isn’t physics really hard?

A lot of adults think that science and physics especially are hard. A lot of that is to do with how it was taught. If you learned physics by memorizing equations and rote learning, it would always seem complicated and boring.

But, the basic ideas of physics aren’t that hard to understand, even for kids. Simple physics experiments are a great tool to help kids love physics. When you love learning about a topic, it doesn’t seem so hard.

Why should kids learn physics?

Physics is amazing to learn about because it is behind everything in the world. Without an understanding of physics, we’d be stuck in the dark ages.

It’s really easy to take all our modern technology for granted. When you learn about physics, you discover how amazing it really is. For instance, did you know that your phone relies on quantum physics to work?

Trying out physics projects at home is a fantastic way to get kids interested in learning more about the world around them.

50+ Physics Project Ideas

Physics is a branch of science that mainly deals with the study of the phenomena naturally existing in the universe. To get a better understanding of the laws of nature, physicists keep themselves regularly engaged in various experiments. Interestingly, there are certain experiments and activities that one can perform easily at home to verify the existence and righteousness of various laws of the universe. Some of the basic physics project ideas are given below:

1. Balloon Car

A balloon car is one of the simplest physics project that one can make at home with the help of easily available objects. The main items required to make a balloon car include one plastic bottle, two straws, four bottle caps, one balloon, and glue. First of all, place the bottle horizontally on the table and make two pairs of grooves on the curved surface of the bottle near the opening and the base. Cut a straw in half, insert both the straw pieces into the pair of grooves. Attach four bottle caps to the ends of the straws with the help of glue. Make a grooving on the top of the plastic bottle and fix a straw in the hole in such a way that a portion of straw is present on the top, while the rest part of the straw lies inside the bottle. Attach an inflated balloon to the end of the straw that is present on the top of the bottle. When the air escaping the balloon creates air pressure on the surface, the structure tends to move forward. From this particular project, one can easily learn about air pressure, state of the matter, rotatory motion, linear motion, conversion of motion from one form to another, and various other physical parameters.

Balloon Car

2. Catapult

A catapult is yet another simple project that one can easily make at home. To make a catapult, you need ice cream sticks, rubber bands, a bottle cap, and glue. First of all, build a stack of five ice cream sticks. Tie a rubber band on each end of the stack. Make sure that the rubber bands are properly tied and the sticks do not move. Now, take two more ice cream sticks. Place one of them on the top of the other to form a stack and attach a rubber band on one side of the stack. Slide the stack of five ice cream sticks between the stack of two ice-cream sticks. Wrap rubber band on the intersection point of the stacks to hold the catapult in place. Fix a bottle cap on the top stick with the help of glue. The catapult is ready. Place the projectile in the bottle cap, slightly push the topmost stick downwards, aim for the target, and release. It provides the user with the opportunity to learn about elasticity, tension, action-reaction force, projectile motion, and various other phenomena existing in nature.

3. Homemade Rocket

To make a homemade rocket physics project, you need an empty plastic bottle, vinegar, baking soda, three pencils, tape, a pair of scissors, and a cork. To make the structure of the rocket, attach the three pencils to the curved portion of the bottle near the top part. Make sure the pencils are placed at equal distances from each other in such a way that when the bottle is placed upside down on the ground, the mouth of the bottle does not touch the floor. The pencils should provide a rigid and stable launching pad for the model rocket. Pour some vinegar into the empty plastic bottle then add baking soda powder to it with the help of a funnel. Quickly use the cork to seal the bottle tight. Place the model rocket on the ground, move away, and observe the launch. This project helps the user understand the basic kinematics of a rocket, the chemical reaction of baking soda and vinegar, and the projectile motion of objects.

Homemade Rocket

4. Baking Soda Volcano

Displaying the volcanic eruption with the help of baking soda is a popular science experiment that involves a simple set of steps. To make a baking soda volcano at home, you require dish soap, water, food colouring, white vinegar, baking soda, and a plastic bottle. First of all, make the baking soda slurry by properly mixing a portion of baking soda with an equal part of water. Now, add water, vinegar, dish soap, and a few drops of food colouring into the plastic bottle. Pour the baking soda slurry into the bottle containing the mixture. Move a few steps back and observe the volcanic eruption from a distance. The chemical eruption occurs due to a chemical reaction between the vinegar and baking soda that produces carbon dioxide gas. Carbon dioxide gas tends to spread in the surroundings because it is comparatively heavy than the other gases present in the atmosphere; however, due to the confined area of the plastic bottle, it tends to cause an eruption.

Baking Soda Volcano

5. Fountain

To make a fountain as a physics project, you require plastic containers, wooden blocks, vinyl tubing, water pump, power supply, drill machine, pebbles, stones, miniature plants, cutter, and glue. Form the base of the fountain as per your choice with the help of wooden blocks. Drill a hole at the base of one of the plastic containers and another hole on the side of the other plastic container. Pass the vinyl tubing through both holes. Glue the tube around the joints and holes. Place the containers into the wooden structure of the fountain in such a way that one of the containers is present at a height more as compared to the other container. Make a hole on the front side of the container present above the base container. Attach a small water pump at the end of the tube and connect it to the power supply. Decorate the structure with the help of pebbles, stones, paint, miniature plants, etc. Pour water into the containers and observe the water flowing just like a fountain in a miniature pond. This project would help the users understand the flow of fluids, the working of a water pump, potential energy, and kinetic energy.

6. Newton’s Cradle

Newton’s cradle is one of the most interesting structures that demonstrate the law of conservation of energy and momentum in the easiest way. To make Newton’s cradle at home for your physics project, you need ice cream sticks, a glue stick or glue gun, marbles, string, a pair of scissors, tape, and a pencil. Glue eight ice cream sticks end to end and form two separate square-shaped structures. Attach these two squares to each other with the help of four ice cream sticks in such a way that the resultant structure is shaped like a cube. Cut the string into eight equal-length pieces. Keep the length of each string approximately equal to 8 inches. Attach marbles to the centre of each piece of the string with the help of glue or a hot glue gun. Mark 6 equally spaced points on the top two parallel ice cream sticks of the cube. Place the ends of the strings on the marks and apply tape on them. Allow the marbles to hang in between. Newton cradle physics project is ready to demonstrate momentum and prove the existence of the law of conservation of energy in real life.

Newton’s Cradle

7. Balancing Scale 

A balancing scale is a prominent physics project that is capable of demonstrating weight, gravity, equilibrium, and various other concepts. To make a traditional weighing scale at home, one would need two identical paper plates, string, pencil, tape, glue, a pair of scissors, and a cloth hanger. Punch three holes in both the paper plates. Make sure the holes are close to the outer boundary of the plates. Cut out six pieces of string that are equal in length. The length of each string should be approximately equal to 2 ft. Attach one end of each string to the individual holes punched in the plates. Hold one of the paper plates and take the three strings attached to the holes grooved into it. Properly stretch the strings and tie them together in a single knot. Perform the same procedure with the other plate. Carefully, hang the paper plates on each side of a cloth hanger. Hold the cloth hanger from the hook and begin weighing the objects.

Balancing scale

8. Periscope

A periscope is a device that is used by submarine operators to see the objects above the water surface. To construct a periscope at home, you require two congruent pieces of mirror, cardboard or a PVC pipe, cutter, tape or glue. Use cardboard to make three hollow cuboids and arrange them in the shape of a real periscope. Attach the mirror glasses to the opposite corners of the structure at an angle equal to 45°. Hold one end of the periscope on eye level and look at the distant objects easily. This would help the user understand the working of mirrors and the laws of reflection.

9. Visual Doppler 

To construct a model that displays the doppler effect in real life, you require two craft papers, a ruler, a pair of scissors, tape or glue, a small toy car, blank paper and pencil or a camera. Firstly, cut out a few five-inch wide strips from the craft paper. The length of the strips should be maintained in such a way that each strip is one inch shorter than the previous one. Tape or glue the ends of the strips together to form loops. Put a toy car in the middle of the second craft paper and arrange the loops around the car in a manner that the loops do not touch each other or the car. Make sure the distance between the loops is the same. Here, the loops represent the sound waves. Take a picture of the arrangement of loops around the car when it is standing still. In case you do not have a camera, draw the impression of the arrangement of loops around the car on blank paper with the help of a pencil. Roll the toy car gently in the forward direction until it touches the loops and pushes them together. The loops present in the front get squished together and demonstrate the high pitch sound, whereas the loops at the back get spread out and tend to display the low pitch sound. Record the position of the loops after the movement of the car with the help of a camera or by drawing an impression of the scene on a blank sheet. This experiment and physical model effectively demonstrates the concept of the Doppler effect, compression, rarefaction, and the nature of sound waves.

Visual Doppler

10. Electric Motor 

An electric motor is yet another simple physics project that one can easily build at home. To make a fully functional electric motor, you require a battery, a small piece of magnet, electric wire, two paper clips, electric tape, and a knife. First of all, wrap the electrical wire around a cylindrical object such as a battery about ten to twelve times to form a loop. Now, grab the ends of the wire and tie them across the loop of the wire. Remove the insulation from the ends of the wire. Take two paper clips and stretch one end of each clip. Attach the flat end of the clips to the positive and negative terminals of the battery with the help of electrical tape. Place the loop of wire between the curved ends of the paper clips. The final step is to place the magnet under the loop of the electrical wire. Tape the magnet on the battery to hold it in position. With the help of this particular project, the user would be able to have a better understanding of magnetism, conduction of current, rotatory motion, transfer and transformation of energy, etc.

Electric Motor

11. Compass

The equipment and materials necessary to build a drone include metal/plastic/wooden sheets, motors, propellers, battery, RC receiver, electronic speed control, zip ties, connecting wires, screws, screwdriver, solder wire, wire stripper, and soldering iron. First of all, design the frame of the quadcopter. Now, drill holes into the frame and assemble the motors. Make sure that the shaft of the motors is able to rotate freely. Connect the electronic speed controllers to the base of the drone. Use zip ties to make sure the electronic speed controllers are properly fixed to the frame and do not fall off during the flight. The landing of the quadcopter is an essential phase, hence the landing gear is required to be positioned appropriately. Assemble the controller on the top of the drone and connect it to the remote control. Test the flight and landing of the device. This project would certainly help the user learn about air resistance, uplift force, aerodynamics, remote control operation, and rotatory motion.

47. Earthquake Alarm 

The essential components required to build an earthquake alarm include a battery, battery cap, buzzer, safety pin, switch, cardboard sheet, nut and copper wire. The first step is to attach an inverted ‘L’ shaped cardboard cutout vertically in the middle of a cardboard sheet with the help of glue. Now, glue a safety pin in the middle of the ‘L’ shaped cardboard in a horizontal direction. Attach a nut to the end of a copper wire. Pass the wire through the loop of the safety pin and fix it on the top of the structure. Allow the nut to hang freely. Connect the buzzer to the switch, free end of the copper wire, and the battery clip. To test the working of the project, turn on the switch and lightly shake the structure. The buzzer starts to produce an alarming sound indicating the possibility of an earthquake. This project assists the person to learn about the reason behind the occurrence of an earthquake, seismic waves produced by the earth, seismometer, working of a buzzer, and connection of electronic components.

48. Water Dispenser 

To make a water dispenser at home, you require a cardboard box, glue gun, knife, plastic bottle, vinyl tubing, and a container. The first step is to drill a hole on the curved surface of the plastic bottle, a few inches above the base. Now, insert the vinyl tube into the hole. Place the bottle into the cardboard box. Poke a small hole on the front side of the cardboard box. Pass the pipe connected to the bottle through the hole made on the cardboard box. Place a container in front of the cardboard box under the pipe. Pinch the end of the pipe and pour the liquid into the bottle. Close the lid of the bottle. Twist the cap in a clockwise direction and observe that the liquid gets poured into the container. By making a water dispenser, the user would be able to understand the basics of pressure, the flow of liquids, and the Brownian motion of water molecules.

49. Propeller LED Pendulum Clock

A propeller LED pendulum clock is yet another common Arduino based project. One can easily build it with the help of electronic components such as LEDs, resistors, a transistor, Arduino Nano, IR receiver sensor, connecting wires, hall sensor, switch, capacitors, battery, USB cable, magnet, DC motor, printed circuit board, etc., and tools such as solder wire, soldering iron, wire clipper, and tongs. First of all, arrange all LEDs on the printed circuit board in a straight line and solder them in place. Connect resistors to the LEDs. Now, make the rest of the connections as per the circuit diagram. Solder the female header connectors onto the printed circuit board. Attach the Arduino nano board to the electronic circuit. The cathode terminal of the LEDs is connected to the ground terminal of the Arduino board. Make sure the cathode terminals of all of the LEDs are shorted. Connect the resistors to the 5V pin of the Arduino board. Make appropriate connections between resistors and the analogue/digital pins of the Arduino Nano board. Connect switch and battery to the circuit. Attach the IR receiver to the board and fix it in place with the help of solder wire. Attach the ground pin of the IR receiver to the ground of the circuit. Now, connect a 100-ohm resistor to the VCC pin of the IR receiver and a 100 microfarad capacitor between the VCC and ground pin of the sensor. Fix one end of a connecting wire to the output pin of the IR receiver sensor and the other end to the receiver pin of the Arduino Nano. Solder the hall sensor to the printed circuit board. Connect VCC pin, ground pin, and output pin of the Hall sensor to 5V pin, ground pin, and D2 pin of the Arduino Nano board. Verify the circuit connections according to the circuit diagram. Drill a hole in the middle of the printed circuit board and attach the motor in such a way that the motor shaft easily passes through the hole and the board is free to rotate. Add balancing weight to one end of the board. Attach the Arduino Nano board to a laptop or PC with the help of a USB cable and load the code. Turn on the switch and bring a piece of a magnet near the hall sensor. Observe that the LEDs begin to glow. Now, fix the circuit on a wooden structure that has a small magnet fixed on one side. Test the working of the project. This particular project would help the user know about hall sensor, IR sensor, conversion of energy from one form to another, magnetic field, programming, Arduino Nano, circuit connections, voltage, voltage drop, and various other concepts.

50. Data Transmission using Li-Fi

Li-Fi stands for Light fidelity. It is a technique that enables high-speed data transmission. To make a Li-Fi based data transmission system you require two broken pairs of wired earphones, wire stripper, solar panel, LED, resistor, battery clip, solder wire, soldering iron, and wire stripper. The first step is to cut and separate the connector of the earphones from the earbuds. Now, use a wire stripper to remove the insulation. You can observe that the earphone wire comprises four wires. One of the wires is the ground wire, while the rest three are for audio, right speaker, and left speaker. Clip the audio wire and join the speaker wires by twisting them together. Obtain two such arrangements. Connect the twisted wires to the positive terminal and the ground wire to the negative terminal of the solar panel. Take the other similar arrangement. Attach a battery clip to the speaker wire and a 220ohm resistor. Now, connect an LED between the ground wire and the free terminal of the resistor. Attach the battery to the battery clip. Insert the wire connected to the LED circuit into the earphone jack of a mobile phone and the wire connected to the solar panel to a speaker. Play a song on the mobile phone and observe the working of the circuit. This particular project helps the user learn about LI-FI technology and the transmission of data.

Data Transmission using Li-Fi

51. Ropeway Model

To make a ropeway model, the user requires a thick cardboard sheet, a pair of scissors, glue, tape, DC motors, and a rope or string. First of all cut four rectangle shape cardboard strips of equal dimensions. Attach a dc motor on one end of the rectangular strip. Cover the motor by forming a cuboid shape using cardboard around it. Form a closed electronic circuit by connecting a switch to the motor and a battery clip. Glue the switch and the battery on the top of the cuboid. Cut three circles out of the cardboard sheet, neatly stack them, and glue them together in place. Make sure that the circle present in the middle has a smaller diameter than the diameter of the two circles present on the boundary. Drill a hole in the middle of the three circles and fix it over the motor shaft. Make another cuboid box and circles with the help of cardboard having the same dimensions as the previous ones. Place both the cuboids opposite to each other and properly glue them in place. Make sure the height of the circles present on the top of the cuboids is the same. Wrap a string around the inner circle of both structures. The string should have a sufficient amount of tension in it. Attach two small cardboard boxes to the string and turn on the switch. The motor begins to rotate the shaft. The shaft transfers rotatory motion to the circular structure, which in turn causes the string to move. This particular project is helpful as it explains various physics-related concepts such as the working of a motor, transfer of momentum, inertia, rotary motion, and tension.

52. Hand Water Pump 

To make a hand water pump at home, you need a 60ml syringe, a 5ml syringe, copper tubes (5mm and 8mm), iron strips, foam valve for water pumps, bearing balls, iron nail, washer, plier, drill machine, cutter, nut bolts, and a plastic container. The first step is to remove the plunger from the syringe. Now, cut the foam valve in the shape of a circle that has a diameter equal to that of the barrel. Put the foam valve into the empty barrel of the syringe. Make sure that the valve is able to move up and down with ease. Now, remove the rubber part attached to the plunger and replace it with the valve. Now, drill two holes located opposite to each other on the top of the plunger rod. Cut the plunger into two halves. Take a copper rod and compress its ends with the help of a plier. Now, drill a small hole on one end of the copper rod and two holes on the other end of the rod. Attach the rod to the plunger by drilling holes and inserting nuts and bolts through the holes present on the copper rod and the plunger. Take a metal strip and wrap it around the curved surface of the syringe barrel. Leave a few inches on both the ends of the metal strip. Align the ends of the metal strip along a straight imaginary line and drill two holes through them. The next step is to take two pieces of metal strip, fold them along the length, and drill a hole at both ends of each metal strip. Use a grinder to curve the shape of the ends of the metal strips. Attach the curved metal strip to the surface of the syringe barrel and fix it in place with the help of nuts and bolts. Make a small hole in the top corner of the syringe barrel. Take a 5ml syringe and remove its plunger rod. Cut the front portion of the barrel and glue it over the hole made on the curved surface of the 60ml syringe barrel. Now, take another copper tube. Make a hole on the end of the tube and another hole a few inches away from the same end. Take the middle portion of the foam valve and cut it in such a way that you have two circles. Insert a washer in between both the circles and pass an iron nail through the arrangement. Place it into the 60ml syringe barrel. Now, insert the plunger that contains the foam valve and is connected to the iron rod into the 60ml syringe barrel. Drop a bearing over the plunger. Seal the top of the barrel with the help of a circular plastic cut out. Attach the two metal strips and the copper rods together with the help of nuts and bolts. Use another nut and bolt to fix the curved rectangle shape metal strip to the copper rod. Pour water into the plastic container and dip the hand pump into it. Fix the handpump over the lid of the container with the help of a hot glue gun. Test the working of the project. This particular project would help the user understand the fluid mechanics, pressure, positive displacement principle, kinetic energy, mechanical energy, movement of fluids from a region of high pressure to a region of low pressure, etc.

Hand Water Pump

53. Bubble Machine 

A bubble machine is yet another example of a simple physics project. To make a bubble machine at home, you require a plastic tube, a pair of scissors, plastic straws, a marker, tape, bottle cap, DC motors, battery, battery holder, propeller, USB, USB charger, electrical tape, and cardboard box. First of all, use a marker to make markings on the plastic tube. Make sure the markings are located at equal distances from each other. Now cut the tube along the marks to obtain congruent hollow cylindrical pieces. In a similar manner, cut the straws and obtain equal length hollow cylindrical pieces. Attach the straw pieces to each other in the shape of a star. Now, attach the plastic tube pieces to the end of the straw pieces arranged in the form of a star. Glue a bottle cap to the centre of the star-shaped pattern to form the bubble wheel. Take a DC motor and connect it to a battery holder. Fix the motor shaft to the bottle cap. The next step is to take a propeller and cut it into the desired size. Take another DC motor. Connect the motor to a USB charger. Attach the propeller to the motor shaft. Fix the motor on a cardboard box. Form the soap solution by dissolving shampoo, liquid dish wash, or liquid handwash into water. Pour this soap solution into a plastic container. Fix the motors on the lid of a plastic container. Make sure the motor connected to the plastic straw and tubes is fixed over the lid of the plastic container in such a way that the star pattern is properly immersed into the liquid present inside the container and is able to move easily. The propeller should be placed in such a way that the air circulated by the propeller directly passes through the plastic tube pieces. Check the motor connections and place an electrical tape over the joints. Turn on the power supply and test the working of the project. This helps the user understand the working of motors, propellers, circulation of air, surface tension, formation of bubbles, and the reason behind the tendency of the bubbles to maintain a spherical shape.

37 Cool Science Experiments for Kids to Do at Home

General Education

Are you looking for cool science experiments for kids at home or for class? We've got you covered! We've compiled a list of 37 of the best science experiments for kids that cover areas of science ranging from outer space to dinosaurs to chemical reactions. By doing these easy science experiments, kids will make their own blubber and see how polar bears stay warm, make a rain cloud in a jar to observe how weather changes, create a potato battery that'll really power a lightbulb, and more.

Below are 37 of the best science projects for kids to try. For each one we include a description of the experiment, which area(s) of science it teaches kids about, how difficult it is (easy/medium/hard), how messy it is (low/medium/high), and the materials you need to do the project. Note that experiments labelled "hard" are definitely still doable; they just require more materials or time than most of these other science experiments for kids.

#1: Insect Hotels

• Teaches Kids About: Zoology
• Difficulty Level: Medium
• Messiness Level: Medium

Insect hotels can be as simple (just a few sticks wrapped in a bundle) or as elaborate as you'd like, and they're a great way for kids to get creative making the hotel and then get rewarded by seeing who has moved into the home they built. After creating a hotel with hiding places for bugs, place it outside (near a garden is often a good spot), wait a few days, then check it to see who has occupied the "rooms." You can also use a bug ID book or app to try and identify the visitors.

• Materials Needed
• Shadow box or other box with multiple compartments
• Hot glue gun with glue
• Sticks, bark, small rocks, dried leaves, bits of yarn/wool, etc.

#2: DIY Lava Lamp

• Teaches Kids About: Chemical reactions
• Difficulty Level: Easy

In this quick and fun science experiment, kids will mix water, oil, food coloring, and antacid tablets to create their own (temporary) lava lamp . Oil and water don't mix easily, and the antacid tablets will cause the oil to form little globules that are dyed by the food coloring. Just add the ingredients together and you'll end up with a homemade lava lamp!

• Vegetable oil
• Food coloring
• Antacid tablets

#3: Magnetic Slime

• Teaches Kids About: Magnets
• Messiness Level: High (The slime is black and will slightly dye your fingers when you play with it, but it washes off easily.)

A step up from silly putty and Play-Doh, magnetic slime is fun to play with but also teaches kids about magnets and how they attract and repel each other. Some of the ingredients you aren't likely to have around the house, but they can all be purchased online. After mixing the ingredients together, you can use the neodymium magnet (regular magnets won't be strong enough) to make the magnetic slime move without touching it!

• Liquid starch
• Adhesive glue
• Iron oxide powder
• Neodymium (rare earth) magnet

#4: Baking Soda Volcanoes

• Teaches Kids About: Chemical reactions, earth science
• Difficulty Level: Easy-medium
• Messiness Level: High

Baking soda volcanoes are one of the classic science projects for kids, and they're also one of the most popular. It's hard to top the excitement of a volcano erupting inside your home. This experiment can also be as simple or in-depth as you like. For the eruption, all you need is baking soda and vinegar (dishwashing detergent adds some extra power to the eruption), but you can make the "volcano" as elaborate and lifelike as you wish.

• Baking soda
• Dishwashing detergent
• Large mason jar or soda bottle
• Playdough or aluminum foil to make the "volcano"
• Additional items to place around the volcano (optional)
• Food coloring (optional)

#5: Tornado in a Jar

• Teaches Kids About: Weather
• Messiness Level: Low

This is one of the quick and easy and science experiments for kids to teach them about weather. It only takes about five minutes and a few materials to set up, but once you have it ready you and your kids can create your own miniature tornado whose vortex you can see and the strength of which you can change depending on how quickly you swirl the jar.

• Glitter (optional)

#6: Colored Celery Experiment

• Teaches Kids About: Plants

This celery science experiment is another classic science experiment that parents and teachers like because it's easy to do and gives kids a great visual understanding of how transpiration works and how plants get water and nutrients. Just place celery stalks in cups of colored water, wait at least a day, and you'll see the celery leaves take on the color of the water. This happens because celery stalks (like other plants) contain small capillaries that they use to transport water and nutrients throughout the plant.

• Celery stalks (can also use white flowers or pale-colored cabbage)

#7: Rain Cloud in a Jar

This experiment teaches kids about weather and lets them learn how clouds form by making their own rain cloud . This is definitely a science project that requires adult supervision since it uses boiling water as one of the ingredients, but once you pour the water into a glass jar, the experiment is fast and easy, and you'll be rewarded with a little cloud forming in the jar due to condensation.

• Glass jar with a lid
• Boiling water
• Aerosol hairspray

#8: Edible Rock Candy

• Teaches Kids About: Crystal formation

It takes about a week for the crystals of this rock candy experiment to form, but once they have you'll be able to eat the results! After creating a sugar solution, you'll fill jars with it and dangle strings in them that'll slowly become covered with the crystals. This experiment involves heating and pouring boiling water, so adult supervision is necessary, once that step is complete, even very young kids will be excited to watch crystals slowly form.

• Large saucepan
• Clothespins
• String or small skewers
• Candy flavoring (optional)

#9: Water Xylophone

• Teaches Kids About: Sound waves

With just some basic materials you can create your own musical instrument to teach kids about sound waves. In this water xylophone experiment , you'll fill glass jars with varying levels of water. Once they're all lined up, kids can hit the sides with wooden sticks and see how the itch differs depending on how much water is in the jar (more water=lower pitch, less water=higher pitch). This is because sound waves travel differently depending on how full the jars are with water.

• Wooden sticks/skewers

#10: Blood Model in a Jar

• Teaches Kids About: Human biology

This blood model experiment is a great way to get kids to visual what their blood looks like and how complicated it really is. Each ingredient represents a different component of blood (plasma, platelets, red blood cells, etc.), so you just add a certain amount of each to the jar, swirl it around a bit, and you have a model of what your blood looks like.

• Empty jar or bottle
• Red cinnamon candies
• Marshmallows or dry white lima beans
• White sprinkles

#11: Potato Battery

• Teaches Kids About: Electricity
• Difficulty Level: Hard

Did you know that a simple potato can produce enough energy to keep a light bulb lit for over a month? You can create a simple potato battery to show kids. There are kits that provide all the necessary materials and how to set it up, but if you don't purchase one of these it can be a bit trickier to gather everything you need and assemble it correctly. Once it's set though, you'll have your own farm grown battery!

• Fresh potato
• Galvanized nail
• Copper coin

#12: Homemade Pulley

• Teaches Kids About: Simple machines

This science activity requires some materials you may not already have, but once you've gotten them, the homemade pulley takes only a few minutes to set up, and you can leave the pulley up for your kids to play with all year round. This pulley is best set up outside, but can also be done indoors.

• Clothesline
• 2 clothesline pulleys

#13: Light Refraction

• Teaches Kids About: Light

This light refraction experiment takes only a few minutes to set up and uses basic materials, but it's a great way to show kids how light travels. You'll draw two arrows on a sticky note, stick it to the wall, then fill a clear water bottle with water. As you move the water bottle in front of the arrows, the arrows will appear to change the direction they're pointing. This is because of the refraction that occurs when light passes through materials like water and plastic.

• Sticky note
• Transparent water bottle

#14: Nature Journaling

• Teaches Kids About: Ecology, scientific observation

A nature journal is a great way to encourage kids to be creative and really pay attention to what's going on around them. All you need is a blank journal (you can buy one or make your own) along with something to write with. Then just go outside and encourage your children to write or draw what they notice. This could include descriptions of animals they see, tracings of leaves, a drawing of a beautiful flower, etc. Encourage your kids to ask questions about what they observe (Why do birds need to build nests? Why is this flower so brightly colored?) and explain to them that scientists collect research by doing exactly what they're doing now.

• Blank journal or notebook
• Pens/pencils/crayons/markers
• Tape or glue for adding items to the journal

#15: DIY Solar Oven

• Teaches Kids About: Solar energy

This homemade solar oven definitely requires some adult help to set up, but after it's ready you'll have your own mini oven that uses energy from the sun to make s'mores or melt cheese on pizza. While the food is cooking, you can explain to kids how the oven uses the sun's rays to heat the food.

• Aluminum foil
• Knife or box cutter
• Permanent marker
• Plastic cling wrap
• Black construction paper

#16: Animal Blubber Simulation

• Teaches Kids About: Ecology, zoology

If your kids are curious about how animals like polar bears and seals stay warm in polar climates, you can go beyond just explaining it to them; you can actually have them make some of their own blubber and test it out. After you've filled up a large bowl with ice water and let it sit for a few minutes to get really cold, have your kids dip a bare hand in and see how many seconds they can last before their hand gets too cold. Next, coat one of their fingers in shortening and repeat the experiment. Your child will notice that, with the shortening acting like a protective layer of blubber, they don't feel the cold water nearly as much.

• Bowl of ice water

#17: Static Electricity Butterfly

This experiment is a great way for young kids to learn about static electricity, and it's more fun and visual than just having them rub balloons against their heads. First you'll create a butterfly, using thick paper (such as cardstock) for the body and tissue paper for the wings. Then, blow up the balloon, have the kids rub it against their head for a few seconds, then move the balloon to just above the butterfly's wings. The wings will move towards the balloon due to static electricity, and it'll look like the butterfly is flying.

• Tissue paper
• Thick paper
• Glue stick/glue

#18: Edible Double Helix

• Teaches Kids About: Genetics

If your kids are learning about genetics, you can do this edible double helix craft to show them how DNA is formed, what its different parts are, and what it looks like. The licorice will form the sides or backbone of the DNA and each color of marshmallow will represent one of the four chemical bases. Kids will be able to see that only certain chemical bases pair with each other.

• 2 pieces of licorice
• 12 toothpicks
• Small marshmallows in 4 colors (9 of each color)
• 5 paperclips

#19: Leak-Proof Bag

• Teaches Kids About: Molecules, plastics

This is an easy experiment that'll appeal to kids of a variety of ages. Just take a zip-lock bag, fill it about ⅔ of the way with water, and close the top. Next, poke a few sharp objects (like bamboo skewers or sharp pencils) through one end and out the other. At this point you may want to dangle the bag above your child's head, but no need to worry about spills because the bag won't leak? Why not? It's because the plastic used to make zip-lock bags is made of polymers, or long chains of molecules that'll quickly join back together when they're forced apart.

• Zip-lock bags
• Objects with sharp ends (pencils, bamboo skewers, etc.)

#20: How Do Leaves Breathe?

• Teaches Kids About: Plant science

It takes a few hours to see the results of this leaf experiment , but it couldn't be easier to set up, and kids will love to see a leaf actually "breathing." Just get a large-ish leaf, place it in a bowl (glass works best so you can see everything) filled with water, place a small rock on the leaf to weigh it down, and leave it somewhere sunny. Come back in a few hours and you'll see little bubbles in the water created when the leaf releases the oxygen it created during photosynthesis.

• Large bowl (preferably glass)
• Magnifying glass (optional)

#21: Popsicle Stick Catapults

Kids will love shooting pom poms out of these homemade popsicle stick catapults . After assembling the catapults out of popsicle sticks, rubber bands, and plastic spoons, they're ready to launch pom poms or other lightweight objects. To teach kids about simple machines, you can ask them about how they think the catapults work, what they should do to make the pom poms go a farther/shorter distance, and how the catapult could be made more powerful.

• Popsicle sticks
• Rubber bands
• Plastic spoons
• Paint (optional)

#22: Elephant Toothpaste

You won't want to do this experiment near anything that's difficult to clean (outside may be best), but kids will love seeing this " elephant toothpaste " crazily overflowing the bottle and oozing everywhere. Pour the hydrogen peroxide, food coloring, and dishwashing soap into the bottle, and in the cup mix the yeast packet with some warm water for about 30 seconds. Then, add the yeast mixture to the bottle, stand back, and watch the solution become a massive foamy mixture that pours out of the bottle! The "toothpaste" is formed when the yeast removed the oxygen bubbles from the hydrogen peroxide which created foam. This is an exothermic reaction, and it creates heat as well as foam (you can have kids notice that the bottle became warm as the reaction occurred).

• Clean 16-oz soda bottle
• 6% solution of hydrogen peroxide
• 1 packet of dry yeast
• Dishwashing soap

#23: How Do Penguins Stay Dry?

Penguins, and many other birds, have special oil-producing glands that coat their feathers with a protective layer that causes water to slide right off them, keeping them warm and dry. You can demonstrate this to kids with this penguin craft by having them color a picture of a penguin with crayons, then spraying the picture with water. The wax from the crayons will have created a protective layer like the oil actual birds coat themselves with, and the paper won't absorb the water.

• Penguin image (included in link)
• Spray bottle
• Blue food coloring (optional)

#24: Rock Weathering Experiment

• Teaches Kids About: Geology

This mechanical weathering experiment teaches kids why and how rocks break down or erode. Take two pieces of clay, form them into balls, and wrap them in plastic wrap. Then, leave one out while placing the other in the freezer overnight. The next day, unwrap and compare them. You can repeat freezing the one piece of clay every night for several days to see how much more cracked and weathered it gets than the piece of clay that wasn't frozen. It may even begin to crumble. This weathering also happens to rocks when they are subjected to extreme temperatures, and it's one of the causes of erosion.

• Plastic wrap

#25: Saltwater Density

• Teaches Kids About: Water density

For this saltwater density experiment , you'll fill four clear glasses with water, then add salt to one glass, sugar to one glass, and baking soda to one glass, leaving one glass with just water. Then, float small plastic pieces or grapes in each of the glasses and observe whether they float or not. Saltwater is denser than freshwater, which means some objects may float in saltwater that would sink in freshwater. You can use this experiment to teach kids about the ocean and other bodies of saltwater, such as the Dead Sea, which is so salty people can easily float on top of it.

• Four clear glasses
• Lightweight plastic objects or small grapes

#26: Starburst Rock Cycle

With just a package of Starbursts and a few other materials, you can create models of each of the three rock types: igneous, sedimentary, and metamorphic. Sedimentary "rocks" will be created by pressing thin layers of Starbursts together, metamorphic by heating and pressing Starbursts, and igneous by applying high levels of heat to the Starbursts. Kids will learn how different types of rocks are forms and how the three rock types look different from each other.

• Toaster oven

#27: Inertia Wagon Experiment

• Teaches Kids About: Inertia

This simple experiment teaches kids about inertia (as well as the importance of seatbelts!). Take a small wagon, fill it with a tall stack of books, then have one of your children pull it around then stop abruptly. They won't be able to suddenly stop the wagon without the stack of books falling. You can have the kids predict which direction they think the books will fall and explain that this happens because of inertia, or Newton's first law.

• Stack of books

#28: Dinosaur Tracks

• Teaches Kids About: Paleontology

How are some dinosaur tracks still visible millions of years later? By mixing together several ingredients, you'll get a claylike mixture you can press your hands/feet or dinosaur models into to make dinosaur track imprints . The mixture will harden and the imprints will remain, showing kids how dinosaur (and early human) tracks can stay in rock for such a long period of time.

• Used coffee grounds
• Wooden spoon
• Rolling pin

#29: Sidewalk Constellations

• Teaches Kids About: Astronomy

If you do this sidewalk constellation craft , you'll be able to see the Big Dipper and Orion's Belt in the daylight. On the sidewalk, have kids draw the lines of constellations (using constellation diagrams for guidance) and place stones where the stars are. You can then look at astronomy charts to see where the constellations they drew will be in the sky.

• Sidewalk chalk
• Small stones
• Diagrams of constellations

#30: Lung Model

By building a lung model , you can teach kids about respiration and how their lungs work. After cutting off the bottom of a plastic bottle, you'll stretch a balloon around the opened end and insert another balloon through the mouth of the bottle. You'll then push a straw through the neck of the bottle and secure it with a rubber band and play dough. By blowing into the straw, the balloons will inflate then deflate, similar to how our lungs work.

• Plastic bottle
• Rubber band

#31: Homemade Dinosaur Bones

By mixing just flour, salt, and water, you'll create a basic salt dough that'll harden when baked. You can use this dough to make homemade dinosaur bones and teach kids about paleontology. You can use books or diagrams to learn how different dinosaur bones were shaped, and you can even bury the bones in a sandpit or something similar and then excavate them the way real paleontologists do.

• Images of dinosaur bones

#32: Clay and Toothpick Molecules

There are many variations on homemade molecule science crafts . This one uses clay and toothpicks, although gumdrops or even small pieces of fruit like grapes can be used in place of clay. Roll the clay into balls and use molecule diagrams to attach the clay to toothpicks in the shape of the molecules. Kids can make numerous types of molecules and learn how atoms bond together to form molecules.

• Clay or gumdrops (in four colors)
• Diagrams of molecules

#33: Articulated Hand Model

By creating an articulated hand model , you can teach kids about bones, joints, and how our hands are able to move in many ways and accomplish so many different tasks. After creating a hand out of thin foam, kids will cut straws to represent the different bones in the hand and glue them to the fingers of the hand models. You'll then thread yarn (which represents tendons) through the straws, stabilize the model with a chopstick or other small stick, and end up with a hand model that moves and bends the way actual human hands do.

• Straws (paper work best)
• Twine or yarn

#34: Solar Energy Experiment

• Teaches Kids About: Solar energy, light rays

This solar energy science experiment will teach kids about solar energy and how different colors absorb different amounts of energy. In a sunny spot outside, place six colored pieces of paper next to each other, and place an ice cube in the middle of each paper. Then, observe how quickly each of the ice cubes melt. The ice cube on the black piece of paper will melt fastest since black absorbs the most light (all the light ray colors), while the ice cube on the white paper will melt slowest since white absorbs the least light (it instead reflects light). You can then explain why certain colors look the way they do. (Colors besides black and white absorb all light except for the one ray color they reflect; this is the color they appear to us.)

• 6 squares of differently colored paper/cardstock (must include black paper and white paper)

#35: How to Make Lightning

• Teaches Kids About: Electricity, weather

You don't need a storm to see lightning; you can actually create your own lightning at home . For younger kids this experiment requires adult help and supervision. You'll stick a thumbtack through the bottom of an aluminum tray, then stick the pencil eraser to the pushpin. You'll then rub the piece of wool over the aluminum tray, and then set the tray on the Styrofoam, where it'll create a small spark/tiny bolt of lightning!

• Pencil with eraser
• Aluminum tray or pie tin
• Styrofoam tray

#36: Tie-Dyed Milk

• Teaches Kids About: Surface tension

For this magic milk experiment , partly fill a shallow dish with milk, then add a one drop of each food coloring color to different parts of the milk. The food coloring will mostly stay where you placed it. Next, carefully add one drop of dish soap to the middle of the milk. It'll cause the food coloring to stream through the milk and away from the dish soap. This is because the dish soap breaks up the surface tension of the milk by dissolving the milk's fat molecules.

• Shallow dish
• Milk (high-fat works best)

#37: How Do Stalactites Form?

Have you ever gone into a cave and seen huge stalactites hanging from the top of the cave? Stalactites are formed by dripping water. The water is filled with particles which slowly accumulate and harden over the years, forming stalactites. You can recreate that process with this stalactite experiment . By mixing a baking soda solution, dipping a piece of wool yarn in the jar and running it to another jar, you'll be able to observe baking soda particles forming and hardening along the yarn, similar to how stalactites grow.

• Safety pins
• 2 glass jars

Summary: Cool Science Experiments for Kids

Any one of these simple science experiments for kids can get children learning and excited about science. You can choose a science experiment based on your child's specific interest or what they're currently learning about, or you can do an experiment on an entirely new topic to expand their learning and teach them about a new area of science. From easy science experiments for kids to the more challenging ones, these will all help kids have fun and learn more about science.

We can all agree that science is awesome. And you can bring that awesomeness into your very own home with these 20 safe DIY experiments you can do right now with ordinary household items.

1. Make Objects Seemingly Disappear Refraction is when light changes direction and speed as it passes from one object to another. Only visible objects reflect light. When two materials with similar reflective properties come into contact, light will pass through both materials at the same speed, rendering the other material invisible. Check out this video from BritLab  on how to turn glass invisible using vegetable oil and pyrex glass.

2. Freeze Water Instantly When purified water is cooled to just below freezing point, a quick nudge or an icecube placed in it is all it takes for the water to instantly freeze. You can finally have the power of Frozone from The Incredibles on a very small scale! Check out the video on this "cool" experiment. 

3. Create Oobleck And Make It Dance To The Music Named after a sticky substance in a children’s book by Dr Seuss , Oobleck is a non-Newtonian fluid, which means it can behave as both a solid and a liquid. And when placed on a sound source, the vibrations causes the mixture to gloopily dance. Check out these instructions from Housing A Forest  on how to make this groovy fluid funk out in every way.

4. Create Your Own Hybrid Rocket Engine With a combination of a solid fuel source and a liquid oxidizer, hybrid rocket engines can propel themselves. And on a small scale, you can create your own hybrid rocket engine, using pasta, mouthwash and yeast. Sadly, it won’t propel much, but who said rocket science ain’t easy? Check out this video from NightHawkInLight on how to make this mini engine.

5. Create "Magic Mud" Another non-Newtonian fluid here, this time from the humble potato. "Magic Mud" is actually starch found in potatoes. It’ll remain hard when handled but leave it alone and it turns into a liquid. Make your own “Magic Mud” with this video.

6. Command The Skies And Create A Cloud In A Bottle Not quite a storm in a teacup, but it is a cloud in a bottle. Clouds up in the sky are formed when water vapor cools and condenses into visible water droplets. Create your own cloud in a bottle using a few household items with these wikiHow instructions .

7. Create An Underwater Magical World First synthesized by Adolf van Baeyer in 1871, fluorescein is a non-toxic powder found in highlighter pens, and used by NASA to find shuttles that land in the sea. Create an underwater magical world with this video from NightHawkInLight .

9. Make Your Own Lava Lamp Inside a lava lamp are colored bubbles of wax suspended in a clear or colorless liquid, which changes density when warmed by a heating element at the base, allowing them to rise and fall hypnotically. Create your own lava lamp with these video instructions.

10. Create Magnetic Fluid A ferrofluid is a liquid that contains nanoscale particles of metal, which can become magnetized. And with oil, toner and a magnet , you can create your own ferrofluid and harness the power of magnetism! 

12. Make Waterproof Sand A hydrophobic substance is one that repels water. When sand is combined with a water-resistant chemical, it becomes hydrophobic. So when it comes into contact with water, the sand will remain dry and reusable. Make your own waterproof sand with this video .

13. Make Elephant's Toothpaste Elephant’s toothpaste is a steaming foamy substance created by the rapid decomposition of hydrogen peroxide, which sort of resembles giant-sized toothpaste. Make your own elephant’s toothpaste with these instructions.

14. Make Crystal Bubbles When the temperature falls below 0 o C (32 o F), it’s possible to freeze bubbles into crystals. No instructions needed here, just some bubble mix and chilly weather.

15. Make Moving Liquid Art Mixing dish soap and milk together causes the surface tension of the milk to break down. Throw in different food colorings and create this trippy chemical reaction.

16. Create Colourful Carnations Flowers absorb water through their stems, and if that water has food coloring in it, the flowers will also absorb that color. Create some wonderfully colored flowers with these wikiHow instructions .

17. "Magically" Turn Water Into Wine Turn water into wine with this  video  by experimenter Dave Hax . Because water has a higher density than wine, they can switch places. Amaze your friends with this fun science trick.

18. Release The Energy In Candy (Without Eating It) Dropping a gummy bear into a test tube with potassium chlorate releases the chemical energy inside in an intense chemical reaction. That’s exactly what's happening when you eat candy, kids.

19. Make Water "Mysteriously" Disappear Sodium polyacrylate is a super-absorbent polymer, capable of absorbing up to 300 times its own weight in water. Found in disposable diapers, you can make water disappear in seconds with this video .

20. Create A Rainbow In A Jar Different liquids have different masses and different densities. For example, oil is less dense than water and will float on top of its surface. By combining liquids of different densities and adding food coloring, you can make an entire rainbow in a jar with this video .

There you have it – 20 experiments for you to explore the incredible world of science!

Teaching Physics With a Real-World Context

Placed-based learning provides a way for high school students to directly engage with scientific phenomena in their daily lives.

British mathematician Roger Penrose said, “Sometimes it’s the detours which turn out to be fruitful ideas.” As a physics teacher, I’ve filmed or photographed a physics phenomenon, such as a rotating carousel or a rolling shopping cart, because I find it captivating and hope that my students will too. These detours have inspired fruitful learning experiences in my physics class. I can facilitate meaningful engagement by helping students connect what they learn in class with what they observe in the real world. 

I use place-based learning to engage students in their physical environment by encouraging them to ask physics-based questions about their surroundings. Using the walkSTEM philosophy developed by Dr. Koshi Dhingra, students can transform their questions into short, educational videos for the general public. This activity inspired my school to create walkSTEM @ Marymount four years ago.

The value of the current project, walkSTEM East Harlem, can be traced back to the need to cultivate a deeper interest in STEM among girls. A recent report by the Women’s Foundation of Boston suggests that one effective way to foster this interest is by introducing authentic, hands-on learning experiences that are relatable and community-based. 

Project Overview

I first introduced walkSTEM projects in my AP Physics class four years ago when we created a virtual walking tour of Central Park. My students regularly film real-world physics phenomena, and walkSTEM seemed like a natural extension of the work I had already been doing. 

This year, our Upper Campus relocated to East Harlem. This provided an opportunity for my students to learn about their new neighborhood and the hidden examples of physics in the school environs. As such, walkSTEM East Harlem, the final project for Honors Physics 2023–24, was born.

The project kicks off in January and concludes in early May. This timeline gives students multiple opportunities for feedback and revision. It is critical in that their work enters the public sphere; this needs to be their best work.

My students begin the project by observing examples of physics in our local neighborhood. For example, students might observe a hanging sign at a local business (translational and rotational equilibrium) or the door at Starbucks (Newton’s Second Law for Rotation). Students take photos at several locations with their mobile devices and then generate “observable questions” about the locations. Students complete their observations on their own, doing their observations on their way to or from school. This process takes approximately three weeks. Getting good photos of good physics with good questions is essential!

This is one point at which students tend to struggle—finding it hard to write questions that the general public may ask. For example, when thinking about a playground slide, “Why is the slide shiny?” is a better question than “How do you calculate the coefficient of kinetic friction of the slide?” At this point, students get feedback from me and from their peers and settle on one final location and question. 

Once their final location and question have been approved, students are required to produce a 90-second to two-minute video that highlights the location, states the place-based physics question, and provides a plain-language response to the question. This part of the process can present another challenge to students. As they write their scripts, I remind them that “shorter is better.” Here’s an example of an effective storyline arc:

Set the scene: “This is the Pacific Wheel on the Santa Monica Pier. The Santa Monica Pier is one of the most iconic locations in California and is also the western terminus of Route 66.”

Pose the question: “You will notice that the Pacific Wheel rotates at a constant angular velocity. Would the Pacific Wheel’s angular velocity change if there were more people on the Wheel—i.e., the Wheel’s mass was greater?”

Answer the question: “The Wheel is designed to rotate at a specific angular velocity based on a minimum number of people on the ride. Having every car filled will not slow the wheel down.”

Writing the script is often the most challenging part of the project. Students often try to use a combination of mathematics and physics equations to support their explanations. In order to translate complex physics concepts into plain-language explanations, students need a deep understanding of the physics associated with their location and question. While students receive feedback from me and from their peers, they’re also required to get feedback from a “general public audience”—their parents or guardians or a younger sibling. As Roman philosopher Seneca noted, “ Docendo discimus ,” or, “By teaching, we learn.”

Students then produce their videos using their preferred platform: Adobe Express, Keynote, or Canva. Here again, the narrative and storyline are important. Students are given the following visual presentation structure: 

• Physics connection
• Set the scene: Photo or video
• Set the scene: Location
• Pose the question: Annotate the photo or video
• Answer the question: Annotate the photo or video

Then once more to the feedback pool—draft videos are reviewed by their peers and me. This is when students can correct any errors before final publication.

Students then create a “virtual” tour on Google Earth. For each location, students create a placemark and embed the video into it.

You can access our walkSTEM East Harlem tour on Google Earth. 

Student Feedback on the PRoject

In order to produce an effective video, students have to demonstrate a deep understanding of their concept. They really have to know their stuff to explain it well! At the end of the project, students were asked to reflect on their learning experience and were given the following prompts:

1. Comment on how your final project represents your understanding of physics.

2. Comment on how your final project helped connect your understanding of physics to the real world. 

Their responses showed that they had a positive experience using this protocol:

“Our learning went outside the box, both figuratively and literally, and we were able to share the knowledge we gained in bite-sized videos with our community.” 

“I was able to choose my location and question to answer for this project; as a result, I became very interested in my topic—torque—and learned about its importance in the real world.” 

The takeaway: As a physics teacher, I want my students to ask questions about the physics and phenomena they observe in the real world. That’s why I love the walkSTEM protocol. All students have a framework by which they can answer their place-based questions with plain-language explanations for the general public.

Many people think science is difficult and needs special equipment, but that’s not true.

Science can be explored at home using everyday materials. Everyone, especially children, naturally ask questions about the world around them, and science offers a structured way to find answers.

Misconceptions about the difficulty of science often stem from a lack of exposure to its fun and engaging side. Science can be as simple as observing nature, mixing ingredients or exploring the properties of objects. It’s not just for experts in white coats, but for everyone.

Don’t take my word for it. Below are three experiments that can be done at home with children who are primary school age and older.

Extract DNA from bananas

DNA is all the genetic information inside cells. Every living thing has DNA, including bananas.

Did you know you can extract DNA from banana cells?

What you need: ¼ ripe banana, Ziploc bag, salt, water, washing-up liquid, rubbing alcohol (from a pharmacy), coffee filter paper, stirrer.

What you do:

Place a pinch of salt into about 20ml of water in a cup.

Add the salty water to the Ziploc bag with a quarter of a banana and mash the banana up with the salty water inside the bag, using your hands. Mashing the banana separates out the banana cells. The salty water helps clump the DNA together.

Once the banana is mashed up well, pour the banana and salty water into a coffee filter (you can lay the filter in the cup you used to make the salty water). Filtering removes the big clumps of banana cells.

Once a few ml have filtered out, add a drop of washing-up liquid and swirl gently. Washing-up liquid breaks down the fats in the cell membranes which makes the DNA separate from the other parts of the cell.

Slowly add some rubbing alcohol (about 10ml) to the filtered solution. DNA is insoluble in alcohol, therefore the DNA will clump together away from the alcohol and float, making it easy to see.

DNA will start to precipitate out looking slightly cloudy and stringy. What you’re seeing is thousands of DNA strands – the strands are too small to be seen even with a normal microscope. Scientists use powerful equipment to see individual strands.

Learn how plants ‘drink’ water

What you need: celery stalks (with their leaves), glass or clear cup, water, food dye, camera.

• Fill the glass ¾ full with water and add 10 drops of food dye.
• Place a celery stalk into the glass of coloured water. Take a photograph of the celery.
• For two to three days, photograph the celery at the same time every day. Make sure you take a photograph at the very start of the experiment.

What happens and why?

All plants, such as celery, have vertical tubes that act like a transport system. These narrow tubes draw up water using a phenomenon known as capillarity.

Imagine you have a thin straw and you dip it into a glass of water. Have you ever noticed how the water climbs up the straw a little bit, even though you didn’t suck on it? This is because of capillarity.

In plants, capillarity helps move water from the roots to the leaves. Plants have tiny tubes inside them, like thin straws, called capillaries. The water sticks to the sides of these tubes and climbs up. In your experiment, you will see the food dye in the water make its way to the leaves.

Build a balloon-powered racecar

What you need: tape, scissors, two skewers, cardboard, four bottle caps, one straw, one balloon.

• Cut the cardboard to about 10cm long and 5cm wide. This will form the base of your car.
• Make holes in the centre of four bottle caps. These are your wheels.
• To make the axles insert the wooden skewers through the holes in the cap. You will need to cut the skewers to fit the width of the cardboard base, but leave room for the wheels.
• Secure the wheels to the skewers with tape.
• Attach the axles to the underside of the car base with tape, ensuring the wheels can spin freely.
• Insert a straw into the opening of a balloon and secure it with tape, ensuring there are no air leaks.
• Attach the other end of the straw to the top of the car base, positioning it so the balloon can inflate and deflate towards the back of the car. Secure the straw with tape.
• Inflate the balloon through the straw, pinch the straw to hold the air, place the car on a flat surface, then release the straw.

The inflated balloon stores potential energy when blown up. When the air is released, Newton’s third law of motion kicks into gear: for every action, there is an equal and opposite reaction.

As the air rushes out of the balloon (action), it pushes the car in the opposite direction (reaction). The escaping air propels the car forward, making it move across the surface.

They’re also an excellent way to hone your electronics skills if you’re actively looking for jobs in IoT .

So, if you’re driven by a desire to innovate, have a passion for technology, or enjoy creating, let’s dive into some fun Arduino projects!

• What Is Arduino?

If you’re new to Arduino, you’re probably wondering, what exactly is Arduino?

Great question! Let me cover the basics before we dive into some easy Arduino projects!

Arduino is an open-source electronics platform consisting of easy-to-use hardware and software.

You'll often hear about Arduino and Raspberry Pi when it comes to microelectronics in 2024, but that's a discussion for another day.

An Arduino board is a programmable microcontroller that includes various inputs and outputs (I/O), like serial communication, digital inputs and outputs, and analog inputs.

This is very cool indeed and a far cry from the basic breadboards I used to learn about electronics during my undergraduate studies.

Arduino boards are typically used in a free and open-source development environment. Combining these allows you to write, upload, and execute code that controls your device, invention, or project.

One of the coolest ways to use Arduino is to get creative, whether you want to build a simple LED light device or are interested in IoT (Internet of Things) or robotics.

And if you’re just starting out, there’s a huge and active Arduino community that offers support, shares their own projects, and more. 

Of course, if you’re brand new to the world of Arduino and you’re not sure where to start, we’d definitely recommend complementing your projects with an Arduino course.

• What Skills Do You Need For Arduino Projects?

Let's set the record straight: you don’t need to be an expert to start working on Arduino projects! In fact, I genuinely think that Arduino projects can be great for all skill levels.

That said, you should probably have some basic skills before you get started, or at least be willing to learn them!

For example, Arduino projects usually involve C++ coding if you're building from scratch, so consider a C++ course if this sounds like fun, but you're not familiar with the language.

Let's take a look at the basics I think you should have to follow along with our Arduino projects:

• Basic programming knowledge: Even if you’re following along with someone else’s code, basic programming knowledge is useful for figuring out any issues that may come up.
• C or C++ skills: Arduino is based on C++, so it's really helpful to have C++ skills to create your own projects from scratch.
• Basic electronics knowledge: Arduino projects involve working with various electrical components, so it’s essential to understand the basics of current, voltage, and resistance.
• Ability to read schematics: Arduino projects often come with schematics that make them easy to replicate, so you’ll need to be able to read these to work with these kits or projects.

I should point out that it’s also really easy for complete beginners to pick up easy Arduino projects and learn these skills along the way.

But if you are feeling uncertain, I also think it helps to pick up an Arduino book for some extra help if you're brand new to the area.

I know from experience that it's always nice to have some reference materials on hand!

• Best Arduino Projects for Beginners in 2024

To get things started, I'll start with ten Arduino starter projects that are generally on the simpler side.

This means they require less time to put together, and they're also a great way to get a taste of what you can do with Arduino!

1. PC Info Panels

Download Source Code

Why We Chose This Project

First up on our list is one of the best beginner Arduino projects for newbies. I really like this as a gentle introduction, as you’ll use an Arduino Nano to interface between an LCD display and your computer’s USB port.

Once the electrical components are assembled, you can use open-source software called LCD Smartie to show different kinds of information on your LCD screen, including system stats like network utilization, CPU load, disk space, and more.

I also like that you can use your info panel to download RSS feeds or run other applications. Very cool!

2. Vintage Screensaver

This might be appealing to me because of the nostalgia, but if you're new to Arduino, simple projects like this vintage screensaver are a great way to start!

Inspired by 90s screensavers, you can get a healthy dose of 90s retro styling with the TVOUT and a Yourduino.

I also like that there are nine screensavers to choose from, making it a fun way to create an interesting decorative piece and even reuse an old CRT display.

Although you might need to dig around for a CRT display, as they're not very common anymore!

3. ArduSniffer

I really like this one, as it's a genuinely useful project! With the ArduSniffer, you can create a USB-powered gas detector with an LED display.

Sure, it does have more components than the first two projects on our list, but I want to gradually introduce you to more challenging projects as we work down the list.

That said, I think this is a great way to level up your skills. Plus, it's pretty affordable and offers detailed instructions.

4. Bluetooth Controlled RC Car

If you like remote-controlled cars (we’ve all had one at some point, right?!), you'll love this project, as it uses Bluetooth, an app on your phone, and an Arduino. 

I like that the instructions are pretty basic, as it makes it easy for you to put the car together and make it work.

But if you want to get creative, you can use a 3D printer (or printing service) to design a body for the car!

5. Stroboscope (Zoetrope)

A zoetrope , sometimes called a stroboscope, is a pre-film mechanical device that gives the illusion of animation or motion. I love this project, and it's great if you’re a cinema fan! 

To build this Arduino project, you can reuse a defunct Xbox 360 CD drive with a spindle motor to recreate this cool gadget.

You get all the instructions and source code you need in the instructable, making this a great way to create a short animation (or the illusion of one).

6. Portable Temp/Humidity Sensor with an LCD Display

I think this portable temperature and humidity sensor is a fun beginner Arduino project, as it's easy to understand really relatable.

This particular project uses an Arduino UNO R3, but you can use any 5V Arduino board you choose, and you can even purchase new parts or salvage some from your old projects.

The code, which was made using the Adafruit DHT library, is included in the instructions, and you can power your sensor using a power bank to display data in real time.

7. Simple Programmable Robotic Arm

Do you like robots? If the answer is yes, read on!

This is one of the best Arduino robot projects for beginners, as you'll create a simple and programmable servo arm using Arduino UNO and the Arduino IDE.

The robot arm itself uses buttons and potentiometers to record and play five programmed positions. 

I like that this can be powered by your computer’s USB port, but you can also use an external power supply if you ensure the servo can handle it.

It's easy to make the bot arm from readily available materials, and the code and circuit schematics are included.

8. Nano Piano

Do you fancy yourself as Beethoven or Bach? Just kidding, but if you like music, this is a cool Arduino project.

It is a beginner-friendly project with all the schematics and code you need to build a miniature piano with four keys using the Arduino Nano Every.

I also like that you can tailor the Nano Piano to your style by choosing your base (perf or protoboard) and deciding whether you want to create a housing with 3D printing!

9. Coin Sorter

Do you have pockets full of change you don't know what to do with? Maybe, maybe not! I mean, who uses real money anymore, right?!

That said, if you’ve ever wanted to sort your coins, this simple Arduino project might be one to try.

All you need is an Arduino UNO, a 16x2 display, and an infrared (IR) sensor to detect the differences between each coin, sending them through the appropriate hole.

I need to point out that it’s super important to follow the instructions as accurately as possible. This includes marking and cutting the sorting holes precisely and ensuring the slopes are appropriately angled.

You can even create a simple prototype from cardboard or 3D print a body for the sorter.

10. Blind Spot Monitoring System

Rounding out our list of projects for beginners, this is a really interesting Arduino project if you're intrigued by real-world microelectronics applications.

In fact, this project even takes its inspiration from the 2021 Mercedes Benz S-Class, which used ambient lighting to blink when a vehicle is detected in the blind spot. We've probably all seen these features in modern cars now, but it was revolutionary at the time.

In this case, we’ll be using an Arduino Uno and an RGB LED light strip to mimic the same thing. You can also set it to blink different colors depending on the position of the other vehicle relative to yours.

While there are many Arduino LED Projects to choose from, I really like this one as it's incredibly beginner-friendly and relatable.

• Cool Arduino Projects for Intermediate Users

Do you feel ready to take it to the next level? Let’s take a look at some intermediate-level projects!

11. Emotive Plant Pot

Ready for some more fun Arduino project ideas? Great, how do you feel about making an Emotive Plant Pot?

Now, let me take a second to say that this is not going to be Groot from Guardians of the Galaxy (I know!), but it's actually a 3D-printed plant pot with an LCD display that you can use to show cute faces.

You can even 3D print the components yourself with the included files. Just use the detailed instructions and schematics, and away you go!

12. Touch Interface Controlled Robotic Arm

We're back to robotics! If this is something you like, definitely check out this touch interface robotic arm.

All you need is an Arduino and any older Android phone to get started. I think this is also a cool way to get more mileage from older tech! 

Now, as you'd expect, this project is a little more complex, but the schematics and code are provided, and there’s even an assembly guide with a clear video to demonstrate the steps.

You can also 3D print the components yourself or use a 3D printing service with the provided files.

Note that creator Maurizio Miscio states you can contact him for the graphical interface app’s code.

13. Hidden Smart Bookshelf

This one just sounds cool, so I had to include it! The idea here is to create a Hidden Smart Home Bookshelf that you can use to conceal items within a cabinet or shelf that’s meant to look like a full bookshelf.

The creator has even included a very detailed video to cover the building and assembly process.

If you want to access the Arduino source code, head over to the creator’s GitHub , and you can either follow along exactly or make your own improvements.

I also think that if you have extra space, you could scale this up into a concealed closet or door!

14. Neopixel Cake

I think this is one of those super cool Arduino project ideas that you can use to make a splash at a party or special event.

Yep, you can make a uniquely memorable cake that uses flexible LED matrices and an Arduino.

The matrices themselves are embedded into the cake, then covered with fondant icing to allow light diffusion and a much better effect. Watch out Cake Boss!

I also found that you can even program cool light effects or text into the LED matrix so it can display whatever you want.

Just follow the detailed video demo and make sure you have a cake ready!

15. Automatic Humidifier

If you live somewhere hot and dry, you probably know all too well how important it is to have a humidifier.

Well, you can build your own now! I love this project to create an automatic humidifier, and it's straight from the Arduino Project Hub.

This project revolves around using a DHT11 temperature and humidity sensor to detect environmental humidity, and this can trigger the humidifier whenever the detected humidity is below a set level.

16. CNC Drawing Machine

This is another flashback for me to my undergraduate studies and the class I took in electronics and manufacturing.

The idea here with this Arduino project is to create a CNC (Computer Numerical Control) plotter out of an Arduino Nano board and two old DVD writers.

This is definitely another slightly old-school project, but I love the way it can be used to create 2D or 3D images on plain or smooth surfaces with an Arduino and a printing mechanism. 

17. 32-Band Audio Spectrum Visualizer Analyzer

This is another project for music lovers, as it's a cool Arduino project to create a 32-band audio or music frequency visualizer (also called an analyzer).

I found that this audio visualizer mixes signals from the left and right channels to ensure no beats are missed, and it also has five display modes that you can switch with the push of a button.

It's also cool that the audio feed can be taken from a line out or the headphone port of an amplifier or sound system!

18. Mind Control Drone

Now we’re not promising that this project will make you into the next Charles Xavier, but with a Mindwave Neurosky sensor and an Arduino, you can have a slice of this futuristic idea by building a mind control drone.

Let me make it super clear! This project doesn’t allow you to fly a drone with your mind, per se.

But you can control the drone’s liftoff and landing with your mind, which is pretty cool!

I think this is an awesome project for learning how to hack a PCB and control it digitally.

It’s also worth mentioning that the creator warns that you may mess up your drone and its controller when building this project, so be careful !

19. IoT Pet Feeder

If you’re looking for Arduino IoT Projects, this is a great choice, as you can build a smart food dispenser that can be controlled from your phone. 

I like these kinds of projects, as they're practical and great for enthusiasts who also want to pursue a career in electronics.

All you'll need to create it is an Arduino UNO, a servo, a PIR motion sensor, and a small speaker.

You can even adapt this project and turn it into an automatic bird or squirrel feeder for your backyard!

Feel free to set your smart pet feeder up any way you’d like, but the default instructions are designed to set the feeder to beep at a set interval. Then, when your pet investigates the sound, a PIR motion sensor triggers the servo to dispense food. 

If you’re a fan of Back to the Future, think of this as your own way to feed your very own Einstein!

20. Smart Dustbin

Rounding out our intermediate project list, this is a full project kit that you can use to create a hands-free, self-operating dustbin that's controlled with claps or foot taps. 

This is pretty cool and a great way to add some electronic magic to your ordinary household items. You’ll just need an audio sensor to detect your claps or taps.

The dustbin can also send IoT notifications to let users know when the bin is full, thanks to an ultrasonic sensor that detects garbage levels. 

• The Best Arduino Projects for Advanced Users

If you feel like your Arduino skills are at the expert level, or if you’re feeling adventurous, these advanced projects might be the right ones for you. Let’s take a look!

21. Star Tracker (Low Cost)

If you like looking into space, this is a great Arduino project, as it uses an equatorial mount to take pictures of the sky at night.

If you’re not 100% sure what that means, no problem!

An equatorial mount is a telescope mount that allows telescopes or cameras to follow the earth’s rotation, ensuring any long exposures come out clearly. 

I also found that this project creator claimed the Star Tracker is easier than putting together Ikea furniture and just about as affordable. What an endorsement!

Despite being an advanced project, the Star Tracker is relatively user-friendly, with all the requirements listed in the GitHub repo.

Be sure to share your photos with us after you build this project!

22. The Gaggiuino Coffee Machine

Do you like coffee? I have a strong suspicion that the answer is yes!

In that case, this is one of the best Arduino projects for you! But you don’t need to be an engineering student to give it an espresso shot (get it?). 

This project uses an Arduino or an STM32 Blackpill to create a “smart coffee” experience, where the end product is an aftermarket mod of many coffeemakers.

There’s even an active community around this mod, which you can find on their Discord server , along with videos from project users.

23. Automated Bean Sprouter

If you like the idea of self-sustainability and growing your own foods, you might be intrigued by this project! What's more, if you love bean sprouts, you have to try it!

The idea here is to build your own automated bean sprouter by using stacked trays, a rotating motor, and a watering system to keep your sprouts hydrated while helping air circulate and keep mold growth at bay. 

This is another super practical project that you can actually use in your daily life, which I really like.

The project page includes all the necessary information, including the component list, schematics, and code.

As an advanced project, it’s not the easiest, but you’ll never need to buy sprouts again!

24. UV Meter and Breathalyzer Keychain

This is a really interesting Arduino project that uses a UV sensor to create your own alcohol breathalyzer in the form of a keychain.

All you need to create this handy keychain is an Arduino Pro Mini 328 and an Arduino UNO (or FTDI). The keychain itself is powered by three 200mAh Li-ion batteries that you can recharge via the USB charging port.

To finish things off, you will use an OLED screen to display everything you need.

Detailed instructions are provided with this project, including 3D files so you can print the spherical casing yourself (or get it printed by a 3D printing service). 

25. Path Memorizing Robot

I like this project, as it's a classic for electronics students and anyone interested in self-driving cars.

You'll just need to use an Arduino Uno to control a little robotic car designed to navigate through a predefined path before returning to its starting point.

Before you create this path-memorizing robot, you’ll need to build a regular remote-controlled car using an IR receiver and remote.

But this is super easy if you follow the instructions and use all the provided code and schematics.

26. Arduino 3D Wire Bending Machine

I think this is a cool project if you like to be creative with industrial materials.

The idea here is to create an Arduino-based wire-bending machine that you can use to bend wires into all sorts of 3D designs.

You'll use an Arduino to control the motor and wire feeder movements, while a 3D-printed jig allows the machine to bend the wire into your desired shapes.

I also like that you can bend wire of varying shapes and diameters and adjust the radius and bending angle. 

This project itself involves mechanical, electrical, and computer engineering all in one, making it a fantastic choice for engineering students or professionals.

27. Camera Slider

Here, we have another cool Arduino project for photography enthusiasts.

In fact, if you've ever wanted to create cinematic shots with your camera, you might have considered a camera slider. Well, this is the project for you!

The plan here is to create a motorized slider for your camera that will allow you to achieve smooth movements and get cinematic shots.

You’ll need aluminum, a timing belt, and stepper motors, along with an Arduino to move the camera. You also need a rotary encoder that allows you to move the slider back and forth.

You can use practically any camera you want in this rig, as long as it can attach to the DSLR mount!

28. Self-Parking Car with Ultrasonic Sensor

Maybe you fancy yourself as the next competitor to Elon Musk’s Tesla?

Or maybe you just think self-parking cars sound cool?

Either way, I think this is a really fun build that allows you to create an advanced self-parking car via path-finding algorithms.

All you need to dois order the full kit, and you’ll be ready to get building!

29. LED Cube

We're getting close to the end of our list, and I thought it would be fun to include something cool to look at!

With this LED Cube project, you can build a complex LED cube with 512 LED lights, and this can be programmed to show cool lighting patterns and all sorts of effects.

I also really appreciate that the creator documents the building process in a YouTube video, making it easy for you to follow along. 

Schematics and code are all provided, so all you need to do is gather the components, and you’re ready to build!

30. Magnet Plant Levitation System

Here we are, the final Arduino project on my list!

And what a way to wrap things up, but with a super cool Arduino project that suspends a plant in mid-air by using the power of electromagnetic fields.

It honestly feels like science fiction, but nope, this really works! Just follow the tutorial, as it offers a detailed guide, including the STL files for the 3D-printed components.

I know the list of components required for this project is long, but I really think the end result is totally worth it to build a plant levitator!
