12 Award Winning Science Projects for 10th Graders

Published on march 8, 2018 at 7:58 am by sieni kimalainen in lists.

Here we are to find out which some award winning science projects for 10th graders are. If you’re out of ideas, we hope that you’ll pick something of the interest for you from the list.

So, you are a fresh high-schooler with huge ambitions, and science is the field you want to try yourself out. That’s great. But before considering award winning science fair projects for high school, you should first get some guidelines for conducting your project.

But if you already have experience from before, with award winning science fair projects for 9 th grade, then you can skip this introduction, because you are probably familiar with the topic. But, nevertheless, as the ancient Romans used to say – repetitio est mater studiorum (repetition is the mother of learning) it is not bad idea to go through it once more.

Award Winning Science Projects for 10th Graders

Anyway, starting any science fair projects means thinking about it in general, and the first thing is, of course, choosing your field of interest, whether it is any particular field of biology, physics, earth sciences or whatever else. For a winning science project, you should also pay attention to current hot topics in science (if, you are not a genius which can think of something revolutionary, which is not impossible either). Such topics include environmental issues, health issues, resolving problems of pollution, food, but also some things that would make everyday life easier. Now when you have gotten your topic the first thing you should think about is making of a hypothesis: why you are doing this particular thing, why is it important, in which way does it help the science? A good and cogent hypothesis actually helps a lot; both with making your task clear to yourself and making it interesting and clear to the audience.

Next steps include (depending on the topic of course) preparing and making the experiment and/or gathering the data, analysis, and a conclusion or a resulting product in the end. Sounds easy, but it does not necessarily need to be (once again depending on the subject you have chosen). But, no need to worry, that’s why you have here examples of the award winning science projects for 10 th graders that will be your guide for a good experimentation procedure and other steps of your project.

Anyway, from this very short introduction on the basics of scientific research, we go closer to our list. There were plenty of places where we got really interesting ideas on science projects, and the info on which the award winning science fair projects for 10 th graders are. These were, among others, Education , Science Project Resources , Julian’s Science Fair , All Science Projects , and Home Science Tools (psst, if you are too lazy there are some last-minute fair project ideas you can check out on this website). It was a hard choice, in the end, making a proper list for the award winning science projects for 10 th graders, but from all the suggestions we have tried to pick the best ones and cover as much scientific fields as possible. But in the end, if you are going to win an award with your project or not, depends mostly on your effort. You can also check 10 Winning Science Fair Projects for High School for high school in general, not only for 10 th graders, including 11th grade science fair projects or science fair projects grade 12 for example.

And in the end just one more thing. These 10th grade science fair projects are project examples of already existing ones. Instead of copying them, you should rather use them as guidelines and ideas for something of your own and original. Think about them as an inspiration, and let’s see which those award winning science projects for 10 th graders are:

12. What is the better method of learning: reading or listening?

Field: psychology

This is an interesting topic that people often are puzzled about. And in the end, there are opinions that some people are just better at reading and observing while others are better learners by listening. Well, in this project you are going to debunk some myths.

30+ Science Fair Projects That Will Wow The Crowd

February 20, 2022 by Ana Dziengel Leave a Comment

Are your children signing up for the science fair this year? Have you begun the arduous task of looking for science fair projects that might pique your child’s interest? Or do you have a child who already has ten ideas they have been dying to try?

The science fair is a great school tradition and a memorable experience for many children (I still remember the life size plaster penguin I made in 5th grade), and if your school doesn’t conduct one, consider starting it!

This year if you are on the lookout for science fair projects I challenge you to think beyond the vinegar volcano (we have “Volcano Alley” at our school because there are so many volcano projects every year). I know, vinegar volcanoes are like a rite of childhood passage, but there are so many other amazing science ideas out there! I have compiled a list of 30+ science fair projects for kids based on their grade level below. Before we get started I wanted to share some tips for getting the most out of the science fair.

This post contains affiliate links.

Science Fair Tips

Don’t do the project for your child! This is my number one tip. Many parents have a tendency to jump in and make children’s work “more presentable” or to assist their child so much in the project that it’s hard to know who actually did it. Listen I get it, science is fun and you want your child to have a wonderful presentation…but that’s not really what the science fair is about. It’s about your child learning how to do scientific research and present their findings in their own way. Think of yourself as a helpful guide NOT an assistant, and definitely not the boss.
Choose something age appropriate When your child is choosing the science fair idea they want to try, make sure it’s age appropriate. Sure we’d all love to make a working robot but there’s nothing more frustrating than trying a project that may be too advanced for the skills of your child. And that’s when a lot of parents resort to doing the project instead. Not a good solution. So make sure your child is capable of completing the steps them self.
Make a list of three ideas Have your child select three science fair project ideas and then go over the choices with them. Make sure they understand the steps involved in each project and wether or not they feel comfortable in executing those steps on their own with your guidance.
Follow your child’s interests Encourage your children to explore some ideas based on interests they already have. Here’s a list of science books with projects based on things your child already loves!
STEAM it up! STEAM projects rock the science fair!!! A great way to get kids to become more familiar with STEAM concepts it to pick science projects that crossover into art, math, engineering and more! Two STEAM books to consider are STEAM Kids Play and Learn (my book!) and STEAM Kids ebook. Both books will get you started with some great ideas!
Read our Science Fair Mini Guide I created this mini guide to walk kids through all the steps for completing their science fair project. You can check out the full guide here:

Speak like a scientist! Science Vocabulary to use in your presentation

We’re almost ready to get to the projects! Before we begin, let’s review some science terms. In fact, using these terms in your science fair presentation will be sure to impress your friends and adults!

When you watch, see, or notice something you are making an observation
When you ask who, what, when, where, why, or how, you are forming a question
When you read a book or an article about your observation, you are doing research
When you make a guess based on your observation, question, and research, you are forming a hypothesis
When you test your hypothesis, you are conducting an experiment
When you change one factor in your experiment at a time while keeping everything else the same, you are changing a variable
When you take notes in your journal and write down what you see happening in your experiment, you are logging data
When you examine, or look at, your data, you are analyzing it
When you are able answer your question, you are coming to a conclusion

30+ Science Fair Projects for Kids

Now let’s get on with the science fair projects! I have organized the projects by age/grade level. Click the titles to be taken to the project instructions, unless the instructions follow below.

If you’d rather have the science fair projects list organized by subject you can download our hyperlinked PDF by subscribing to our email list here .

Kindergarten-1st Grade Science Fair Projects

3. Shiny Pennies

A classic experiment that kids love is Shiny Pennies . Collect dirty tarnished pennies and have kids soak them for a minimum of 5 minutes in different acidic liquids. We used vinegar, salsa, lime juice, and lemon juice. After soaking, remove them from the solution and rinse in soapy water then compare which ones are shiniest. Take notes on which acid worked best to shine the pennies. Variation: Don’t rinse all the pennies after removing them from the different liquids. Can you see a difference in the rinsed vs. non-rinsed pennies? Leave them overnight and see if any of the copper oxidizes (turns green) on the non-rinsed pennies.

Science Projects for Class 10: Physics

You can learn all concepts of the Physics Class 10 syllabus through experiments, projects, and models as these give you a practical understanding of theoretical concepts. To help you in this endeavour, we have enlisted some ideas for Science projects for Class 10 here. Experiment and explore!!

1. Simple Pendulum Project

To conduct a simple pendulum experiment, suspend a mass from a rigid support, measure the length, and determine the displacement angle. Thereafter, record the time it takes for one complete oscillation as the period. You have to repeat the experiment at different heights. Now, analyse the data to explore the relationship between pendulum length and period. You need to ensure safety measures and keep swings small for accurate results.

This classic physics experiment helps us understand periodic motion. Also, it helps us learn about the factors that affect periodic motion.

2. Ohm’s Law Verification Project

To verify Ohm’s Law, you need to set up a simple circuit with a power source, an ammeter, a voltmeter, and resistors of varying values. In the circuit, connect the components in series. After that, record current and voltage readings at different resistor values. According to Ohm’s Law (V=IR), the voltage (V) should be directly proportional to the current (I) across the resistor, validating its linear relationship. Therefore, you have to use a range of resistances to observe consistent results to verify the law.

Therefore, this experiment will help you understand and apply the fundamental relationship between voltage, current, and resistance in electrical circuits.

3. Sound Waves and Frequency Relationship Investigation

To identify the relationship between sound wave frequency and pitch, you can use tuning forks and a frequency counter. Start by striking the tuning fork. Now, place the tuning fork near the frequency counter’s microphone. Thereafter, record the frequency displayed on the counter. You must repeat the process with tuning forks of varying sizes. Higher frequencies correspond to higher pitch.

This experiment demonstrates the direct connection between sound wave frequency and perceived pitch. This connection explains the principle that higher frequencies result in higher-pitched sounds. Therefore, the project provides a hands-on experience for you to understand the concept of how frequency influences the auditory perception of pitch.

Science Projects for Class 10: Chemistry

In this section, we have some common topics for Science Projects for Class 10 to enable you to understand Chemistry better. Create and conquer!!

1. pH Levels in Household Products Calculation

To test pH levels in household items at school, you need to gather samples of cleaning products, beverages, and fruits. Use pH strips or a pH meter, available in science supply stores. Now, dip the strips into the liquid samples or immerse the pH meter probe, then compare the colour change on the strips or the numerical reading on the meter with a pH scale.

This simple experiment will help you understand acidity and alkalinity, which is an essential topic of Class 10 Chemistry.

2. Rust Formation and Prevention Experiment

For this Chemistry project, start by exposing metal samples to different conditions, such as moisture, salt, and air. For a successful experiment, you need to observe and document rust development over time. Whereas, for rust prevention apply various protective coatings like paint, oil, or corrosion-resistant substances. Now, compare the effectiveness of each method by measuring rust accumulation.

This Science project will help you learn about the impact of environmental factors on metal corrosion and explore practical methods for rust prevention. This will, in turn, help you equip yourself with an expanded knowledge of material science.

3. Chemical Reactions in Cooking

You can create a science project on chemical reactions in cooking by selecting recipes with noticeable reactions, like baking a cake or making bread. Thereafter, identify key ingredients transforming, such as leavening agents, acids, or yeast. As you witness the changes, document the alterations in texture, colour, and taste as indicators of chemical reactions. For this, you need to use scientific methods to measure variables and explain the science behind culinary transformations.

Now, showcase your project with visuals, data analysis, and explanations to highlight the correlation between chemical reactions.

To explore microorganisms in food spoilage, collect various perishable items and expose them to different environmental conditions. Now, monitor changes in smell, texture, and appearance over time. Further, you can use sterile swabs to take samples and cultivate microorganisms on agar plates. Identify and analyze the types of bacteria, moulds, and yeast present. Thereafter, introduce factors like temperature, moisture, and preservatives to observe their impact on microbial growth.

Through this experiment, you will explore how external factors influence the penetration of microorganisms.

2. Photosynthesis and Light Intensity Project

For this Science project, you need to set up a controlled experiment with potted plants. You must place them at varying distances from a light source to ensure that temperature and water availability remain constant. Now, measure oxygen production or carbon dioxide absorption to affirm the photosynthesis process. You should record data over time to create a graph depicting the relationship between light intensity and photosynthesis.

With this experiment, you will discover how light influences the rate of photosynthesis. By gaining practical knowledge of photosynthesis, you will be able to have a better understanding of plant biology and environmental factors.

3. Genetic Variation in Plants Project

Start by collecting seeds or plant cuttings from different sources. Thereafter, plant and cultivate these plants under identical conditions to eliminate external factors. Now, you have to observe variations in traits such as height, leaf shape, or flower color. Also, analyze the genetic basis using techniques like genetic markers. These findings will help you to highlight the impact of genetics on plant variation.

Thus, the project offers an opportunity to understand and embrace the biodiversity around us. It will also enable you to learn about the fundamentals of genetic principles.

How the Drive to Be Socially Connected Can Lead to School Improvement

The science of networking can help schools achieve meaningful and enduring change.

Illustration of a boat full of people parting a large wave

We often think of a school improvement initiative as occurring in uniform stages toward some predetermined end goal in a strategic plan. Everyone moves together on the same path toward the same destination.

This is a transactional view of change that doesn’t consider the complexity of humans and the challenge of scaling sustainable and meaningful change. We hold different beliefs about what matters in education, have complex identities both inside and outside of our schools, and are highly influenced by our social context.

As the research below shows, complex change—that which leads to lasting behavioral change—is both social and nonlinear. Using the science of networks can enable school leaders to design and implement more humane and enduring school improvement initiatives that build on our desire to be socially connected.

Individual Learning depends on Social Learning

Recent books such as Alex Pentland’s Social Physics: How Social Networks Can Make Us Smarter and Damon Centola’s Change: How to Make Big Things Happen reiterate the power of social networks in enabling change. For instance, in a variety of studies using big data, Pentland concluded that synchronizing break times in the workplace leads to increased productivity and that peer rewards (where individuals were paired and asked to work toward the same goal for a reward) drastically increased goal completion.

The big idea of their research into social change is that individual learning depends on group learning. Because school improvement initiatives are often about changing established beliefs and social norms related to teaching and learning, there will inevitably be individual resistance. Yet our ability to see others engaging in these behaviors can establish the social proof necessary to view the change as legitimate and worthy. The flow of ideas within our social networks can shape our individual behaviors. So what does this mean for the design of school improvement initiatives?

Designing Complex Contagions

Successful school improvement initiatives require complex contagions. Simple contagions, where information travels fast across a social network (think funny video or meme), spread easily but don’t lead to behavioral change. Simple contagions can spread in a network of weak ties passed on by acquaintances or strangers. Centola uses the idea of fireworks to describe these kinds of contagions; one connection can directly spread information to many. The information spreads fast and far, but only superficially.

On the other hand, complex contagions—those that lead to behavioral change—require strong ties to people we trust, respect, and admire (think changes such as embracing culturally responsive pedagogy or adopting authentic assessments). This is because of the perceived risk of change, in particular if it means our standing or reputation might be perceived differently by our social networks.

Centola describes these networks as fishing nets . The spread of ideas is slower, traveling from neighbor to neighbor. That said, the interconnectedness of the network means that people see change occurring across multiple strong ties at the same time, influencing them to adopt.

One way to produce complex contagions within our schools is to take a staged approach to improvement initiatives. Instead of asking all teachers to take part from the beginning, some early adopter groups can trial, model, and share about the change before it is more widely implemented. For example, specific departments or grade levels within a school can opt in to be part of the first cohort of teachers who will engage in a proposed change.

These individuals, excited and motivated by the change, can develop authentic stories about how the initiative supports students in the classroom. They will share stories formally and informally with colleagues to generate inspiration and reiterate the importance of the change. Inviting colleagues to take part who are connected and/or geographically close to each other can build the tipping point that is required for wide-scale adoption.

It’s important to note that the most connected and influential teachers are not necessarily the best people to include at the beginning of a change initiative; their social networks may dissuade them from taking risks that compromise their standing. Teachers on the periphery of the network may be more likely to be pioneers.

Knowing What’s Relevant to People Matters

Viewing a change as relevant is also key to the adoption of new behaviors in school. Yet what’s viewed as relevant is also subjective: Sometimes we want to see people like us adopting the change, and sometimes we want to see people different from us adopting the change. Centola shares three relevance principles.

If we need to view a change as useful to us, we benefit from seeing people similar to us adopting it.
If we need to create emotional excitement or loyalty, the same is true (benefit from similarity ).
However, if we need to believe that a change is widely accepted, we benefit from seeing a diverse set of people adopting it.

School leaders can use these three relevance principles to design improvement initiatives that speak to the needs of their teachers. Likewise we may strategically mix and match examples, starting with an initial presentation to show the wide-scale adoption of proposed change, followed by a session with teachers within the school sharing how they have implemented the change in their classrooms.

Tipping Points are Real

The idea of tipping points, moments of critical mass, may make us think of Derek Sivers’s TED Talk “How to Start a Movement .” In the video, we witness a sole individual dancing on a hill. Through the inclusion of some brave followers, eventually the dancing few turn into a movement of hundreds of people. The video provides an excellent visual metaphor of how tipping points function: Once the number of advocates of a change grows, the risk of adoption goes down. It becomes “safer” to embrace a change when it is broadly supported.

What’s interesting is that studies have now quantified the idea of a tipping point. If we want sustainable and lasting change, schools require at least 25 percent of teachers to advocate for those behaviors. The magic number is 25 percent. In school improvement initiatives, leaders can responsively plan by assessing the number of advocates.

If the number of adoptees is still less than 25 percent, leaders may opt to continue with an initiative in a staged manner to create a broader base for change. Then, once it’s clear that the 25 percent threshold has been reached, the change may be extended to the rest of the teaching staff. In this way, we can shape social networks that are more receptive and responsive to a proposed change.
