Seed Germination Experiment

Watching seeds grow is an amazing science project for kids! Our  seed germination experiment allows kids to see up close to how a seed grows! Learn about the steps of seed germination, and investigate what conditions a seed needs to germinate. Easy science experiments are great for kids of all ages!

Seed Germination In A Jar

Also check out our list of other fun science experiments you can in do a jar! >>> Science in a Jar

• Paper Towels or cotton wool
• Seeds (see our suggestions above)

H ow To Set Up Your Seed Experiment

STEP 1:  Fill the jar with paper towels. Kids can fold them and push them down into the jar. This is also great work for little hands.

STEP 2:  Gently water your seed jar to wet the paper towels. DO NOT FLOOD IT!

STEP 3:  Carefully push seeds down into the paper towels around the edge of the jar so they can still be seen. Make sure they are firmly held in place.

TIP: One easy way to get your seeds to germinate faster is to presoak them in a shallow container of warm water for up to 24 hours. That will soften the hard outer shell of the seed. Don’t soak for longer as they may go moldy!

Our mason jar below includes sunflower, pea, and green bean seeds!

STEP 4: Put your jar in a safe place, and check in regularly to observe any changes.

It all starts with a single seed!

Watching how a seed grows and using a mason jar gives you a front-row seat for observing it all! Sprouting seeds is perfect for a spring STEM activity !

Another fun way to sprout seeds, especially at the end of winter, is with a mini greenhouse made from plastic bottles.

What Is Seed Germination?

First, let’s learn a bit more about germination. Seeds grow into a new plant through a process called germination. Germination is the sprouting of the seed or the very beginning of plant growth.

Availability of water, cold temperatures or warm temperatures, oxygen, and light exposure may all be a factor in starting germination or keeping the seed dormant. What conditions are needed for germination will vary between plants, as each has adapted to the biome in which they live.

Stages of Seed Germination

First, the seed absorbs water. This causes the seed to swell and the outer coating to break. Then the seed starts to break down some of the food that is stored in it. Most seeds will need oxygen in the air in the soil for this to happen.

Eventually, when the seed has grown leaves it can make its own oxygen and absorb carbon dioxide through photosynthesis .

Once the seed coat breaks open, the first root grows, called the radicle. In almost all plants, the root comes before the shoot.

Once the root starts to grow, it can now absorb water and nutrients from the soil, instead of getting it from the seed coat.

After the root, the plant’s stem starts to grow. When it reaches above the ground, the leaves begin to grow. This is when the plant no longer has to rely on the stored starch (cotyledon) that comes from the seed.

Turn It Into A Science Project

This simple seed experiment is a great introduction for preschoolers to growing plants , and a fun plant experiment for older kids to investigate what conditions seeds need to germinate.

Older kids can use a science experiment worksheet to write down their observations about how the seeds are growing. While young kids can draw or observe the changes!

There are so many fun questions you can ask…

• Do seeds need light to germinate?
• Does the amount of water affect seed germination?
• Do different types of seeds germinate under the same conditions?
• Does salt water affect seed germination?

Explore how fast different seeds germinate by comparing different kinds of seeds under the same conditions. We tried sunflower seeds, peas, and beans in our seed jar.

Or keep the type of seed the same and set up two mason jars to explore whether seeds need light to germinate. Place one jar where it will get natural light and one in a dark cupboard.

Another idea is to investigate whether seeds need water to germinate and how much. Set up three jars, and measure out how much water goes into each so that one is fully wet, half wet and one has no water.

How To Observe Seed Growth

Get your magnifying glass out and check out all the angles of the seeds. Can you find the different stages of seed germination described earlier?

What do you see in your seed jar?

• You are looking for a root to pop out of the side.
• Next, you are looking for a root to push down into the soil.
• Then, you are looking for root hairs.
• Next, look for the seed to push up while the root hairs push down.
• Lastly, you are looking for the shoots to come up!

The mason jar gives a stunning view of this seed experiment! My son loved being able to see the changes so easily.

This is what we should have done – instead we tried plastic bags to grow the seeds in, and they got foggy with condensation so it was hard to see the root! Aw, well. Lesson learned. Next time – grow them in a jar! lol!

We just started our beans in a jar last week. Looking forward to seeing what happens this week.

We’ve just done the same 🙂 Put the beans in the jar instead plastic bags 🙂 Mr Frog is so excited observing the bean growing!

Wonderful learning activity! Thanks for linking up at the Thoughtful Spot Weekly Blog Hop!

My girlie is very curious about planting and asks tons of questions about the seeds and what happens with them in the soil. This is a great way to show her clearly enough the whole process of the seed’s growing. Thank you for this idea!

What kind of pea seeds did you use?

Good question. I don’t remember the band or name but it was a common package from the store.

This looks like so much fun! Can’t wait to try with my 4 and 2 year old son and daughter. We’re always looking for affordable, educational and fun activities. This is perfect. Happy to have stumbled onto this site!

Do you cover the jar? Do they need to be near a sunny window? Are you supposed to water them? Thanks!

Wonderful! Thank you!

Hi! I did not cover the jar. They were on a table in front of window that did get sunlight at some point during the day. We did not water daily. I added a tiny bit here and there but not much at all. We actually went away for a week and came back to them being so tall which you can see in the picture above. Thats a week with no water what so ever!

What kind of beans did you use? Pinto? I’m wanting to start this activity here soon with my little in-home daycare. 🙂

We used green beans, sunflowers, and green peas!

Just double checking no soil, just paper towels. This is our spring break project. I can’t wait.

Right no soil!

hello! I’m going to try this with my kindergarten class. Did you use dried green beans infrom a bag (like at the supermarket)? Or fresh ones?

Where did you get your seeds? Did you buy them fresh and pick the seed out off the pods or take it out of the shell? I’m interested in doing this but I don’t want to buy the wrong ones.

Simple seed packets from the grocery store!

that was so cool

What a great learning activity. I am featuring this with a link on my blog.

We are getting ready to start this project today with our preschool class. One thing i have not been able to find is, how much water/how wet do the paper towels need to be?’

super cool!!!

I cant wait to try this out with the 4 year old children at the our Early Learning Centres I am grateful to have found this page. Thank you so much.

At any point do you add soil to the jar or transfer the plant out so it can grow bigger? If transferring, what’s the best way to move them out of the jar and into a pot? What stage of growth should they be at before doing so? Does this method work for any type of seeds? This is perfect for the plant project I want to start with my in-home daycare but I wanted to use seeds from foods they eat and can replant as a way of incorporating recycling into the other lessons learned but I’m new to all of this including being a first time mom/in-home daycare owner and have lots of questions lol! Thank you in advance for your time, patients, and wisdom! 🙂

You could potentially transfer it! We did not. You wouldn’t add soil to the jar though. Makes a great experiment to see if it takes outside or in a pot!

Seed Germinator

What goes on underground when seeds are sprouting? Make yourself a window into the process of plant development.

• Quick-germinating seeds, such as radish or Wisconsin Fast Plants®
• Paper towel or coffee filter
• Large petri dish with lid, or an old CD case with clear sides (if you’re using a CD case, open it and remove the plastic insert that holds the CD, being careful not to break the case)
• Lidless, straight-sided plastic container wide enough to set the petri dish or CD case inside, on its edge, as shown in the photo
• Two rubber bands big enough to fit around the open container
• Metric ruler with millimeter markings
• Magnifying glass

• Soak the seeds overnight in water.
• Set aside the top of the petri dish, or open the CD case. Cut the paper towel (or coffee filter) to fit inside.
• With a ruler and pencil, draw a straight line across the middle of the paper towel. Lay the marked-up paper in the bottom of the dish (or inside the CD case) so the line sits horizontally across the center. If you’re using a CD case, be sure the hinged edge is at the top or side (not bottom).
• Pour a little water into the dish to wet the paper towel. Smooth out any bubbles and tip out any extra water not absorbed by the paper. Later, when you stand the dish on its edge, the wet paper should remain stuck to the inside of the dish or CD case.
• Place 6 to 10 seeds on the paper towel, evenly spaced along the reference line. Then put the lid on the petri dish, or close the CD case.

• Pour water into the container to a depth of about 1 inch (2 to 3 cm). The water should seep into the petri dish or CD case and contact the paper towel, keeping it moist as the seedlings begin to sprout.
• Put your seed germinator in a warm place (room temperature or slightly higher), away from direct sunlight.

Check on your seeds once or twice a day, and notice what changes or emerges (see photo below). (It’s fine to open the seed germinator; just handle it carefully so the seeds don’t move.) Do shoots with green tips emerge first, or do white roots emerge first? Do each seed’s roots and shoots sprout in the same direction, or in different directions? Use a magnifying glass to examine the growing structures in more detail. How do they change over time?

Measure the growth of the roots and shoots over time. You may want to collect data to graph average root length vs. time, and average shoot length vs. time. (Note that it’s helpful to measure time in total elapsed hours, rather than days.) Which grows faster, the shoots or the roots?

Inside a seed is the embryo of a plant, plus a food source for that embryo, all contained within a protective seed coat. Here, you can observe seed germination, in which the embryo begins to digest the food and grow into a seedling. While this process usually happens in soil, the key component for germination is water.

At appropriate temperatures, most seeds begin their germination by absorbing water through a tiny hole in the seed coat. The moisture starts the metabolic processes of the embryo that’s contained within the seed. When hydrated by absorption of water, enzymes in the seed are activated. They begin digesting the food stored inside to generate energy for the embryo’s growth.

The developing root emerges from the seed first. As the root grows longer and thicker, it develops tiny root hairs, which help the developing plant take up water and nutrients. Shoots with pale-green leaflike structures emerge after the roots. Eventually, these leaves will turn a deeper green color and begin to photosynthesize, capturing and storing light energy and carbon dioxide from the air.

Photosynthesis in leaves supplies the plant with the energy and matter it needs to grow. Newly germinated seedlings, however, are not yet photosynthesizing. Instead, in early stages of growth, the embryo digests and assimilates the energy and matter from the food present in the seed. Depending on the type of seed, this food store contains a mixture of proteins, fats, sugars, and starches. This stored food isn’t just important to the developing plant embryo; it’s also important to human diets. About 45 percent of the calories humans consume globally comes from seed grains like rice, wheat, and corn.

A common misconception is that plants get their mass from soil. In this soil-free experiment, you can prove to yourself that plants don’t strictly require soil to grow. In fact, many plants grow very well hydroponically in water cultures, as long as the appropriate nutrients such as nitrogen, phosphorous, and potassium are provided. Your seedlings will eventually need more space than the seed germinator can provide, but given the right lighting conditions, they’ll begin to photosynthesize, accumulating mass from the carbon dioxide in the air and the water you provide.

This seed germinator makes it easy to design and perform experiments to determine the materials and conditions seeds need in order to germinate and grow. The effects of temperature, light levels, and water conditions (such as pH or salinity), as well as the presence or absence of various nutrients are all factors you can investigate. Experimenting with the position and lighting of the seed germinator can help you determine the conditions necessary for roots to grow down, and for shoots to grow up. Do roots sense gravity? Do they sense light? Or are they affected by other factors?

Jennifer Nemhauser (she/her) is a queer and pansexual biologist. She is a faculty member in the Department of Biology at the University of Washington and studies how plants use signaling networks to change the shapes of their bodies to make the best of particular environments. She hopes that if she can learn how plants control division, growth, differentiation, communication, and death, she can help breed the next generation of more resilient crops. Prior to her faculty position at the University of Washington, she completed her doctoral work in auxin and flower development and post-doctoral work in hormone interactions in seedling development. Jennifer feels as though she expresses her queer identity the most in the ways she works to build a distinctly queer scientific culture within her lab group—an effort that is reflected in the large number of LGBTQIA+ students and postdocs that have found a home there. Make yourself a window into the process of plant development with the Seed Germinator Science Snack.

As noted in the What’s Going On? section above, this experiment can be used to begin investigating where a plant’s mass comes from. To do this, weigh the seeds before you soak them. Allow the seedlings to grow under good light conditions for several days, so they begin to accumulate mass through photosynthesis. Then take them out, let them dry, and check their mass again. Comparing the initial mass of the seeds to the dry mass of the germinated seedlings can help show students that a plant’s mass does not come from soil or water.

Germination Science Experiment

In this twist on the classic germination science experiment, children will test the germination rate of 10 green bean seeds. From making predictions to collecting data, your little scientists will learn all about seeds and how plants grow.

Let’s get started with this germination of seeds activity!

An Easy Germination Science Experiment for Kids to Do

A fun way to teach your child about the germination of seeds!

Materials Needed for Germination Science Experiment

• Plastic baggie
• Black permanent marker
• Paper towel
• Spray Bottle

Directions for Germination Science Experiment

Before the germination science experiment read seed books and talk about seeds.

Introduce the word GERMINATION.  Germination is when the seed begins to grow a root and a shoot. This experiment will allow children to see how and how many seeds germinate.  The plastic bag acts as a window into the world of plant growth!

• Fold the paper towel so it will fit neatly inside the plastic bag.
• Using a black permanent marker, draw a 10 frame on the bag.
• Fill the spray bottle with water and let children mist the paper towel until it is completely moist.
• Place the wet paper towel in the bag.
• Have the children place one bean seed in each compartment in the 10 frame.
• Close the bag and set it flat near a window or other sunny area. (the bag can be taped to a window, but the seeds do not stay in the 10 frame well!)

Discussion Questions for Germination Science Experiment

Do you think that all 10 bean seeds will germinate? Explain your answer.

MATH CONNECTIONS:

• Write a prediction on how many bean seeds you believe will germinate.  You many guess numbers between 0 and 10. After plants have germinated check your predictions.  Discuss the results.
• Can you figure out the percentage or germination rate of your bean seeds?  Take the number of bean seeds in your bag that germinated.  Use a calculator and times that number by 10.  If 8 seeds germinated, you would take 8 x 10 = 80.  Your seeds would have an 80% germination rate.

Why do you think knowing a seeds germination rate would be helpful to a farmer?

NOTE: Bean seeds germinated in this way “may” grow if you place them in a soil garden area shortly after germination begins. Often teachers will allow the bean plants to continue growing until leaves form so that students can see the plants growing.

Bean Seed Germination Experiment

Facts about Beans

• A bean seed will grow into a bean plant.
• The plant will produce blossoms that will turn into beans.  If left to mature. The beans will contain 5-6 bean seeds that can be re-planted.
• Some bean seeds are white, red, brown, or black.  We have even planted red speckled bean seeds.
• The roots and stem will come out of the seed.  When this happens, it is called – germination.
• Roots go down from the bean seed into the earth due to gravity.  They help the bean plant absorb water and nutrients from the soil.  You will see this in the first few days of your grow a bean maze experiment.
• Even if you plant the seed upside down, the roots will “turn themselves” back the right way.
• The stem, or shoot, will go upwards in search of sunlight and air.

Germination Science Experiment Vocabulary

Germination :  when the seed begins to grow a root and a shoot.

Root :  Part of the plant beneath the soil that absorbs water and nutrients.

Sprout : the beginning growth of a plant

Sprouting : the practice of germinating seeds

We all know that plants need water, sun, and soil to grow. In this science experiment, kids will grow a bean maze to truly “see” how plants will seek out what they need.
