Confessions: Watch It Grow
Spring Science Experiment
Watching seeds grow is an amazing science lesson for kids. Our watch it grow experiment gives kids the opportunity to see up close how a seed grows what would actually be happening under the ground! Our awesome seed growing activity turned out amazingly well, and we loved checking on the progress each day.
HOW A SEED GROWS
This simple to set up seed jar was one of our favorite spring science projects that you can do inside. We had an awesome time examining and observing the growth of our seed germination experiment.
Beginner science can be a wonderful experience that introduces young kids to the world around them. Spring is full of new beginnings in nature that can be explored.
Share an inside look at how seeds grow below the ground with our seed jar. Plus, you can even get it started when there’s is still snow on the ground. Especially if you are itching for spring to come early like I am.
It all starts with a single seed.
It’s truly amazing to watch 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.
I first saw this awesome seed germination activity done by How Wee Learn. Looking around my kitchen, I had everything I needed to set it up immediately! It looked like an awesome way to see how a seed grows, so we got it started right away.
What you need:
- Paper Towels
- Seeds (Pea and bean seeds grow quickly)
- Large jar
We also enjoyed the book, How A Seed Grows by Helene Jordan which inspired another seed activity with eggshells (coming soon)
What you do:
Our mason jar includes sunflowers, peas, and green beans
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.
BEAN SEED GERMINATION
This type of activity makes a great plant science fair project for multiple ages. Get your magnifying glass out and check out all the angles of the seeds. Can you find the different parts of the seed growth listed below?
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 root to push down into the soil.
- Then, you are looking for root hairs.
- Next, you are looking 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. Do you know you can also grow crystals in mason jars for a fun science activity… BOOM SCIENED
SEED GERMINATION IN THE CLASSROOM OR AT HOME
Setting this up as a science experiment is a great way to share the activity with multiple ages or developmental levels. Older kids can use a science experiment worksheet to journal about how the seeds are growing while younger kids can draw or simply observe the changes.
SEED EXPERIMENT VARIATIONS
You can also 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 to investigate is 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 GERMINATE SEEDS FASTER
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.
We started this experiment on March 15th and within a few days started to see some exciting things. It was also interesting to talk about what was happening with the different seeds and how they changed over the duration of the experiment.
Sunflower seeds were the fastest to pop a root but never made it out of the jar.
Bean seeds took the longest to pop a root but finally did and made it out of the jar.
Pea seeds grew rapidly once the root popped out and grew the tallest.
Simple beginnings with the sunflower seeds. Then the pea and lastly the bean. It took about three days to see some action with the seeds.
Amazing to see the pea take off in the seed jar once the root popped out!
My son enjoyed telling me about the root hairs he could see every day. It was really fun to see it flourish and to check out the results. It’s a perfect spring science activity at home or even in the classroom.
Boom DONE! Let me know how it works for you!
