Spring is a wonderful time of flowers blossoming, new plants sprouting and life popping up everywhere! But when you see plants just beginning to grow, have you ever wondered what’s going on beneath the soil? The leaves, stems and flowers we see above ground are just the beginning!

 

But how can we catch a glimpse of what growing plants hide underground? This easy and fun science experiment to try at home will reveal all! You will need: a clear container like a mason jar, some wet paper towels and a few seeds. Try sunflower seeds or any kind of bean to get quick results.

 

Fill the jar with wadded up, wet paper towels, then carefully slide a few seeds down the sides of the jar so that they are trapped between the paper towels and the sides of the jar. Make sure your seeds are fully visible.

 

Place the jar in a sunny spot like a windowsill, and check on it every day. Keep adding just enough water to keep the paper towels from drying out.

 

In a few days, you’ll start to see something happening. The seeds should look like they’re getting fatter, and there may be a plant structure starting to poke out. Can you explain what you’re observing? What’s causing the seeds to begin sprouting now?

 

First, you’ll see a root grow out of the side of the seed. As the root grows longer, it will push down toward the bottom of the jar and you’ll begin to see some fine root hairs start to grow sideways out of the main root.

 

Then as the root moves down and pushes the seed up, the seed will begin to sprout shoots that will become leaves. When you’ve got leaves, your seed has become a seedling and is ready to be planted in a pot or in your garden.

 

Once planted in soil, the root and root hairs will continue to grow and provide structural for the seedling as well as water and nutrients as the seedling develops into a plant. Now you know what’s happening under the soil as well as above it!
