It is almost spring and it's a good time to begin looking at plants, seeds and root systems. Two days ago we planted some beans in cotton balls to watch the root systems develop, and they are already sprouting! Later this week I'll add in pictures if they sprout leaves. The tutorial comes from The Imagination Tree, which has lots of great projects. All you need is a jar, some cotton balls and a couple of dried beans. We used a black bean and a black-eyed pea. You don't want the cotton balls to get too wet, so I would suggest measuring out a small amount of water for your child to sprinkle on the cotton balls.
