Additionally you can graph how many children think their seed will grow and how many will not. Graph their prediction and their results. Put a white carnation in a cup of colored water (darker color the better) and let your kids see how flowers drink water (the flower will take get its color changed as it takes in the water) Take knee high hose, sprinkle grass seed in the toes then add potting soil to make about a baseball size.
