Three cute activities introduce youngsters to seeds and roots. In the first activity, various soaked seeds are placed in a glass so that the direction of root growth can be observed. In the second, a bag of seeds is filled with water and left to sit overnight. Make sure to place it in a pan or bucket since the seeds absorb the water, expand tremendously, and burst the bag! Finally, seeds are planted in plaster to show that the roots can actually break it up as they grow.
