To go along with the book "The Tiny Seed" plant sunflowers. Plant the seeds in tiny plastic cups with soil (or plastic bags with moist towels) as the seed grows you can show your children how the roots form in the soil and the plant grows above the soil.
Additionally you can graph how many children think their seed will grow and how many will not. Graph their prediction and their results. After reading the "The Very Quiet Cricket" get several crickets from a bait shop and let your children watch them make noise. Once your children have seen them take them outside and set them free.
