Discover the science of plants with this innovative self-watering greenhouse. Add soil, water, sunshine, and curiosity to grow a sunflower, a plant that is sensitive to touch, and a bean. Water the plants using the drip-drop watering system, and chart the growth of each plant by filling in the Seed Growth Chart as the seeds sprout and grow. Read the booklet included in the package to discover the answers to scientific plant questions such as how plants defend themselves and why people need plants to live. When the plants have outgrown the mini flowerpots, learn how to transplant them into the garden and then choose new seeds to grow.
