DuneCraft's complete classroom kit contains enough materials for twelve students to do several fun and educational experiments. The included planters and lids are made from corn and are 100% biodegradable! Watch the Rocket Plant grow from seed to bloom in less than two months, while the Polka Dot Plants develop multi-colored spots on their leaves. Your students will learn how plants respond to light, temperature, water, humidity, and more. When they are all done, they can even take the plants home!
