Students will discuss how animals (worms) can help the Earth and people. Students will be introduced to a compost bin and observe live worms in their habitat to investigate how worms can be helpful.
Worms help turn our leftover food into nutrient-filled soil. After the worms digest the food scraps, they leave their manure, called castings, in the soil. Their castings are filled with nutrients that can help plants grow. Without worms, the soil would not be as healthy and plants would have more difficulty growing. Without plants, animals and people wouldn’t have food to eat. Tell your students you are going to build a home for worms and keep the worms as helpers in your classroom. The worms will recycle food waste into fertilizer for a garden. (Worms help plants grow, and people eat plants.)
