Worm Introduction



Students will understand that worms help to make soil through digesting organic matter. Students will see the process from beginning to end through the worm bin/apartments.


Where does soil come from? What do worms need to survive?


Worm bin/apartments, Shredded paper, Watering cans/spray bottles, Finished worm castings, Food scraps, Gloves, Plastic spoons or tools for digging through worm bin


Ask the class: “Where does soil come from?”
“How do you think worms can help us make soil?”
Brainstorm a KWL sheet about worms (I Know-I Wonder-I Learned).

Activity: Set up different stations for students to do scientific observations
1) Worm bin – Bins of finished worm castings. Students can scoop out finished worm castings into another container or into the watering can for compost tea
2) Worm bin – empty bins. Students can fill the empty bins with food scraps and shredded paper.
3) Worm observation – Students can take a good look at worms, their sizes, shapes, movements, etc.

Wrap up/ Assessment: Each student shares one observation from the worm bins – one thing they didn’t know before. Add to the “L” column of the KWL sheet.
