Wool food web

Students link species with wool into a web of connections and see what happens when one disappears.

Steps

1. Each student gets a card with a meadow or woodland organism.
2. Pass the ball of wool along, linking who eats whom or who helps whom.
3. When the web is complete, one species lets go of its thread.
4. Watch who felt the change and talk about the consequences.

Tip: Add species from your local area; students will be more engaged.

Materials needed
