Number of players:
What you need:
- large plastic bottle
- dead leaves
- food wrap
- dark paper
Cut the top off of a large plastic bottle.
Fill the bottle with layers of soil and sand.
Add 4 teaspoons of water to the soil and put dead leaves at the top of the soil.
Dig around some soil outside and try to find 2 or 3 earthworms and add them to your soil.
Cover the bottle with food wrap and poke some holes in it with a pencil.
Tape dark paper around the sides of the bottle.
Add 2 teaspoons of water each day to keep the soil damp.
After 2 weeks, take the dark paper off.
You should see that the worms have mixed up the soil and made tunnels.
