Earthworms also night crawlers, move though the earth by lengthening the front of their segmented bodies, then contracting the backs. They live under ground where we cannot see them, but if you make this wormery, you can observe the way earthworms crawl.
The materials you need to properly perform this project are a jar, soil, sand, garden spade, 2 or 3 earthworms, leaves, rubber band, black construction paper and cellophane tape. The purpose of this experiment is to determine how long it takes for earthworms to make their tunnels. I believe that the earthworms will have their tunnels every were in less than four hours. .
To complete this project I find a large empty jar that is clean and dry. Put a layer of damp soil into the jar. Then add a layer of clean sand. Fill the rest of the jar with more damp soil. In your back yard or a nearby field, dig up a patch of earth with a garden spade. .
See if you can find two or three earthworms. It is easiest to find earthworms in damp, warm soil, so you might want to look for them after a hard rain. Collect a few leaves, too. Put the worms and leaves on top of the soil. .
Stretch a piece of cheese cloth over the top of the jar and hold it in place with a rubber band. Wrap a large piece of black construction paper around the jar. Fix the seam firmly with cellophane tape. Leave the jar in a safe place. After a few days, take the black paper off. In my conclusion I was right about the worms having their tunnels every where. .
