- A large plastic soda bottle (with top part cut off) or other type of clear container
- A piece of black construction paper
- Rubber band
- Four or five earthworms
- Several leaves and other types of worm food (carrot and potato peelings, leafy vegetables, etc.)
- Several magnifying glasses
- Fill the container with alternating layers of sand and soil, making the top layer soil. Moisten the layers so they’re slightly damp (not wet).
- Place the earthworms on a tray for the children to examine using a magnifying glass.
- The children will make observational drawings of the worms.
- Place the worms on top of the soil.
- Add some leaves and or (carrot and potato peelings, leafy vegetables, etc.).
- Tape the black construction paper around the jar. Also cover the top with a circle of paper. Punch a few air holes in the paper that covers the top.
- Place a rubber band around the top to hold the “cover” in place.
- After several days, remove the cover and add a few drops of water if the soil seems dry. Also add some worm food, if needed.
- Wait one week and then remove the construction paper. Have the children draw what they see.
- Release the worms to an outdoor area where the ground is moist and warm.
- Check to see how long it takes for the worms to burrow into the ground.
