Do Earthworms Like Light Animal Science Experiment
In this fun and easy animal science experiment, we are going to investigate earthworms and try to determine if they like light.
Earthworms (You can often find these under rocks in your yard or you can purchase them at a bait or pet shop)
- Desk lamp
- Paper towels
- Box or plastic tub
- Cover up half of the box with a piece of cardboard, book, or some other item that will not allow light to pass through. If you are using a shoebox, cut the lid in half.
- Fold up several paper towels. Make a layer out of several sheets and place it in the bottom of your container.
- Wet the towels so they are nearly saturated.
- Gently place your earthworms into the container. Space the out evenly and try to make sure they are not touching.
- Return the cover to your container if you removed it while placing the earthworms inside.
- Place the desk lamp nearby and turn it on. Make sure it is one to two feet above the top of the container.
- Do not disturb the container for fifteen to twenty minutes.
- Observe where the earthworms have ended up.
How it Works:
By creating an area with light and dark sections, you provide the earthworms an opportunity to essentially make a choice of which area they prefer.
Make This A Science Project:
Try leaving the paper towel in the dark side dry to see if this effects the earthworms preference on where to move. Try different temperatures of water on the paper towels, making sure not to make the temperatures too extreme to avoid injuring the earthworms.
