Preschool Science: Worm Farm
Preschool-aged children love to play with worms (at least my boys do!). You can turn their curiosity with worms into a science project with just a few items from your house and garden. Here is what you’ll need:
Empty two-liter pop bottle
Exacto knife
Dirt
Small shovel
Sand
Grass clippings
Kitchen compost (apple peelings, etc.)
Worms
Before you let your child loose in the garden, you will need to use the exacto knife to cut off the entire top of the pop bottle.
Help your child create a label for the container that has the child’s name and “worm farm” printed on it. You can make it by hand or on the computer. Tape the label to the front of the container.
Go out to the garden with your child and let he or she shovel a couple of inches of dirt into the plastic container. Pat the dirt down so the next layer of sand won’t filter through. Explain to your child that they need to be careful not to shake or jar the bottle or the sand and dirt will become mixed up.
Add a thin layer of sand, and then continue with a couple of inches of dirt and another thin layer of sand. The top layer should be dirt. Leave an inch or two of space at the top of the bottle.
