Down and Dirty is a science project that teaches kids about all the creatures that live in the dirt. Soil contains microscopic animals that breathe.
What You'll Need:
- Garden soil
- Jar with a lid
- Limewater (available at a drugstore)
- Small container
How to conduct the Down and Dirty experiment:Step 1: Drop a large handful of garden soil into the bottom of a big, empty jar. Pour some lime-water into a small container. Note what the lime-water looks like.
Step 2: Set the container of lime-water, uncovered, inside the large jar so it rests on top of the soil. Tightly screw on the lid of the large jar, and leave it undisturbed.
Step 3: In 2 or 3 days, look at the lime-water to see if it has changed in any way.
