In "Settle for Dirt," kids can see first-hand how sediment is made. When soil, sand, and other materials settle at the bottom of a lake or pond, it is called sediment. Over time, layers of sediment can form rock. See if kids can replicate this natural process with this easy science activity.
What You'll Need:
- Jar with lid
- Small plastic animals (optional)
How to Settle For Dirt:
Step 1: Put a handful each of soil, sand, and gravel into a jar. Fill the jar with water. Put the lid on tightly.
Step 2: Shake the jar well until everything is mixed together. Now let the jar sit overnight.
Step 3: In the morning, see how the different things in the jar have settled. How would you describe what you see? What can you say about the layers? Compare your layers to what happens in a lake or pond.
Step 4: If you want to see how fossilized critters are made, put small, plastic animals in with your soil, sand, and gravel mixture.
In the next easy science project, shake a tree and see what falls out.
