Earth Materials Unit

We opened up our unit on Earth Materials with "Mock" rocks. Yes, these are homemade rocks!

The students measured them, weighed them, and took them apart!

We learned that rocks are earth materials made up of more than one ingredient. Our job was to separate all the different ingredients that made up our mock rocks!

They found red and green gravel, shells, and lots of powdery material.

We wanted to see if we could separate the powder material anymore, so we added it to water. We did a lot of shaking before we let it settle overnight.

Shake! Shake! Shake!

You will have to ask your child what he/she observed the next morning!
