Science: Gems & Minerals

Weeks 22 and 23 of school we learned about gems and minerals using Layers of Learning, year 3 unit 14.

We made cookies without using a recipe. Each ingredient represented a mineral and even though we all had access to the same minerals, each cookie turned out totally different from the others.
