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.
We identified various minerals.
We tested the various minerals for hardness, scratch, reactive to acid, etc.
We made crystals using borax and also using salt and vinegar.
We watched several YouTube videos.
We went on a minerals scavenger hunt.
We sorted and identified some gems.
