This week we started a new Science unit called Rocks and Minerals. During this unit we will be learning about;
– the rock cycle
– how to classify and identify rocks (color, lustre, texture, hardness, presence of carbonates)
– how rocks break down to become soil
– ways we use rocks and minerals
We would like to thank Mr. Nicholson for coming in to talk to us about diamond mining! His presentation was a fantastic introduction for our unit. We really enjoyed seeing the pictures that he showed us, and we are excited to learn more about how coal becomes a diamond.
On Wednesday our class also had a Rock Show to show off our rock collections.
As you can see, we had some very interesting and unique samples to show!
Grade 3′s, do you have a favorite rock of your own?
Where do you like to hunt for rocks? Who do you go rock hunting with?
Can you describe the most unusual rock that you saw during our rock show?
