The students are continuing to bring in their rock collections. It is very fun for all the kids to see the collections and what they mean to their classmates. If your student hasn't started a collection yet please remember that found rocks are great and you do not need to buy any thing. When your student has at least 12 rocks they should bring in the collection to share.
We learned about mineral hardness and how to test the minerals using simple tools, ask your student how to do it. The 4th graders will be taking their first test this week and you should receive them back through the classroom teacher next week. We are moving on to the "acid test". We will be using vinegar to test for calcite. You could do this at home with any old rock, all the students will know how to do this by the end of the week.
