Tuesday

We learned about different types of rocks today. We got out a rock collection and the students were able to compare granite and gneiss, pumice and obsidian, sandstone and marble. We learned that the rock cycle can go many different ways and that what really makes rocks are other rocks. Then the students used the streak test on the rocks.

Tomorrow we will review Mohs hardness scale. Please make sure your student realizes that school doesn't end until the 29th of May. We still have a lot to do and books, paper and pencils are all required.

Tomorrow morning is the school talent show. Homework is to finish reading section D.
