The students took a quiz on the reading and lesson from yesterday. Following the quiz they took notes on Igneous rocks. We then went into the lab and each team tried to find different ways to classify the rock samples. When they were done we talked about the different rock properties, hardness, luster, streak, texture, structure, cleavage and fracture, specific gravity and unusual properties such as magnetism and fizzing when placed in an acid.
Tomorrow we will watch a ppp on the rock cycle and work more with the rock samples. To view the rock cycle click on the rock cycle link and then click on rock cycle overview.
