|Observing rocks and what makes rocks.|
|Taking the rock apart by identifying the minerals in granite.|
Our rock unit is a hard unit for third graders to grasp all of the concepts. I find that exposing them to rocks as much as I can helps students see the properties that rocks have. We use the rocks several ways. We look at them for different reasons each time we get the rock specimens out.We use different tools to take this sample of granite apart. We have granite sand from the Upper Peninsula of the great state of Michigan. We have feldspar, mica, quartz and hornblende that make up this rock we call granite. We have magnifying glasses, tweezers and toothpicks to observe and separate the rocks.
