Today students tried their hands at being geologists! They examined and described ten different rocks, and then used those observations to attempt to classify them as igneous, sedimentary, or metamorphic rocks. After this first attempt, based on their observations and prior knowledge, they used illustrated information sheets to do research on how and where different rocks are formed. They then revised their classifications, identified the rocks, and presented their reasoning to their classmates. We had some good discussions as students thought about the processes that can turn one rock into another, in the never-ending Rock Cycle.
See if your student can find an example of one of the rocks we studied next time you’re walking around outside – many specimens were examples of very common rocks!
