Rock Investigation in Class 4

Class 4 spent some time this week investigating different types of rocks, as a part of our IPC Unit: What a Wonderful World. We practiced making observations, creating hypotheses, recording data in charts, and drawing conclusions about three very different rocks.
Students loved taking measurements of the rock’s weight using a digital scale. We finished our discovery of types of rocks by leaving one of each in water overnight. We found that they each increased in weight, then had to make some inferences about why!
Next time you see a rock, ask yourself: is it igneous, sedimentary, or metamorphic? You might be surprised!
