Last week we were introduced to the idea that things can change on the earth, and that these changes can happen slowly or more quickly. One way to explore how the earth is always changing is to look at rocks. Today we answered the question: How are rocks alike and different? As this unit progresses, we will learn the technical terms for different types of rocks, as well as begin to look at weathering and erosion. I can't wait.
See some pictures below of the students collecting rocks and then making and recording observations.
