Demonstrating processes of the earth can be a valuable way for showing students things that take place over a long time. This “Rock Sandwich” science lab helps students to visualize the process of sedimentary rocks turning into metamorphic rocks.
This is an amazing unit on studying rocks and soil. Totally hands-on. They make a rock museum, float pumice and sink other rocks, describe their rocks in their science journals, sift soil, there are printables about what we use rocks for that can go right in the journals. Love this!
