Three different labs to investigate rocks and minerals. In the first, kids will compare various rocks in terms of their grain sizes. In the second lab, kids will test rocks for magnetic properties, and lastly they’ll see how chalk (a rock) reacts to acid by fizzing. Each of these activities model procedures that geologists do.
