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.
✅ Task Card instructions
✅ Student Sheets for capturing observations
✅ Answer Keys to Student Sheets
✅ Teacher Notes with prep, set up, and explanations.
This Resource Is Great For:

☀ How can you determine which rocks are magnetic?
☀ What rock(s) react to acid by fizzing?
☀ How do different rocks appear under magnfication?
Topics & Concepts Addressed:
✦ When studying rocks you can compare their grain sizes.
✦ A few rocks are magnetic
✦ Limestone and chalk react to acid by fizzing.
suggested rock and mineral samples: granite (fine and coarse-grained), basalt, soapstone, mudstone, siltstone, gabbro, breccia, conglomerate, schist, gneiss, obsidian, halite, quartz, amethyst
collect materials, order rock samples
Answer Keys and Teacher Notes address most questions and issues that might arise in this study—you shouldn’t have to do any outside research unless you want to.
