Carry out investigations to classify minerals using tests for the physical properties of hardness, color, luster, cleavage and streak.
The North Carolina Standard Course of Study, Science (2023) outcome ESS.4.2.1 (Earth’s Systems) for Grade 4 says: “Carry out investigations to classify minerals using tests for the physical properties of hardness, color, luster, cleavage and streak.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: North Carolina Standard Course of Study, Science (2023).
Rocks and Erosion: How Land Changes Shape Grade 4 · partly supports this outcome
Why some rocks scratch and some fizz, how a trickle of water carves a canyon, what keeps a hillside in place, and how a boulder ends up as sand. Four hands-on lessons on rocks, weathering and erosion.
- Are all rocks the same? 50–60 min
Students sort a set of rocks by what they can see, then test them like geologists with a scratch test, a streak test and a drop of vinegar. They use their results to sort the rocks again and back up a claim about which rock is limestone.
