This Crushing Test lesson plan also includes:
Solidify understanding of the properties of crystals by crushing them to compare hardness. After some class discussion, a procedure is planned, and then small groups go about making observations as they crush five different crystal samples. This is the second in a short series of lessons about physical properties of solids and is really only pertinent when taught in conjunction with the others.
- Comes with a solid lesson plan and a copy of the entire matter investigation unit
- Strong scaffolding when used with the other lessons in the mini unit
