Crushing Test

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.
