Product Description
This fun-filled lesson encourages students to explore the properties of minerals. Students will explore the property of hardness by performing a scratch test. In this lesson students will identify a mystery mineral using only its physical properties. This will prove hard to do when the specimens are of similar color. In this lesson students will begin to see the value of determining the hardness of a mineral specimen. Students will be introduced to the tools used to perform a scratch test (fingernail, copper penny, steel nail, and paper clip). Students will perform a scratch test on four mineral samples (fluorite, gypsum, calcite, quartz). Included in this resource is a comprehension passage on Hardness.

RESOURCES:
