This lab is a culminating lab activity for a unit on minerals. It requires students to use mineral tests to determine the "mystery" minerals they are given. It is also possible to use this lab as an assessment piece.
Included with the student lab sheet is a grading rubric, a mineral chart for the students to use to identify their minerals and a list of "mystery" minerals to use.
I have the students work in pairs for this lab. Using the list of minerals I place the "mystery" minerals in paper bags and number them. I then have each pair of students write the number of their bag on their lab sheet so that I know what minerals they are working with.
