Given eight mineral unknown “suspects,” students are challenged to identify each mineral by name. Student “detectives” gather evidence about the eight unknown mineral specimens by performing numerous laboratory tests including observation, light interaction, streak, mineral hardness, cleavage, smell, ice, and solubility. Students then use the “clues” and properties gathered to identify each mineral by name.Reproducible student laboratory sheets and teacher notes with sample data are included. Kit contains 15 sets of mineral testing chips, 1 large teacher display set of each mineral, 15 Observation and Evidence 11" x 17" data tables, and all the specialized materials needed to perform this lab. Note: Extra halite and calcite testing chips are available separately, as these are the minerals that will dissolve in the solubility tests.Complete for 30 students working in pairs.
