Mineral Formation and Identification Kit
15480

Introduce your students to the world of minerals. Provide your class with a hands-on lesson in the formation and characteristics of minerals. Using the set of specimens provided, the students observe the distinct characteristics of minerals and perform a variety of tests to classify them with respect to hardness, streaking, color, luster, specific gravity and reaction to acids. They'll also grow their own microcrystals to understand how crystals form beneath the earth's surface and what environmental conditions are required. Your students will identify minerals based upon their physical properties. Determine the hardness of common minerals using Mohs scale of hardness. Examine the crystalline structure of minerals. Calculate the specific gravity of mineral samples. Predict the reaction of specific minerals to hydrochloric acid. Investigate how crystals form from liquids. Class Size: 40 Students. Grades: 7-10.
