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.
Used to simulate effect of earth's rotation on winds, ocean currents or unattached objects such as rockets. As sphere is launched across surface of base, when it is static, sphere traces a straight line. As turntable is put in motion, centrifugal force launches the sphere which, though traveling in a straight line, leaves a curved trace on rotating surface. Size of curve is in direct ratio to speed of rotation. Each kit includes one 14" diam. base (with outer retaining trough) mounted on a turntable, and featuring a reusable "magic slate" type erasable trace recording surface, removable launcher, 5/8" diameter steel spheres.
