A very simple, easy and economical way of measuring melting points. The apparatus consists of an aluminum block 2.5" (62mm) in diameter by 2" (50mm) high, with a slanted hole to accept a thermometer. The testing material is sprinkled on the top of the block and the block is heated with a heat source like a bunsen burner. As soon as the material starts to melt the reading on the thermometer is the melting point. This apparatus can be used to measure melting points upto 250 degrees C. Stand and thermometer not included.

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.
