This classroom rocks and minerals collection provides students with hands-on experience testing physical properties. The collection and materials are designed to correlate with standard earth science texts, and can be used for demonstrating the physical properties of minerals, including hardness, specific gravity, luster, tenacity, cleavage, fracture, streak, and magnetism. The collection includes 75 rock and mineral samples (measuring approximately 1-2 ), a streak plate, a magnifier, a collection index sheet, and a study guide (with rock classification and rock cycle charts). The samples fall into 1 of 7 categories- minerals in the scale of hardness, streak-luster-cleavage-fracture-specific gravity, rock forming minerals, ores of metals and nonmetals, igneous rocks, sedimentary rocks, and metamorphic rocks. This collection is great both at home and in the classroom, designed for grades 4-12. Science education products incorporate applied math and science principles into classroom projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology.
