Review & Description
Minerals are naturally-occurring, solid substances composed of chemical elements. This means that minerals, ranging from salt to rubies, are made up of compounds of elements that appear on the periodic table. Each type of mineral has a specific chemical composition and consistent physical properties. They are inorganic, not living or made up of living things. Minerals form crystalline structure, which give their rough texture. A rock by comparison is a naturally occurring solid aggregate of minerals. Rocks and minerals are fun to study because there is so much variety in colors and crystals. The Mineral Science Kit is a great way to start your study of mineralogy. Whether you're a student learning geology, or a rock hound by hobby, this kit is a great way to learn about minerals. An awesome educational toy for the science classroom! Includes: * Instructions and Mineral Identification Key: Provides instruction identifying common minerals. * Mineral Specimens: The 15 specimens in this kit are examples of common minerals that have distinct physical characteristics. You can perform tests to identify them and check your results with the included key. Then you'll be ready to identify specimens of your own. * Magnifying Lens: This is one of the most important tools for a mineralogist, because identifying minerals involves close observation. * Nail: A nail is one of the many common items you can use to test the hardness of your specimens, along with a fingernail, penny, and piece of glass. * Streak Plate: A streak plate is used to determine the color of a mineral in powder form. Warning: Choking hazard due to small parts. Not for children under 3 years old. Box Size: 7.25in (18.42cm) x 5.00in (12.70cm) x 1.50in (3.81cm) Recommended for ages 8 and older. Read more
