Earth's Minerals
Scientific American Investigates Geology
The polished gems in a beautiful necklace, a countertop, and table salt each have something in common: they're made of Earth's minerals. Readers are introduced to the formation of these minerals through age-appropriate fact boxes and a graphic organizer. Vivid photographs of minerals clarify information about identifying minerals using streak and hardness, allowing readers to further their STEM learning outside the classroom. It is a learning experience that truly rocks!
