STC Literacy Series™: Chemical Tests

What do an ice cube, water in a glass, and clouds in the sky have in common? They all hold the compound we call water. Everything around us, all the stuff or matter in our world, is made of chemicals. Chemical Tests, part of the STC Literacy Series™, introduces the science of chemistry using accessible, real-world examples. Learn about the properties of chemicals in our world, how we use chemicals to make our lives better, and compare natural chemicals to chemicals made by humans.
