The 9-title Wonders of Physics and Chemistry series covers everything from the definition of an atom to the science of light. Students can start to develop basic understandings of the fundamentals of science, then work their way up to more complex subjects. Each program includes a subject specific teachers guide which includes subject matter revision and suggestions on how to present material, questions to ask students, and class projects to help illustrate the key concepts. Matter is anything that has mass or takes up space. Three of the recognized five states of Matter are solid, liquid and gas. (The other two are plasma and Bose-Einstein concentrates) As different forces are applied to matter, like heat, matter can change from one form to another: solid to liquid, liquid to gas, or solid to gas. Show Me Science: States of Matter: Solid, Liquid, and Gas describes what happens to matter at boiling, melting, freezing, and dew points. The program also explains suspensions and solutions, as well as how these are taken apart.
