Physics Central – Learn How Your World Works — from the Free Technology for Teachers blog

Physics Central is produced by the American Physical Society for the purpose of educating the world about physics. Physics Central is divided into four main sections; Discover, Explore, Ask & Experiment, and Physics Buzz. It is the Ask & Experiment section that is probably of most interest to teachers. In Ask & Experiment teachers will find coloring and activities books for students. Ask & Experiment also includes an “ask a physicist” section in which students can ask questions or find the answers to roughly 100 previously answered common questions such as “why do ice cubes sometimes stick to your skin?”
