This National Aeronautics and Space Administration website explores flames in microgravity. It shows photos of flames in space. Also, it shows a related experiment in which spiral patterns are observed when a slowly...

This lesson introduces students to the basics of nuclear energy production. Topics include radioisotope thermoelectric generators, natural decay of radioactive isotopes, and chain reactions. There is also a discussion of...

This simulation provides a realistic virtual mass-and-spring laboratory. Users can explore spring motion by manipulating stiffness of the spring and mass of the hanging weight. Concepts of Hooke's Law and elastic...

The Annenberg Media organization has created this wonderful new resource for physics teachers, students, and anyone else who would care to learn more about dark matter, string theory, and other "big topics in modern...

The amount of energy used in a home is greatly impacted by the type of materials used in constructing the home. In particular, the thermal conductivity of the materials will affect how quickly heat is allowed to enter or...
