This site provides an activity on the conductivity and resistivity of various materials. A thermometer and other everyday materials like wood, metal, and styrofoam are used to compare temperatures detected by one’s...

This demonstration provides an aesthetic way to view convection currents in fluids. Water warmed by an electric circuit mixes with the surrounding cooler water creating turbulence effects that bend light; the resulting...

This article by Paul Doherty, Senior Scientist at the Exploratorium in San Francisco, describes the burning peanut experiment and provides an introduction to food energy and how it is measured. The site presents an...

This site from the Exploratorium provides a demonstration of how heat can destroy magnetism. The site contains a materials list, assembly instructions, and basic procedures for the activity. Also presented is an...

This Exploratorium activity uses dipping birds to provide an introduction to heat engines which convert heat energy to mechanical work. The site contains an explanation of the physics involved and also an extension...
