This Activity Requires:

Java 1.5+ - Java 1.5+ is available for Windows, Linux, and Mac OS X 10.4 and greater. If you are using Mac OS X 10.3, you can download MW Version 1.3 and explore within it instead.

Test your system to see if it meets the requirements

Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.

Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.

	Overview and Learning Objectives Students learn that temperature measures average kinetic energy, and heat is the transfer of energy from hot systems to cold systems. They consider what makes a good conductor. Students will be able to: • Distinguish between heat and temperature at the atomic level. • Determine temperature is related to both the speed and the mass of atoms. • Explain that temperature is a measure of the average kinetic energy of atoms and molecules in a system. • Experiment with the amount of energy and the size of a system and its relationship to a rise in temperature. • Compare thermal radiation and heat conduction. return to top
