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

This model starts with a crystal consisting of about 300 identical atoms that are held in place by van der Waals forces. You can increase the average kinetic energy of the atoms by clicking the red and blue arrows on the "thermometer." If you heat it too much, you will melt the crystal. You can always start over using the reload button. Experiment with shock waves, thermal memory, and more.

Students will be able to:

  • describe critical variables in the solution of the problem: What causes heat to propagate? How fast does it propagate?
