Follow the link above to start or download this activity.

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 explore how the Law of Conservation of Energy (the First Law of Thermodynamics) applies to atoms as well as the implications of heating or cooling a system. This unit focuses on potential energy and kinetic energy as well as energy conservation. The goal is to apply what is learned to both our human scale world and the world of atoms and molecules.

Students will be able to:

• Differentiate between kinetic and potential energy.

• Explain how kinetic energy can be converted to potential energy and vice versa.

• Analyze energy graphs and the motion of objects in a system to learn about the Law of Conservation of Energy.

• Apply the first Law of Thermodynamics when heating or cooling a system.

• Differentiate between energy transfer in an open system and energy conversion.

Benchmarks and Standards

NSES

  • Physical-Science: Energy Conservation / Entropy - 1 The total energy of the universe is constant (Full Text of Standard)

  • Physical-Science: Energy Conservation / Entropy - 2 All energy can be considered to be either kinetic energy, which is the energy of motion; potential energy, which depends on relative position; or energy contained by a field, such as electromagnetic wave (Full Text of Standard)
