Energy Forms and Changes

PhET Team, PhET; University of Colorado

This pair of interactive visualizations allows students to explore basic and more complex concepts around heat conduction, heat capacity and energy transfer. The basic simulation demonstrates how heating and cooling iron, brick, water, and olive oil adds or removes energy from a system and transfers between objects. At the more advanced level, the systems simulation allows students to see that energy takes various forms, as well as how energy flows and changes from one form of energy into another.

Notes from our reviewers

The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials.

  • This would work well as demonstration or as student use. Easy to embed in lesson on energy forms or transfer of energy within systems. Simulation can be easily manipulated. There is a teaching guide if you create a free account. There are Teacher Submitted Activities that include the simulation. Some are in Spanish. The submitted activities include grade levels from K-5 to college undergraduates.
