Is the ice cooling down the water or is the water melting the ice? Here is a simulation that explores thermal energy transfer with iron, brick, and water. It demonstrates the flow of energy and what happens when each material is either...

A virtual lab to look at the physical features of Earth that affect the amount of the Sun's energy that hits Earth. Students investigate how solar and infrared radiations enters and leaves the atmosphere with this model. Virtual lab...

Explore how heating and cooling iron, brick, and water adds or removes energy. See how energy is transferred between objects. Build your own system, with energy sources, changers, and users. Track and visualize how energy flows and...

View a simulation of water flowing under a wheel that causes the wheel to rotate. Energy from the water is transferred to the wheel.
