The High rpm Steam Engine features an electrically-heated horizontal boiler.

Visually illustrate the difference in specific heat.

This activity illustrates the relationships of mass, potential energy, and kinetic energy with marble races.

Vivid Illustration of Thermoexpansion.

Appropriate for grades 6 to 12 Brings the First Law of Thermodynamics to life! This pair of precision-machined, chrome-plated steel balls is actually a hands-on demonstration in energy transformation. By striking the balls together, you will create enough heat at the point of contact to burn a hole in a sheet of paper.

A set of four borosilicate glass tubes of different shapes connected together to illustrate that liquids will stand at the same level.

Students Can Simulate the Earliest Steam Engine.
