Thermal expansion of different metals.

Sized For Student Use.

A fascinating demonstration!

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

This unit visually reinforces heat conductivity lessons.

The Student Coin and Feather Tube shows the two items in a vacuum, falling at the same rate.

This apparatus is useful for studying forces during thermal contraction and expansion.

Teach students how heat travels!

This polished copper calorimeter set has everything you need.

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.
