Ball and Ring Apparatus demonstrates thermal expansion.

Sized For Student Use.

This unit visually reinforces heat conductivity lessons.

Ice Melting Blocks are a unique way to teach principles of conductivity of heat and the scientific method.

A new way to demonstrate thermal expansion in a metal.

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.

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

The Precision Linear Expansion Apparatus produces accurate determinations of the coefficient of expansion.

Bimetallic strips attached to wooden handle to study thermal energy.
