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

This new conductivity bar set features sensitive liquid crystal temperature indicators, which are attached to the front of each of four metal bars.

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

Students Can Simulate the Earliest Steam Engine.

Ideal for demonstrating that vapor pressure increases when temperature increases.

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.

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

This diver set expresses the effects of air pressure and buoyancy.

Visually illustrate the difference in specific heat.

High quality linear expansion apparatus to study thermal expansion.

Brass ball mounted on brass rod for thermal expansion experiments.

Bimetallic strips attached to wooden handle to study thermal energy.

Radiometer with four lightweight metal arms.

Ideal for studying heat and thermodynamics.
