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.

Simple Calorimeter to Measure Heat in Many Applications

Students Can Simulate the Earliest Steam Engine.

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

Ideal for demonstrating that vapor pressure increases when temperature increases.

Laminated for long use.

Ball and Ring Apparatus demonstrates thermal expansion.

Employs Guericke’s Method for Demonstrating the Force of Atmospheric Pressure.

Sized For Student Use.
