Bring the 2nd Law of Thermodynamics to life.

Ball and Ring Apparatus demonstrates thermal expansion.

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

Effective Method of Showing Normally Invisible Currents

Brass ball mounted on brass rod for thermal expansion experiments.

Bimetallic strips attached to wooden handle to study thermal energy.

This is a classic example of thermodynamics in action.

Simple Calorimeter to Measure Heat in Many Applications

The movement of liquid currents due to differences in temperature is demonstrated by introducing dye into the water in the tube. One corner of the tube is heated and the movement of the dye clearly establishes the currents. The rectangular shaped tube measures 15×21 cm and has an opening at the top.

Understand Color and Heat Absorption.

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.

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

Demonstrate the Force of Air Pressure Without a Vacuum Pump

Ideal for demonstrating that vapor pressure increases when temperature increases.

Laminated for long use.
