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.

This vacuum plate and pad are the perfect tools for vacuum experiments.

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 Specific Heat Specimens Set can be used to determine the specific heats of a variety of common metals.

Effective Method of Showing Normally Invisible Currents

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.

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

Bring the 2nd Law of Thermodynamics to life.

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.
