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 studying heat and thermodynamics.

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.

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.
