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.

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.
