This activity illustrates the relationships of mass, potential energy, and kinetic energy with marble races.

Use a calorimetric technique to determine the temperature of a Bunsen burner flame.

Use a clever apparatus to determine the coefficients of thermal conductivity of three materials.

A set of four borosilicate glass tubes of different shapes connected together to illustrate that liquids will stand at the same level.

This working model thermostat will demonstrate how differential expansion is used to control temperature. A bimetallic strip is used to open or close an electric circuit when temperature changes. The contacts will carry about three amperes. The unit can be operated with a 6 V lantern battery, low voltage power supply, or a blow dryer. Mounted on a metal base; approximately 15 cm high.
