Describes a method to demonstrate induction heating by placing an ordinary mercury thermometer in a high frequency magnetic field and observing the temperature rise. Also describes an ice calorimeter for measuring the mechanical equivalent of heat. (SK)

Describes a set of equipment which can be mounted on magnetic chalkboards or other ferromagnetic surfaces, useful for both experiments and demonstrations in mechanics, including center of mass experiments, and force vector experiments using string, spring scales, weights, and pulleys. (SK)
