Describes how to make an electroscope from aluminum soft drink or beer cans. Also describes several electrostatic experiments using the easily constructed apparatus. (JN)

Describes an experiment on heat that utilizes only a styrofoam cup of coffee and a soda straw thermometer. (BT)

Describes a simple method of measuring the refractive index of a liquid using a paper cup, a liquid, a pencil, and a ruler. Uses the ratio between the actual depth and the apparent depth of the cup to calculate the refractive index. (GA)

Explains how to demonstrate the fundamentals of one dimensional kinematics such as Newton's third law of motion, and collision between bodies, using simple materials of marbles, strings, sticky tape, drinking straws, and rubber bands. (GA)

Describes two simple physics experiments demonstrating the spin on baseballs or golfballs and the observed effects of falling coins when released together. (CS)

Describes experiments, including the measurement of the magnetic moment of a magnet, using noncalibrated materials. Results of these experiments can be checked using calibrated equipment. (SK)
