PIRA Code(s): 3D46.15
Set up time:1 minute
Operation: Hit a tuning fork with a striker to produce a sound wave.
Physics and Science Concepts: Oscillations and Waves
Safety: None

PIRA Code(s): 3D46.16
Set up time:no setup required
Operation: Place the boxes with open cavities facing, one box length apart. Strike the first tuning fork with the striker. Stop the vibrations with your hand. Listen closely for the sound coming from the second fork.
Physics and Science Concepts: Waves and Oscillations
Safety: None

PIRA Code(s): 5A50.10
Set up time:2 minutes
Operation: Place the four (two large, two small) balls on the poles in the front about 1 inch apart. Turn the crank.
Physics and Science Concepts: Electrostatics
Safety: Do not touch any metal portions of the generator

PIRA Code(s): 5A50.30
Set up time:10 minutes
Operation: Plug in the generator. Turn on the rocker switch and adjust speed using potentiometer on the base of the Van de Graaff.

Other suggested uses include combining this with other electrostatic demonstrations found under a 5A50 heading. Also, throwing packing peanuts or taping strips of paper to the Van de Graaff are popular demonstrations.
Physics and Science Concepts: Static Electricity, Friction
Safety: The rod works best on dry days with the blue wig. Care should be taken when operating. Do not approach the generator while it is running. Use the grounding rod to discharge.
