PIRA Code(s): 2B30.30 Set up time:3 minutes Operation: Place the two halves together. Put the vacuum pump on the valve and evacuate the air inside. Try to separate the pieces. Vacuum pump not included; it must be obtained from demo 3B30.30. Physics and Science Concepts: Fluid Mechanics, Statics of Fluids Safety: None
PIRA Code(s): 6D20.10 Set up time:none Operation: For best results, observe the sun, moon, or fluorescent lights through the films. Physics and Science Concepts: Optics, Light Spectrum Safety: Keep fingerprints off film.
PIRA Code(s): 6D30.10 Set up time:none Operation: Shine light through the rings so that they are reflected onto a wall. An overhead is good for this. Turn the screws on the frame to change the interference pattern. Physics and Science Concepts: Interference Safety: Over head projector may be obtained from demo 9A36.10.
