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): 4A30.10 Set up time:1 minute Operation: Use a Bunsen burner to heat a bimetal strip and it will bend Physics and Science Concepts: Thermodynamics, Thermal Properties of Matter, Thermal Expansion Safety: Use caution when dealing with the Bunsen burner. Bunsen burner not included.
PIRA Code(s): 4E30.10 Set up time:5 minutes Operation: Fill sphere with water and submerge in buckets of water or liquid nitrogen at different temperatures. Dewar of liquid nitrogen and bucket can be obtained in the physics machine shop. Physics and Science Concepts: Gas Laws, Thermodynamics Safety: Always wear protective clothing when handling liquid nitrogen.
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.
