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): 4C33.50 Set up time:No setup required Operation: Hold one bulb in your hand so that it forces the liquid to enter the other bulb. Physics and Science Concepts: Change of State, Vapor Pressure Safety: Do not grasp too tightly as the glass may break.
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): 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): 5H30.10 Set up time:2 minutes Operation: Plug in the cathode ray tube. Deflect the beam of the CRT by holding a permanent magnet near the edge of the tube. If the beam disappears, you are holding the magnet too close. Also, you can deflect the beam by attaching a battery to the binding posts and adjusting the variable control knob. Physics and Science Concepts: Magnetic Fields and Forces Safety: None
PIRA Code(s): 5K20.10 Set up time:5 minutes Operation: Set up the pole with the right angle clamp and pendulum. Place the permanent magnet so that the copper sheet is in between the two magnet sides. Swing the full copper sheet swing through the magnet. Watch as it damps out quickly. The, flip the pendulum so that the copper comb side is swinging through the magnet. Watch how it swings as if the magnet is not even there. Physics and Science Concepts: Electromagnetic Induction, Eddy Currents Safety: Stand to the side of the pendulum as it swings, not directly in the path.
PIRA Code(s): 5L20.14 Set up time:1 minute Operation: Plug in the circuit. Flip the switch that says line and then put the lever to the automatic side for the whole lamp to light up. Flip the line switch again and move the lever to the middle. Put the line switch on again and move the lever to the manual side. This will heat up the filament. Then move the lever a little away from the manual side for the entire light to be lit. Physics and Science Concepts: AC Circuits Safety: None
