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
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): 8A10.10 Set up time:none Operation: Plug in the model. Flip the right switch to have the planets move and the left switch to turn the light bulb on which represents the earth. Physics and Science Concepts: Planetary Astronomy, Solar System Safety: Do not touch the light bulb, it may get hot.
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.
