PIRA Code(s): 1M40.10 Set up time:5 minutes Operation: Hook the bowling ball onto the chain. Pull the bowling ball back until it reaches your nose. Release the ball and do not move. Let the ball come back and show how it will not reach your nose again. *For use in lecture room 131. Physics and Science Concepts: Mechanics, Work and Energy Safety: Do not give the ball an initial velocity or move forward once the ball is release. Warning: it’s hard not to flinch.
PIRA Code(s): 1M40.20 Set up time:none Operation: Place ball at the top of track and let it fall. To show students the minimum height required to loop the loop, place the ball on the track at a height that is about double the height of the loop. Physics and Science Concepts: Mechanics, Work and Energy, Conservation of Energy, Centripetal Force Safety: Do not stand where the ball exits the track.
PIRA Code(s): 5F20.50 Set up time:5 minutes Operation: First, attach the metal rods to the battery by unscrewing the black caps and place the rods around the screws. Then replace the caps. Next, clip one light bulb on the metal rods to show a circuit with a single light bulb. To show series circuits, clip two bulbs together and place the end of each clip on opposite rods. To show parallel circuits, clip each bulb separately to the rods. The bulbs in series will glow less brightly than the bulbs in parallel. Physics and Science Concepts: Parallel and series circuits Safety: The ends of the rods pose an eye hazard.
PIRA Code(s): 5G50.50 Set up time:2 minutes Operation: A superconductor disc is placed in a styrofoam dish and liquid nitrogen is added to the dish. A small magnet is placed on top and within a few seconds it begins to levitate. Physics and Science Concepts: Superconductivity, Magnetic Materials Safety: Liquid Nitrogen can be obtained from the machine shop.
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
