PIRA Code(s): 1M20.10 Set up time:none Operation: These may be used by themselves or with other demonstrations. Physics and Science Concepts: Mechanics, Mechanical Advantage, Simple Machines Safety: None
PIRA Code(s): 1M20.30 Set up time:5 minutes Operation: Set the empty friction box on the incline with weights attached to the string on the other side of the pulley so that the box slides forward. Then, gradually increase the angle of the plane until the box and the weights reach equilibrium. Physics and Science Concepts: Equilibrium of forces, Mechanics, Work and Energy Safety: None
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): 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
