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): 1Q40.30, 1Q50.24 Set up time:3 minutes Operation: Stand on the stool as it remains still. Have someone start the motor and place the bicycle wheel next to it to get it to start spinning. Take the spinning wheel in your hands and turn the wheel in a horizontal position and you should spin. When the wheel is placed vertical again, you will spin the opposite direction.
Use the motor to start the wheel spinning. Hold on to the cord attached to the axle and the wheel will remain vertical. Physics and Science Concepts: Mechanics, Rotational Dynamics Safety: Do not get items caught in the motor or the spokes of the tire. Hold wheel out from the body as far as possible
PIRA Code(s): 1Q50.30 Set up time:1 minute Operation: Rotational Dynamics, Mechanics, Gyroscopic Motion Physics and Science Concepts: Rotational Dynamics, Mechanics, Gyroscopic Motion Safety: The central gyroscope is quite heavy and can pinch fingers.
PIRA Code(s): 1Q50.60 Set up time:2 minutes Operation: Use the string or turn the rotor with your thumb to start the gyroscope spinning. Take care to hold the gyroscope and metal hold in place relative to the top block of wood. Then, spin the wooden block, stop it, and reverse the direction of the spin. The gyroscope will do a spin flip. Physics and Science Concepts: Rotational dynamics, Mechanics Safety: None
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
