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): 3B20.11 Set up time:2 minutes Operation: Lay the slinky down on the ground and push it back and forth lengthwise to make longitudinal waves. Physics and Science Concepts: Longitudinal Waves Safety: Ends of slinky may be sharp or may tangle.
PIRA Code(s): 1Q30.60 Set up time:10 minutes Operation: Spin the frame and watch the two balls move outwards. For the plexiglass demo, squirt green liquid (or pour) into the frame so that the liquid is at least an inch deep. Then, plug in the cord. Physics and Science Concepts: Centrifugal force Safety: Make sure objects and people are well clear of the spinning frame. Wear safety goggles during operation.
