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
