Simple Spinners
What is a Gear?
The gears we are using today are SPUR gears and are described by the number of teeth they have.Â
Gears change the:
-Speed
-Torque (power)
-Direction of Force
Whats happening here?
-What is happening with the second gear?
-Are we increasing speed or power in the second gear?
-Is this Gearing UP or Gearing DOWN?
Basic Building Instructions
Each team will build BOTH designs

Challenge #2 Faster Spinner Handle
SPEEEEEEEEEED
Upgrade your spinner handle for speed. Replace all the black gears with white gears.
Challenge #3 Power Time
Motor Time!
New Upgrade! Can you add an electric motor to your spinner handle using just black friction pins?
Hint! Remember that both sides of the motor have a face that spins.
Code Time
Don't forget you will need a little code to activate the motor. Use the example code to give you an idea of how to use the button on the lego hub to get the motor moving.
