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. 

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 #1 Spinner Design

Design New Spinners

Design new spinners!

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.
