Key Features
Rotating disc or arm drives an indicator pointer.
Pointer repeats a fixed cycle that can be related to time intervals.
Introduces periodic motion and synchronisation.
Worked by hand; no electricity needed.

Operation
Manual mechanical motion
How It Is Used
Place the model on a stable surface, set the mechanism moving and watch the pointer travel through its cycle. Students relate each cycle to a time interval and compare slow and fast cycles. Handle the moving parts carefully.
