|1||A New Kind of Motion
Introduction to rotation as a second kind of motion, distinct from translational motion, as a classroom discussion.
A classroom discussion to develop an understanding of the parameters that determine torque.
||Screwdriver Springboard -
A classroom discussion to determine the advantages of different-sized screwdrivers.

|LABS - The unlinked titles below are available in the Conceptual Physics lab manual from Pearson Education - Amazon link|
Personal experience in balancing an increasing torque created with a single force.
Personal experience in waving the mysterious rotational batons. Equal mass, equal length, but not equal somehow.
|3||A Question of Balance
Mixed activity: PhET sim and actual materials to investigate balancing torques.
|4||Sit on It and Rotate
Personal experiences in conservation angular momentum. Perennial student favorite.
|Kinetic Karnival: Rotation - Answers
Jearl Walker's spin (!) on rotational mechanics.
|YouTube Physics: The
Ultimate Backyard Water Slide
A thrill ride in his own back yard. Down the ramp, up the jump, and into the pool. Almost.
