Activity 01
Experiment: Angular Momentum and Turns
Students perform a slow, sustained turn with arms extended, then bring arms close to the body midway through. They record observations about rotation speed change, then the class discusses why it occurred using conservation of angular momentum, connecting the physical law to something they just felt in their own bodies.
Explain the role of center of gravity in maintaining balance during a pirouette.
Facilitation TipDuring Experiment: Angular Momentum and Turns, remind students to count their turns out loud to anchor their perception of speed changes.
What to look forAsk students to stand with feet together and arms extended. Then, have them slowly bring their arms in. Ask: 'What happened to your body's rotation speed, and why?' Record student responses on a whiteboard or digital tool.
