Today I was introducing rotational motion and balancing Torques so naturally the conversation moved towards seesaws. I constructed some examples using Interactive Physics but what really got everyone excited was the balancing game on PhET. The fact that the it is called a game and it was against the clock made a huge difference to the level of engagement. Interesting because when I played the game at home I thought it rather boring, funny how even a simple game can become interesting when you play it with your mates.
