PhET Balancing Act Activity Guide
The PhET: Balancing Act Activity Guide is used along with the free Next Generation Simulation "PhET: Balancing Act". Students learn the relationship between balance, torque, and rotational equilibrium as they use proportional reasoning to balance objects on a lever arm (teeter totter). The best part is that students don’t even know they are learning, they just think they are having fun!

The Balancing Act Activity Guide will lead students through the simulation to experiment with balancing objects of different masses and to predict how changing the positions of the masses will effect the motion of the plank. Students will then write their own mathematical rule for predicting the placement of masses and will practice using their rule to identify the mass of mystery objects. Finally, “the Game” will assess students at 4 levels of difficulty giving them the opportunity start over with a new set of problems.

This product includes the Balancing Act Activity Guide and Answer Key in PDF format as well as a Getting Started Guide for teachers.
