Physical Science: Balancing Act (MG)
by Texas Instruments - Simulation Lesson


  • Students will be able to identify a lever and fulcrum.
  • Students will solve one-step equations for balancing different masses on a teeter-totter balance.

  • imbalance
  • mass

About the Lesson

Adapted from a PhET™ simulation, this less involves students using TI-Nspire technology to simulate, observe and manipulate the variables of lever and fulcrum as well as force vectors and torque.


As a result, students will:

  • Describe a lever and fulcrum
  • Determine the positions for different mass arrangements to balance on the teeter-totter.
