Description

Play with objects on a teeter totter to learn about balance. Test what you've learned by trying the Balance Challenge game.

Sample Learning Goals

  • Predict how objects of various masses can be used to make a plank balance.
  • Predict how changing the positions of the masses on the plank will affect the motion of the plank.
  • Write rules to predict which way a plank will tilt when objects are placed on it.
  • Use your rules to solve puzzles about balancing.

Standards Alignment

Common Core - Math

6.RP.A.3
Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
