How can a teeter-totter balance when the two people are different sizes? Show classes how this works through a simulation. Scholars play with a teeter-totter to show how different masses and their placement affect balance. Once they have mastered the simulation, they play a game to test their knowledge.

Instructional Ideas

• Model the introduction and balance lab; once groups understand, allow them to work in pairs on the game

Classroom Considerations

• When teachers register for free, they gain access to teacher tips, lesson plans, and other related resources
• Depending upon how you use the resource, you might need a computer for every two pupils in class

Pros

• Simulation works in a number of different languages
• Game is fun and engaging for students

Cons

• None
