What Can We Lose? What Do We Lose as we Gain Force With A Lever?

Third graders view a demonstration of a teeter totter as a basis for assessing pre-knowledge of a lever. They create a KwL chart. Students work in small groups to conduct a variety of experiments.

They write a summary statement about the force required to lift a load and the distance the load travels.
