### Science

Upper Elementary - Levers
Title: Can You Lift 100 kilograms?
The goal of this lesson is to enable students to investigate the design and operation of levers by changing the position from which effort is exerted and the amount of effort.

Upper Elementary - Pendulums
Title: The Secret of Trapezes.
In this set of lessons, the students investigate three factors: the weight of the clay on the trapeze; the angle of release; and the length of the wire.
