Lesson 6.9 Review: Pan-Balance Problems
Balance Beam Activity. Use basic equation principles with this virtual balance to find the weights of various figures. You are presented with a number of shapes and one of their weights is known. Your goal is to find the weights of the other objects by finding the relationships between the objects of various weights. This is achieved with a simulation of a balance beam to tell you how the weights relate.
