Which is heavier?

Illustrative MathematicsVaries

The purpose of this task is for students to use a balance scale to compare the weights of two different objects. It is best if the objects appear to be close to the same weight so that comparing them on a balance scale is meaningful. This task also introduces students to the way in which a balance scale works, which is not obvious. The students should become familiar with the word 'heavy' and its reference to weight.
