To explore (how somet ang happens, it's often useful to think about when it doesn't happen, or when you think it might not happen. For the flowing experiments, you will rub the given pair of objects together, and determine if they have become charged. a) For each pair below, record your predictions (in your notebook and on the whiteboard) about whether or not the following objects will be come charged. a.
