BACKGROUND: By investigating the relationship between positive and negative charges the first copy machine was created. In the following activities below we will experiment with how the copy machine and how it relates to electrostatics. DIRECTIONS: Step 1: Rub the glass rod is with the fur or silk. the silk rubs some electrons off the rod. The rod thus becomes negatively charged. Step 2: Placed the negatively charged rod right above the petri dish filled with pepper and salt. At the end of the lesson I should be able to: understand the concept of electric charge.
