Begin the exploration. Discuss with your group: Do like charges repel or attract? Test this with two strips of type-A tape. Can you say anything about whether the force increases, decreases, or stays the same as the distance between the two tapes increases? How is this related to Coulomb's Law? B. Next, rub your finger along the non-sticky side of one of the charged strips of tape (while it is held). Discuss with your group: Does this tape interact differently with a type-A strip of tape after you rubbed it than when before you rubbed it? (Remember that it is OK to "re-charge" your tape at any time.) Is the strip you rubbed still a type-A strip of tape? How do you know? What does rubbing your finger do to the tape? C. When you make a type-A piece of tape, how does that type-A tape get charged? Do you think anything interesting happens to the base tape in this process
