Thinking about Static Electricity 1. Sarah rubs a balloon on her hair. She touches the balloon to the wall and lets go. She sees that the balloon stays on the wall. If Sarah could see what is happening between the balloon and the wall, what would it look like? a. Draw a picture to show what you think is happening between the balloon and the wall right before the balloon sticks to the wall. Use pictures or symbols to show the interaction between the balloon and the wall. b. Explain what your picture shows. Include how your drawing shows the interaction between the balloon and the wall. Students in Mr. Miller's class watched a demonstration on electric charge. In the first example of an interaction, Mr. Miller brought two plastic rings together. The rings moved apart when they got near each other like in Figure A. In the second example of the interaction, the rings moved toward each other like in Figure B. Mr. Miller asked the students if the two Q O OO examples of interactions provided convincing evidence Figure A Figure B that both rings in each example were electrically charged. Here is what some students said: Faith: I think both examples provide evidence that all of the rings in both interactions were electrically charged. Milo: I think only the first example provides evidence that both rings in an interaction were electrically charged. Judd: I think only the second example provides evidence that both rings in an interaction were electrically charged. Fran: I think neither example provides evidence that both rings in an interaction were electrically charged. Write who you agree with the most and explain your reasoning
