1. You rub balloons in your hair and then hang them like in the picture below. Explain why you think they move apart and what might affect how far apart they get.
2. Test your ideas using Electric Field Hockey in the Practice mode. Make a table to record your observations about what affects the direction and speed of the puck. Your table should demonstrate that you have run controlled tests with all the variables.
3. Reflect on your ideas from question #1 and your data from question #2. How do your observations support, dispute or add to your ideas about what affects how charged bodies interact?
4. As you put charges onto the playing area, arrows appear on the puck.
· What do you think the arrows on the puck are illustrating?
· How do the arrows from the positive charges compare and contrast to the ones from the negative balls?
· Investigate how you can use the arrows to predict the motion of the puck.
5. Write an explanation of how you can predict the motion of a charged hockey puck that is moved by other charged pucks. Explain using examples and drawings that include:
· How to use free body diagrams and vector addition.
· How negative and positive charges compare and contrast.
