This week we are discussing electrostatics in class and we are doing an electrostatics lab as well. Go to the following websites and play with the simulations.

For the balloon simulation answer the following questions:
Why does the balloon stick to the sweater after it is charged? What happens to the charges in the wall when you bring the charged balloon near it?
For the hockey simulation answer the following questions:
Leave the charge on the puck as positive. What do you have to do on difficulty level 1 in order to score a goal? (how many charges did you use?, were the charges positive or negative?) If you were a goalie on this hockey team and the puck had a positive charge what charge would you want to have in order to keep the puck from going into the goal?
If you are brave you can attempt difficulty level 2 and let me know if you were able to score a goal.
For your post this week answer the questions over the simulations and also describe something that you see happening everyday that involves static electricity. Remember that to receive full credit for your blog you must post an original comment and comment on someone else's post. Your post is due by 10pm on May 5. As always keep it clean and have fun:)
