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.

http://phet.colorado.edu/en/simulation/balloons
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:)
After the balloon is charged it sticks to the sweater, and when the pucks are both positively charged they repel but when oppositly charged they attract. And a description of static electricity is when we slide down a slide then touch one of those metal things then it shocks you.
ReplyDeleteI didn't know sliding down a slide would cause static electricity! cool.
DeleteThe balloon sticks to the sweater afterwards because they have opposite charges therefore attract towards each other. When you bring the charged balloon towards the sweater the charges on the wall come together. For the puck you mus make sure the charges or opposite so that you can score because if they are the same they repel.
ReplyDeleteAt first i was just putting random charges, before realizing that I already knew opposites attract and like charges repel.
DeleteAt first i didn't know what to do in the hockey game but then i understood it. It was so annoying and time consuming.
Deletelol @Joceline :D it was annoying??? haha
DeleteThe hockey game was confusing at first but i remembered what we talked about in class and how opposites attract. AFter a while i scored the puck lol
The balloon sticks to the sweater once the charges are opposite because opposites attract. When playing the hockey game with a difficulty level of one and put a positive charge behind the original charge and a negative charge on the other side of the barrier the goal is made. A description of static electricity would be when your sock stick to things when they get out the dryer.
ReplyDeleteSame Thing For Me
DeleteThe balloon sticks to the sweater because the charges are no the same on e is positive and the other is negative. In the hockey game you have to make sure that the charges are opposite and that they align in order to score a goal. i spent a lot of time in this game. It was annoying. If i were a goalie I would need a positive charge in order to repel the puck.
ReplyDeleteI agree it did take longer and being a goalie is hard core :)
Deletethe reason why the balloon sticks to the sweater is bc. the balloon has a positve charge while the sweater had a negative charge. In order to score in the hockey game, the charges have to be opposite from each other and align with the one behind the barrier. One description of static electricity would be rubbing your feet across the carpet and then touching a metal object.
ReplyDeleteDoes that really happen? I've never heard of it before. Have you tried it before? If so what happen and how it felt?
DeleteThe balloon stuck to the sweated due to the fact that the balloon was positive and the sweater had a negative charge. Opposites attract right?... While in the hockey game which did like Joceline mentioned take up a little more time you had to align opposite charges. A good example of electrostatics is rubbing a balloon to your stomach. It usually attracts to stuff after that. I also have a question. Why is it that when you turn of your TV your hair flies in the direction of the object??

ReplyDeleteThe Balloon sticks to the sweater because they have opposite charges so they attract. the charges on the wall come together. the hockey game you have to make sure their are apposite charges if not the puck will repel. and an example of static electricity is when some one rubs the hand across the hand rail quick and touches someone to shock them
ReplyDeleteI didnt get to play the hockey game, but the way you described it made me want to.
DeleteWhy are you trying to give us viruses!? lol. Well I did the balloon simulation. After the balloon is charged it it is filled with electrons making it negatively charged. The sweater stays with the protons making it positively charged. The balloon sticks to the sweater because negative charges and positive charges attract. When the balloon gets close to the wall the negative charges in the wall repel, and the positive charges attract.
ReplyDeleteSomething that happens in every day life involving charges is when you brush your hair. Brushing your hair charges your hair so when you put your hand by close by your hair attracts to it.
DeleteThe sweater and the ballon attract because the have different charges causing them to attract. And the charges in the wall will repeal and some will attract because the wall has negative and positive charges.
