Electrostatics-Week of 4/29-5/5

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:)

blog for 4/15-4/21: due 4/21 by 10 pm

Since we have one week until your science TAKS test your blog this week will again be reviewing for it.  Using the same links from last week pick a different game to play and let me know how it goes.  Post questions if you have any so I can help you.
As always your blog is due Sunday night by 10pm.  Remember to get full credit you must post an original comment and comment on someone elses post.  Keep it clean and have fun.  Happy blogging:)

week of 4/7-4/14-blog post due on 4/14

In two weeks you will be taking the science TAKS test.  I would like for you to spend some time everyday reviewing.  There are many online resources to use when you review as well as reviewing your graded work from class and your TAKS review booklet.  Here are some links to online review games and resources.

Remember you must post your own original comment and comment on someone else's post.  As always keep it clean and have fun.  Your post is due by 10pm on Sunday, April 14.
