An unmoving electric charge (AKA static electricity) can be pretty easily produced by, for example, rubbing fabric against a balloon (they gave us various types of fabric, paper, foil, etc, and a balloon. I was amazed by how many teams we saw rubbing the balloon against their
hair. I'm thinking,
why would you do that when you already have these other materials to rub against the balloon?),

I agree about the rubbing on the hair... except that I know for a fact the gold medal team was one of the teams that did that.
Urgh.

Okay, I'm not saying it doesn't work, I'm just saying why would you do that to your hair when you don't have to? lol.

You guys probably did something wrong, like forget to put your team name at the top of the page or something like that, and so you didnt get the points for those sections. Is that possible?

Do you know if the people on your team had time to do everything? If they didn't have time to do a couple parts that could really hurt them.

they did say they didn't get to the last part but I didn't think that would kill us that bad...

Look at the rubric on the second link on here:
http://soinc.org/exper_design_b
In Experimental Design there's no real last section. The "last" section completed would probably depend on how your team decided to split up each of the parts. If your team didn't have time to make the graph or do the statistical analysis, you would lose a large amount of points, possibly even more than on that rubric (I don't remember how many points were on each section at states).
