Re: Physical Science Lab
800 mv for both low speed and high speed, or one or the other?

Re: Physical Science Lab
Yeah we were doing really well, but the stupid blade holder during the competition wiggled and screwed us up

Re: Physical Science Lab
We got 8th, and it was because the pole turned so that our windmill was perpendicular to the fan. We did really well on the test, but we would have gotten probably top 3 if the holder had not turned.

Re: Physical Science Lab
At Nationals somehow our blade didn't even turn on low power! But then on high power it got like 2 volts. *sigh*
