Re: Michigan 2010-2011

Wow, there really are not too many from Michigan on here, that’s odd considering we have the second most teams only behind New York. I'm going to make as safe bet for the results at State going to be very similar to last year with Gran Haven winning and West Ottawa/Troy or another region 12 team tha...

Re: Mousetrap Vehicle C

This may be a stupid question, but how are you guys attaching your lever arm to your mousetraps? last year we had a really inelegant and weighty hotglue-string solution, and we can't seem to find dowels that can bridge the two lever arms to superglue without weighing the car down... Me? I soldered ...

Re: Mousetrap Vehicle C

First off, this year, class 2 is even less useful, since you only have 3 m to "charge" the spring, but it still needs to go 7. I suppose a composite system could work? That’s my point use the short track to "charge" a spring that is only used to get vehicle going on the way back and then continue l...

Re: Mousetrap Vehicle C

The idea is to make it easier for the judges to see that no "push" is given to the vehicle. A push would use energy that didn't come from the mousetrap to propel the vehicle. That's good to know other people noticed that there were teams that gave their vehicle a little boost to start their vehicle...

Re: Mousetrap Vehicle C

It's a 16oz plastic cup, placed upside down at the start line. Your vehicle is supposed to push it to the 3m line, then reverse direction and come to rest at the -4m line. If the cup is tipped over, measurements are based on where the cup comes to rest. So if I understand this correctly they will u...

Re: Mousetrap Vehicle C

I guessing that all parts of the vehicle must fit in the 1m square that opens up a lot compared to last year, our vehicle had good tracking [no less than an inch variation from start to finish] so with the ability to have such wide wheel base makes tracking much easier than it was in other events. O...

Re: Mousetrap Vehicle C

I thought about this for a long time and don’t know what category my vehicle fit into. I had my vehicle coast the final 2-3 meters on the way back. The each team has in the event is the lever arm will only pull x length of string from axel, so I found ways to get the string used to get the vehicle t...

Re: Mousetrap Vehicle C

Now that I'm done as a competitor in Science Olympiad I would like to pass of the stuff that I have left for this event. The winning team used a compound lever design which allowed for a shorter length arm to pull off an equal amount of string from an axel that provides the movement for the vehicle ...

Re: Bottle Rocket B

In the last few weeks of high school my school's physics class made bottle rockets, and because I had been my own science Olympiad class I decided to make one too. The model I made was crazy simple and was literally like a missile went straight up and strait down with a lot force (bounced a good 7 f...
