Exactly. Stress will do much harm and no good. Above all else, enjoy yourself while doing your presentation. Maybe you don't have to know everything that you're doing, but if your works are powerful and confident enough to be remembered, you will be remembered more than just a number by the judges w...

Practice, practice, and more practice. Execution is key. You've got one shot, go for it.

That's part of what I feared this year using a sling, and I witnessed the disadvatages of an improperly contructed string last year with my team's trebuchet. I was afraid that either the object would get caught in the sling, it would fall out too early at low launch speeds, or it wouldn't launch as ...

Personally I'd say it's less likely for the rocket to catch an updraft than to have its flight disrupted by the wind, but I have very little experience to speak out of. BTW, where do you guys test the rockets? There's no safe place in NYC to do so, and I'm sure that's why the event doesn't run at Re...

Perhaps (hopefully) the city will be labled on a map, and from there you'll already know what factors affect the city's climate, and matching the climograph to the city will be a breeze

Before I do a poor job of explaining in my own terms, here's a short Wikipedia article on the topic. I'll be doing most of my studying for this event during this week, and Regionals is on Saturday. This is gonna be fun. http://en.wikipedia.org/wiki/Sinuosity The formula is the length of the channel ...

Same 8-) I've been to Regionals once in my lifetime. If you're taking the Meteorology test with a partner, it will really help to know each others' strengths and weaknesses, and how the work is to be sorted out. My partner and I last year wasted too much time disputing over an easy, straighforward q...

I think it's right off the rule sheet. My best is how varying levels of carbon in the atmosphere might be caused, and how that will affect other aspects of climate (e.g global warming, global cooling)

It'd be interesting if we had a set of counterweights to choose from, more launch time and maybe preselected distances.

Yea, you can add weight as long as it doesn't fire without the counterweight. Remember the energy is supposed to come from the counterweight being influenced by gravity. I think it's not allowed because it'd seem as though there is energy stored or something. I'm not sure though. ummm... sorry, but...
