Re: Experimental Design B/C

What did you all do for your experiment? Yes, I am very interested in how other teams approached this prompt :? Well, we used time for our first IV and measured force on the dynamometer at different time intervals. We were about to stick with one variable but I suggested we just do the experiment w...

Re: Experimental Design B/C

I had my state competition last weekend and the experiment had an interesting twist so I thought I'd mention it here. The materials we were given included a dynamometer (measures grip force), three different types of gloves, a stopwatch (even though we can bring in one), an angle measuring device (a...

Re: Technical Problem Solving C

Hey guys,

I had a question about the Captain's Tryouts test from Webster Schroeder High School. For anyone who has taken it, what did you guys get for the area of the foot prints in Station 3? I think we got ~75 square centimeters.... just wondering how close we were. :D

Re: Rules

I had a question about the competition rules for Wright Stuff. Under section (f), we can use any type of winder, "but electricity may not be available." I recently saw a torque meter that utilizes a digital pocket scale. Would this be allowed? I can't tell if the rules are hinting at proctors not be...

Re: Texas 2015

Anyone have the Lone Star Regional Results? Which Lone Star Regional? There's the one at Lone Star - CyFair and also the one at Lone Star - University Park, but I'm guessing you're asking about the latter since that was the most recent one. I didn't compete myself, was only there during the awards ...

Re: Texas 2015

Something that's bothering me right now is the inequity in conflicts. I don't mind too much when all teams have the same conflicts cause it's something everyone has to work around. But due to the use of both odd/even blocking and team number blocking, this schedule creates six different sets of conf...

Just to add to the discussion about updated FAQs, I found the following one recently:
