Re: Replaying Events for 2021

One concern I have that I didn't see discussed already (may have missed it) pertains to the device building policy, which clearly states that builds must be totally constructed by students on the 15-person roster. It seems like it would be feasible for outgoing 9th or 12th graders to complete a buil...

Re: The competition: participant may designate a Timer

Question for anyone that’s judged Mission this year - What’s the best practice for timing? I like the “three timers, middle time counts” method, but this year we have to measure total run time, and timer time. Are people using the lap function on a stopwatch, using multiple stop watches, or having d...

Re: Parachute Payload System

Also based on my interpretation of rule 2b, you have to tape string directly to ping pong. Interesting interpretation. They haven’t used that in an official competition so it hasn’t been an issue yet. Rule 2b doesn’t mention string whatsoever though - just “parachute”. I had been interpreting “tape...

Re: Parachute Payload System

For whatever it’s worth - Our teams have had success making a “basket” for the ball out of a small piece of plastic. We found that not having to tape shroud lines directly to the ball reduced tangles or twisting and deployment was more consistent. Dry cleaning bags and thin cotton string have been ...

Re: Food Science B

Does anyone have any clue on how to determine the pH of a pickle and determine the moisture besides dehydration? Also besides the FDA, does anyone have any other resources that I could use? Indicator paper will show the pH of a pickle if you test some liquid squeezed from it. Moisture can really on...

Re: Experimental Design B/C

Hi all! I don’t know if someone’s asked this question yet because I’m still a bit new to the forums, but I’m a student coach for Experimental Design Div B and a data analyst for our Div C team but I’m kinda having trouble doing/describing the C.E.R. format replacing the Data Analysis section in par...

Re: WHY the metric system exclusively, ESPECIALLY for builds

A Science Olympiad-specific reason (or at least benefit) would be scoring also. With the spreadsheet-aided scoring of building events, having all numbers in decimal form probably simplifies things and reduces errors. I've always felt that growing up in a world with readily accessible pocket calculat...

Re: Food Science B

Does anyone have any thoughts on determining the moisture content of a pickle besides dehydration, then weighing the before and after? I thought about this briefly - maybe density could be used as a proxy for moisture? Pickles in a saltier brine would be less dense by some factor? I'm really not su...

Re: New York 2019

We've been thinking about carpooling already and I doubt it would be that hard to organize if we already have a team interested in this. I'm currently contacting the team in place about getting more funding so we don't ruffle any feathers that we don't have to if it can be avoided. I'll tell you al...
