Re: Detector Building C

The top-down photograph requires "labels identifying all components and detailing their functions". For anyone who has done this event (or an ES) does that mean I need to label every resistor, every wire, and all of the pins on the Arduino I am using?

Re: Science Olympiad Events 2019-2020

Fermi leaving decreases my hype for next year by 90%. Nothing can remotely be compared to that event in terms of fun.

Re: End Task

Curious about what you guys think regarding the phrasing of "movement stops". In my last competition, the ES had no problems with us calling time and flicking our switch after our motor stalled the platform at its final position. Our motor was still wiggling a bit, but the platform had stopped. Is t...

Re: Screw Task

How do you guys plan on doing this task? I was planning on doing like what was suggested by "rolling" the screw. But I feel like that really isn't using gravity directly. Any ideas on how to do this using gravity? We are thinking of tying a weight to a string and wrapping the string around the scre...

Re: Endothermic Task

Our team is currently thinking of using a Peltier cooler and detecting the change in the heat with a thermistor. However, I can't figure out whether this would be endothermic. The cooler definitely loses heat so by definition, the thermistor touching it would be gaining heat (so endothermic). Would...

Re: Fermi Questions C

Heres another quizlet set that I made: https://quizlet.com/286400676/fermi-facts-flash-cards/

It's essentially a copy of the Wikipedia "orders of magnitude" pages for stuff like mass, length, energy etc. Those pages are really useful.

Re: Endothermic Task

I'm trying to find a good PTC thermistor, but everything I've seen has an ideal operating temperature of around 25 degrees Celsius. Anyone have a thermistor with a lower ideal temperature? (or a site that lets you sort by curie point).

Re: Allowed use of Mouse trap?

Given that we are allowed to use mousetraps and that certain mousetraps can go off somewhat easily from vibrations, is there a way to alter a mousetrap to make it less likely to snap on accident? Or are there specific brands/types of mousetraps that would be more consistent? I am just a bit curious...

Re: Balloon Task

I'm probably overlooking a really obvious solution, but how do you plan on initiating the reaction? If you have a hole in a beaker to drop baking soda in (for example), wouldn't the CO2 just escape from that hole rather than inflate the balloon? Do you just make your hole as small as possible?
