Re: Forensics C

What all do we need to know for this event?
The rules manual is a good place to start, as is the scioly.org page for forensics: https://scioly.org/wiki/index.php/Forensics

Re: Forensics C

I'm not going to nats but I was just curious, how do you guys practice for forensics over the summer? If you are willing to spend the money you can buy a lot of the materials online through Science Olympiad or other companies. You can surprisingly even get cheap equipment and make it work (I have a...

Re: String Problems

I have used fishing line before for the drive string, especially because it is so thin and can permit more loops around the axle than other times of string, however, I found that after a few runs, it began to curl up/retain the curled up shape (instead of remaining straight). That made it a nuisanc...

Re: Forensics C

I usually only use the appearance as a last resort to narrowing down. Lets say there are 2 with a yellow flame test, and they have the same solubility, etc. then I would go to the appearance... I think they were referring to tests where there are no flame tests... Some of the powders I have worked ...

Re: Forensics C

The Solon Invitational forensics was absolutely insane. My partner's first time doing it, so I had her literally just read and make lists of the suspects/what would implicate them. That alone took her 10 minutes (but she did find a bonus at the end of the instructions). We were lost at what to do w...

Re: String Problems

We've been using etiher monofilament or fluorocarbon fishing line (don't recall) which you can probably obtain relatively easily (Walmart, pigeon's Sporting Goods, Target, Amazon, etc.) I think the most annoying part about using it is the fact that it's slippery and won't hold knots. We just used bl...

Re: Forensics C

Does anyone have some advice on how to identify a given plastic sample? (no burn tests permitted, no solutions of different densities or indices provided) Guessing you went to the Solon Invitational?
