At a tournament, if I am given hair samples in a bag, not in a microscope slide, how should I go about trying to figure out what it is?
The rules allow competitors to bring microscope slides and cover slips, which mostly indicates that the competitors technically should be making their own slides at competition with the hairs provided (unless given microscope images which is 1000x less fun than actually trying to ID itAMAZHANG wrote:At a tournament, if I am given hair samples in a bag, not in a microscope slide, how should I go about trying to figure out what it is?
Ohhh, I see. I was leaning towards that option but since I have to do the analysis, polymers, etc.. I was wondering if there was a quicker way. I guess not lol, thanks so much!pikachu4919 wrote:The rules allow competitors to bring microscope slides and cover slips, which mostly indicates that the competitors technically should be making their own slides at competition with the hairs provided (unless given microscope images which is 1000x less fun than actually trying to ID itAMAZHANG wrote:At a tournament, if I am given hair samples in a bag, not in a microscope slide, how should I go about trying to figure out what it is?)
I remember when I competed, by the time I was reaching my third/fourth year competing in forensics, I just accepted that most microscopes are not going to be top-notch and started relying on gut intuition to guess the hairs based on what I knew about the characteristics of the animalAMAZHANG wrote:Ohhh, I see.

The ones in the Ward's Science kits are 2" x 2" cubes tho, not the tiny pellets that you usually see.AMAZHANG wrote:alylam wrote:This is a little off topic from the discussion above, but does anyone know where invites get the samples they use in the plastics/polymers section?

I know Ward's Science sells kits specifically for Science Olympiad. Here's the link for Forensics: https://wardsci.com/store/catalog/produ ... 470231-372 It says it includes the polymers in the description. Hope that helps!
Haha I agree about the price, oh I wasn't sure if it was cubes or whatnot. I know my junior high always had the pellets that you would see in competition but I don't know where they're from rippikachu4919 wrote:The ones in the Ward's Science kits are 2" x 2" cubes tho, not the tiny pellets that you usually see.AMAZHANG wrote:alylam wrote:This is a little off topic from the discussion above, but does anyone know where invites get the samples they use in the plastics/polymers section?

Lol Ward's products are kinda overpriced and overrated imo...
