The best place to start is to look at the Crime Busters Wiki. For hair analysis, look at them under a microscope and do some googling to figure out how you're going to tell them apart. For fibers, do some burn tests and try to figure out the difference between the way animal, vegetable, and synthetic fibers burn. North Carolina has a really nice page with good videos for Crime Busters, including how to do a fiber test: http://www.sciencenc.com/event-help/crimebusters.php
A lot of Crime Busters you're going to have to figure out on your own because what works for one person doesn't necessarily work for the next person. Keep practicing, and you'll get it.

Good luck and have fun!

Do we need to have blood on our resource sheet

[Olympian_Cau2134]

Does anybody know what form the polymers at the event will be in (like flakes or a cube)?

Does anyone know what we need to have on our resource page? Just the general information.

@aljones, I don't think so. We've never had blood, and it's not mentioned in the parameters.

I wouldn't focus on it too much, as the most you'll usually get is the origin of the impact, which isn't something notes will really help with. That being said, I once got some questions about it on an Invitational test a few years ago and ever since then I've had a text box on my notes for it. Basically if you have the time and space, go ahead, but you don't really HAVE to have it.

Technically there is nothing in the rules about this, so a proctor can give you pretty much anything, but if you have a decent proctor you will probably get some pellets (not really flakes, but I guess they could be cubes). That's what they use at State and Nationals (then again, I could be wrong about Nationals, I honestly don't remember the test that well).

Does anyone know what we need to have on our resource page? Just the general information.

Read the rules, look at the Crime Busters Wiki. I would recommend having the properties of all the substances and a fingerprint chart, especially if you're inexperienced, and basic information about anything listed in the rules.

I don't think there's really one specific site with everything, but the Crime Busters page on soinc.org has A TON of information and resources that should help. Beyond that, google.
