I still remember doing this event. The fingerprints was the most confusing part, everything else was easy.

I was wondering if anybody could give me some tips on how to tell if during powder analysis, which powders are mixtures.
Per 3.a. in the rules, you'll be told if they're mixtures or not. The tricky part is figuring out what their components are, and there are too many to practice every combination. I'd make a handful and really work out the process of identifying one component followed by the other. Also, think like a supervisor. It's a far better question to mix sugar with cornstarch than it is to mix sugar and salt, for example.

Fingerprinting is actually the easiest. It's just matching.

I had the burn test at an invitational (MIT Kingwood), and sadly I didn't leave room in my notes for burn tests. :cry: I would recommend that you add information just in case, because you can never be sure what they will put.
Good luck!!

Having notes on burn tests are very useful. Most competitions will have burn tests. I'm sure if you did some research online you could find a flowchart of some sort on this subject.

Most of the competitions that I have been to don't have materials for burn tests but it is definitely something worth having. I use a flowchart for my notes.

Hello

I was wondering about how the hairs will be tested in the Crime Busters State Comp.

Thanks

I have a few questions about what to do for crime busters. It's my first time doing this event.

1.) How are we supposed to identify the mixed solids?
2.) How do we compose the paragraph where we have to write about our research process?
3.) Are we provided with microscopes?

Thank you!
