It really just depends on the test. I've had some tests in which the analysis is already written for you and you just need to right in the info on what unknowns point to a suspect. I've also had tests in which they just give us a blank sheet of paper with lines on it and have us write an analysis (in complete sentences). It really just depends on the test. Sorry, I wish I could be more helpful.

So a couple of my friends in B division have a question. Can anyone differentiate between inconclusive and circumstantial evidence?

Circumstantial evidence is a piece of evidence that points a finger towards someone or a group of people, but does not prove anyone's guilt, while inconclusive evidence is evidence that does not even incriminate anyone. For example, a janitor's fingerprint on a door handle of a school after hours is inconclusive, since the janitor had every right to be in the school after-hours. Meanwhile, if a student's fingerprint was found there after-hours, it would by circumstantial. On a completely different note, does anyone have a definite way to distinguish how many and which powders are in a mixture of two or three?

Honestly, I think it truly depends on the person. I have found that if you just slow down and really look at both the powder sample and the reactions, you can kind of tell what parts are reacting and such. The only thing I can say with this event is practice, practice, practice. Close to nats, I focused on taking powders tests comprised solely of mixtures and I think it was beneficial. Turned out pretty well I guess (got 4th at nats).

Hello Everyone,

This is my first time coaching a Science Olympiad team. Can anyone share the last test (2014) or links to some good resources for this subject?

Appreciate any help,
Thanks in advance.

If you're referring to the 2014 National test, no one has it yet, but it will be available for purchase sometime in the fall I believe, usually at about the same time as the rules. If you're looking for some good resources, I would recommend starting with the Crime Busters Wiki and the Crime Busters page on soinc.org, which is actually one of the most helpful event pages from soinc (at least in my opinion). If you get the supplies for your team and provide a few helpful pushes along the way, they should do great.

Thanks for agreeing to coach someone! :)
