Re: Write It Do It B/C

Other than materials like pipe cleaners and craft supplies, Styrofoam, binder/paper clips and other regular office supplies, straws, beads, lab equipment, and plastic toys like Legos and K'nex, what sorts of other unusual materials (or even usual ones) have you seen at your competitions? At Regiona...

Re: Forensics C

The sugar I remember smoked pretty obviously when I took it out of the flame; salt turned the blue burner flame to orange (anything with sodium will turn it orange, actually). I think our chromatography was just messed up...they didn't give us a beaker right away, so we resorted to a test tube, whi...

Re: Forensics C

That's such a clever abbreviation, lol. Yes, I remember ammonium chloride was the last one, and NaHCO3 was the third one. Did you get your test back? For salt and sucrose, I think I thought that the flame tests didn't ignite, and mixed it up with magnesium sulfate. If it doesn't ignite, does that ju...

Re: Forensics C

Congrats! Also, 4n6... I get it. Ahah, that's clever. Or I'm just slow. :P What were your answers for the powders? I was pretty confident about my answers, but it turned out that I only got NaHCO3 and ammonium chloride correct... I thought that the first powder was cornstarch, since didn't it turn b...

Re: Forensics C

Alpha, yes, I was at Conestoga today. What did you think of the test? Both our A and B teams did pretty badly (I got 12th, bleh); we kind of failed polymers and I mixed up three of the powders... and we ran out of time for the analysis and ended up writing it with wrong information. Ouch. Mass spect...

Re: Forensics C

My partner and I are having trouble with the plastics with a density greater than water. Is the only way to distinguish them by density with the NaCl solutions? If we aren't given these, then how can we tell the differences between PS, PMMA, PC, PETE, and PVC? If I'm not mistaken, I think all of the...

Re: New Jersey 2011

I meant on the actual competition team, not as an alternate, but that's true.

Re: Science Crime Busters B

I don't think there is any way besides burning and microscope identification, but you could try looking at the fiber without a microscope. In general, natural (animal and vegetable) fibers are shorter and more twisted together, with loose ends sticking out like fuzz. Synthetic fibers are smoother, h...

Re: New Jersey 2011

We have quite a few people for the study events, I think. How about lab events?

Re: New Jersey 2011

I'm an eighth grader, like most of our team; we only have three seventh graders and no sixth graders on the team, which will be a problem next year, at least for Grover... And yeah, most (if not all) of the eighth graders work super hard, so South will probably do well next year too.
