Re: Science Crime Busters B
I personally missed the burning fiber tests, and plastic tests. Because you got to play with fire, an you got to burn things.
They had it when I was in sixth grade, took it away when I was in seventh grade, then brought it back this year.

Re: Science Crime Busters B
Does anyone know some good links to analyzing burn test results for plastics? Also, what are some density solutions used to determine a plastic's density?

You should check the wiki for more info.EpicFailure wrote:Does anyone know some good links to analyzing burn test results for plastics? Also, what are some density solutions used to determine a plastic's density?

Re: Science Crime Busters B
There's not that much info on plastics on wiki. Also, using the steps in the wiki, it's kind of hard to to differ HDPE from LDPE.

Fifth grade? Is there Scioly in elementary? If so, what division is that...Chemistmax wrote:The last time i did this event was in 5th Grade, (i'm glad there are no more mystery events)
And HDPE is High Density Polyethyne.

Re: Science Crime Busters B
No...frogzorz meant something in the wiki. Well, if you only have to identify one of the two, you can't tell which is the mystery plastic. It was like cornstarch and flour last year. And there is scioly in elementary, it's not very common or official though.Hanelia wrote:Fifth grade? Is there Scioly in elementary?

Re: Science Crime Busters B
Sci. Oly. in Elementary Schools are divisions A1-A3. I think. Not sure about how common it is.
Flour is off white, a little yellow. Cornstarch is totally white. If all else fails (in terms of color-blindness), think of Oobleck.
I'm thinking about memorizing the polymers from here on. Resin Identification Code will now be known as RIC(K). RIC 1 is PETE. RIC 2 is HDPE. RIC 3 is PVC. RIC 4 is LDPE. RIC 5 is PP. RIC 6 is PS. w00t.

Re: Science Crime Busters B
Hey guys, kinda need some help here for hairs...>.<
Somehow, when I put the hairs under the microscope, they look NOTHING like what they're supposed to look like on the diagrams...
Anyone have any advice on dog/cat/human hair and what to do about it? Maybe I'm using a bad reference sheet...so a website with accurate diagrams would be good as well. Grr.
Thanks guys
