Re: Materials Science C
Does anyone know if the event will change at all for next year? I'd really love to see some nanotechnology, nanomaterials stuff like was in some of the trial rules.

Re: Materials Science C
*In our lab at nationals it was quantitative. They gave you a protractor as well as a magnifying glass. After dropping all the drops, what you were supposed to do is magnify them and then use a protractor to estimate. You could get pretty close too because the magnifying glass was pretty decent. Alternatively, to save time, you could magnify the drop, draw it, and then try and figure out the angle, which is what I did.Infinity Flat wrote:It was just comparative IIRC.cjingk96 wrote:In your lab, did you have to quantitatively measure the contact angles or just compare them? If you did have to get quantitative data, how did you do it? I have no idea what I'd do if I got a lab like thatBriscon wrote:WA had a lab on contact angles. We got four different surfaces, and had to compare the contact angle between them, draw the drop etc. We also had to model one of the crystal structures (each team got a different one).

I was referring to the competition at WA state Didn't compete at nationals due to conflict with Astronomy.hpfananu wrote: Actually, it was quantitative.

Oh wow that was stupid of me.

Nationals they had the actual measuring though so it is possible

Re: Materials Science C
Does anyone know if this year they're going to change the focus from last year? If so, what are they going to change it to? For example, last year it was material performance relationship & intermolecular forces and surface chem. Thanks.

Re: Materials Science C
I believe they will change it... I saw a PDF of tenative rules for next year on soinc. I'd check that out, it may have the focus.Wanttoget1st wrote:Does anyone know if this year they're going to change the focus from last year? If so, what are they going to change it to?

Hmm... why can't I find that? Can you link it on here? ThanksCedavis6 wrote:I believe they will change it... I saw a PDF of tenative rules for next year on soinc.

Re: Materials Science C
For people that have done this event last year, how did you go about studying? Right now I have a textbook, but it's college level (1200 pages, need strong math skills to understand), very detailed, and I don't think that all of the material is very relevant. Would you mind telling me how I should go about preparing (mostly for tryouts for a very competitive school)? Thanks!!!
