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.

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 that

It was just comparative IIRC.

*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.

I was referring to the competition at WA state Didn't compete at nationals due to conflict with Astronomy.

Oh wow that was stupid of me. Sorry about that.
Nationals they had the actual measuring though so it is possible

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.

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.

Hmm... why can't I find that? Can you link it on here? Thanks

IDK where I saw it, I'll try and find it.

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!!!
