Materials Science C

I'm on vacation through the weekend. Not sure if the test is on my laptop (which is with me) or my external hard drive (which isn't). I'll take a look tomorrow.

Anything? It would be amazing if we could get some kind of test up shortly.

Sorry - keep forgetting! I'll upload it when I get home tonight.

Not to be pushy, but it would be really great if you could get it up ASAP. States are tomorrow.

Is it on the test exchange yet? I'm not sure if it's just my computer acting weird.

[andrewwski]

It's there now.

It's there now.

There is a mistake on your answer key. For question 10, you are supposed to list materials in order of increasing Young's modulus. However, the answer key has "rubber" twice instead of having "diamond" in its proper spot.
Everything else looks good though! Thanks for the test, it was very well done, not too easy yet not too hard, and just in time too. My state competition is tomorrow.

Ah yeah, forgot to correct that. We corrected it on the paper copies we used for grading, but I never fixed the document. I'll put up a corrected version at some point.

As a basis of comparison, the average for the test was right around 50. The high score I believe was 82, and the low 21.

Does anyone know who the nats supervisor for this is going to be? I'm just curious.

Also, since most states have happened, did anyone have any labs at states? PA had a test based on stress and strain with testing the deformation of fishing line by adding weights to it.

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).
