Definitely the best tests I've had since starting SciOly. Sound proctor was super nice and analyzed our data for us immediately, and Sounds test was pretty easy, though we didn't finish because we didn't prioritize questions right (oops), Circuits test was a huge wake-up call that we had been studying the wrong things (big oops), but I feel the lab portion had too little time for each activity (but then again we had done very little practice on this), and Disease was one of the few tests I've seen that had less than 10 points dedicated to random disease trivia (I think, don't remember exactly), yet was challenging because of both material covered and length.

10/10 would go again, also Berkeley was amazing since we accidentally stumbled into some mini-forest/garden near homerooms which was really pretty. (unfortunately we didn't have time to see the Botanical Gardens :( )
I agree about circuit, we placed 6th and we didn't do well on the lab portion, we knew how to do it but having three minutes to make all measurements and set up the breadboard wasn't enough for us.

Mouse Trap Vehicle ran regional rules which was somewhat surprising, given the fact they had run National Rules the previous two years.

Is there a video recording of the awards ceremony?

Anyone know if they returned Wright stuff score sheets to any teams, because both our schools teams got everything but Wright?

Final results can be found here. Scores are considered final, so teams may not file an appeal/challenge scores. Tests/key distribution will occur within the next week (stay tuned for a future email!) Wright Stuff rubrics will be emailed out with the tests/keys. Photos will be posted within the next two weeks.

Does anyone know if Mira Loma was stacked?

The best I can tell is NO. Looking at their composite score, best of RED and BLUE teams in each event, they scored 253. At their own invitational a few weeks ago their composite score was 120. That tells me they did not send all of their best students/devices. Someone said there were other events in the Bay Area like Science Bowl and an important debate event that could have affected Mira Loma's participation.

Post Competition Blurb

Hello everyone! I'm the Protein Modeling event supervisor. It was a great experience; really glad to have come out. The GGSO directors board was crazy organized with everything and super nice as well. Protein can be a lot to run, but they made it manageable and breezy (or as breezy as it can be). I talked to a few of you competitors after the competition, and y'all were also very sweet. It's clear you're really invested and want to learn stuff, which warms my heart tremendously.

Anyway, some general comments. I can't divulge much about raw scores, and I most certainly can't divulge anything about MSOE-released materials.

Stats
Here's an unlabeled-axes-graph of overall scores. I know there's a bit of mystique about onsites, so here's an unlabeled-axes-graph of onsite build scores.

The average on the written exam was ~45%, and there was a good spread from ~15% to ~75%. I generally aim for averages of 50%, and for the highest score to be in the 70-80% range. I'm fairly satisfied with my spread. I just wish I had less ties, but the chances of teams getting the same overall score on all three sections is next to none so I didn't have to use any tiebreakers.

Comments about Performance
As you all know, the scoring rubric was recently changed from 40/30/30 to 20/40/40. This happened 3 days before GGSO, so the exams had already been printed and retained the original breakdown. The onsite rubric was out of 30, but it had to be normalized to 40 for the new system.

I did not grade the onsite section (I trained a volunteer to do it for all the entirety of the day), so I can't comment too specifically about this. Looking at all of them at the end of the day, and generally watching over the kids during the testing periods, my first impression was that at least a few teams had some kind of time crunch with these. There was one onsite that was basically a swirl with endcaps, and I noted that some teams waited until the last 10 or so minutes to go get their endcaps. However, most teams did get the general shape down. Onsite scores were fairly close together.

As for the written exam, I was generally satisfied with performance. Most teams were able to at least make an attempt at every question. I don't think anyone got a perfect score on the MC, but one or two teams came very very close. A good handful broke 10/15. The exam was originally harder, having more advanced protein topics (cold denaturation, thermo). While writing the test, I was debating between an exam which had a deeper testing of concepts and did not conform to MSOE's format, and one that was in the MSOE format. The former is better at gauging understanding and less prone to ties since it isn't constrained to 30 points, but it also take practice to ace the MSOE format. I ended up settling for something that was MSOE format, but had a few more MC questions than MSOE would normally give. The exam was made easier after the MIT Invite. I was one of the people involved in organizing Protein Modeling, and the distribution of scores and overall performance gave me a sense of how much high schoolers would realistically know.

The prebuild...I graded all the prebuilds. A good number of teams came afterwards to ask for prebuild tips. Now, I can't divulge the specifics of the rubric. What I will say is this: the most important part of prebuilding is making sure that the shape of your prebuild isn't going to change during transport, grading, and general handling.

One thing I noted was that some teams would use things like stands or string their prebuild to a box top. Nothing wrong with presentation. However, if you're going to suspend your prebuild from something, you're going to have to secure it from all angles. You really don't want gravity coming in and possibly deforming your build; aim for as few degrees of freedom as you possibly can. It's also a pain (on the part of the grader) to have to maneuver and untangle while grading, and you can and will lose points for that. If you are going to suspend it from a display, make sure that you have strings attached from the bottom and the top so that we can rotate it without too much harm to the prebuild or inconvenience to us. I saw a really nice suspended prebuild. It was attached to two pieces of wood, and the strings were pulled so taut I could freely rotate it without worrying at all about harming the protein. (The same idea goes if you decide not to use a display; make sure you have supports and things. I handled a few lone toobers that bounced whenever I picked them up.)

Most prebuilds were decent. Most common "room for improvement" was basically refining the tertiary structure and making sure the model looks like the jmol from all angles.

I also got some questions about creative additions, or specifically ideas for them. Very important note: "hydrogen bonds", "N/C termini", "alpha helices", "beta sheets", etc do not count as creative additions. When you think about creative additions, think about things unique to AcrII4A. Creative additions are kind of like extra credit. Every protein has hydrogen bonds, and you're expected to model secondary structures in your model to get the non-extra credit points. They are not creative additions.

Conclusion
Not much. I welcome any questions/comment about my exam, GGSO PMod, or just PMod in general.

Mandatory reminder that 1) there is a new scoring rubric (20/40/40) and that 2)you are allowed only 1 piece of cheat sheet for this exam.
Div D! I really like chem, oceanography, and nail polish--not in that order.
