Can't Judge a Powder B

[samlan16]

So, I'm from Minnesota, State's tomorrow. Should I bring test tube stoppers?

I don't know anymore, so use your discretion.

I guess I won't. Better safe than sorry.

What purpose do they have? It's not like anything will explode on you, and poking the things give as much effect as shaking them up.

Hello ////
I am doing Can't Judge this year, and our state CJAP observation sheet was sketchy.
It had us record our observations as usual, however next to the observation, we had to write "how we got the observation", kind of like a mini procedure.
I've never heard or seen anything that required us to do this, so we weren't really sure what do write (like how detailed etc) plus we were running low on time, so I scribbled some short (and probably too short) things down.

I was wondering if anyone else had encountered this, and if so, what the standards are for a good "mini procedure".
Idk what else to call it lol ;-; Thank chu

What a shame... For an event supervisor at the state level to inject their own personal twist on the rules that has been unpracticed by all for the entire year is just sad... So sorry you had to go through that...

This was mentioned earlier in the thread but I think it's worth revisiting:

How much quantification is really possible, assuming the ES provides the bare minimum (NaOH, HCl, water, waste container, and nothing else)? If students have practiced with a "scoop," which would be the better observation: A) "One scoop of the sample completely dissolved in 1.0 mL of water with gentle stirring" or B) "Approximately 0.1 gram of the sample completely dissolved in 1.0 mL of water with gentle stirring." If I were the ES, I'd go with A - it was less quant-y, but a better observation. "Observation" B in the example relies on an estimation, based on an inference, based on prior observations at some point with a scale. I'm just suspicious that some ES would, using a "quick-and-dirty" rubric, weight B higher, because at first glance it contains more numbers.

What other quantifiable observations are being made? Is it enough to describe conductivity of a solution as "strong" or "weak" based on how brightly an LED appears to glow, or would it be better to avoid using those sort of modifying words, since they're meaningless without a reference comparison? Also, how closely are student observations scrutinized to make sure they're, well, real? It's totally plausible that students could write an observation that they didn't actually make (clearly in defiance of "spirit of the rules" but how is it caught?).

We've been struggling to up the quantification in observations - is it legal to use time? Are students allowed to use a watch, or the clock in the room? Is an observation such as "When 1.0 mL of HCl was added to the substance, a fizzing sound was audible at a distance of 15 centimeters from the ear for a duration of 4.4 seconds" any better than ""When 1.0 mL of HCl was added to the substance, a fizzing sound was audible" ? How the students would justify writing 15 cm, I'm not sure - maybe they knew their test tube was approximately that length and estimated? If they used a timer on their watch, the duration part could be justified, but, not every team would have equal access to that since stopwatches weren't explicitly permitted. First-year coach, first-year team, first-time post - thanks for your consideration!

That actually happened to me once. If the person conducting experiments is done, have them do the mini procedure because you
have too many things to write.

Does anyone have the raw scores for nationals?
