I was on the "B" Team at Regionals and got 1st in CJP with my partner.
Then at states, the state team (which I was not on) got 1st in CJP also (our only medal at states).
Our way of practicing was just running the tests and questions over and over and we kept correcting the ones we got wrong. I think it was pretty good since we got 1st in states and regionals. One time the CJP teams stayed until 8:00 PM at school to practice (and I was one of them).
I wonder if the CJP event graders even check the observation sheet when they see the part that says, "Which observation numbers support this question?" I accidentally wrote exothermic on the observation sheet instead of endothermic, and then on the question sheet I wrote endothermic and wrote the # for the observation which said exothermic. Strange.
they do check it, but it's is strange that they didn't notice your mistake, it might be that they missed it or they weren't able to understand your handwriting.

How did you state its endothermic or exothermic without it being an inference?

oh wait thats right
NYHSLVSSO
you can't just write its endothermic or exothermic on the observations because that is not an observation
you have to write the temperatures

Yes, what I wrote as an observation was:
When the powder was placed in the water and stirred, the temperature went from 22 degrees C to 24 degrees C, inferring it is endothermic.
That was the mistake. (Anyway, that's the way you're supposed to write a 5-pt observation because I did some looking around on the Soinc.org website.)
Then, the question said, "Did the powder dissolve into the water endothermically or exothermically? I wrote:
Exothermically. Observations: #X (which is above)
The coach said that if we make on small mistake then we might get bumped down to sixth place or something.

well you wrote the temperatures and that is all that matters
and if the answer was correct then you have the temperatures to prove it.

If you must state its exothermic or endothermic, do so in the answer, not the "observation".

At Nationals, there was no answering of the question. The Exothermic and endothermic thing when you write inferring wasn't what the Nationals proctor wanted. On her test, you had to basically write the question number on the observation sheet instead of vice versa. It was quite interesting.

On our test you had to answer it and write the observations. You get 1/5 points for answering it with no observation.

So first we did tests with observations, then we answered the questions. I think we got 1/2 points for answers no observ. But I dunno.

Yeah they give around 2-3 points for answers without observations. Also, the goal of this event is to write complete observations. That trip us up at state and after we went over that, we did a lot better (medal at nationals). So the number of observations doesn't matter but they have to be complete and full, since you were only allowed to mark 1 observation per question.
