I'm still trying to learn as much as I can. We are going to state soon and it would be better this time if I could know as much as possible along with the binder.
Are there any good sites or books on thermodynamics and vocabulary. Please and Thank You!

Would puffed wheat (The non-sugar kind you can buy in cereral isle of the grocery market) be okay in the device?
My kids kept ripping the aluminum foil out of their device so we opted for foil tape . . . what is everyone's thinking here on it? Legal? Not legal?
Finally, so according to the national rules clarification, they can bring a thermomter and test the water temperature right after it has been inserted into the device, correct?

That was screwed up...but we couldn't do anything, because it was all technically within the rules. My Regionals tournament, however, was much...better.
At Regionals, they took up the plots as they were giving us water.
At State, we had to predict the temperature of water using given information, what they called "dry labbing". Even though we still tested, that prediction was the first part of our test, and we had to turn in our plots as proof that we had it and we were not just completely making it up.
So it varies. Just...be prepared for all scenarios. Or at least, as many scenarios as possible.

As I've done in the past, I'm soliciting suggestions for rules changes for Keep the Heat / Thermodynamics. Please don't just say "I don't like XXXX", but rather make concrete suggestions (i.e. "Change XXX to YYYY" or "Remove ZZZZZZ" or "Add WWWWW"). I can't promise you we'll actually implement your ideas, but they will be noted and passed on to the rules committee for discussion.
For this event, I'd say standardizing the transfer of water would be nice. I liked the invitationals where the ES already had the water measured out (i.e. 50 ml in a baby food jar) and being heated rather than the invitational where they had a large volume of water being heated, and took 2 minutes to measure out exactly the volume neede for both beakers. In that time, the temp went from 71 to 55... Threw off my prediction completely.
In short, possibly outlining exactly what to do during the transfer so that teams can practice that way and it won't be open to interpretation.
