Is one of the goals to achieve the minimum change in heat/temp loss using the device AND predict the change OR is JUST the prediction in the change in temp considered in the final score? Also what exactly does the "heat score"/ k value mean?

Sorry. I'm pretty much a noob :P
It took me a lot of time to understand the rules too.
Final Score out of 100 = (Heat Score/20)+(Prediction Score/25)+(Test Score/45)+(Chart Score/10)
So yeah, minimum change in heat AND predict the final temp
k is from newton's cooling law

Should the insulating device be relatively thin or thick??

as Thicc as possible

Lmao yessss
Yeah but make sure you leave space for the beaker

^Thanks for the responses above guys! Anotha one (sorry): should they device be relatively light or heavy and WHY??

The weight depends on the materials used to build it, which should be chosen based on their thermodynamic properties. There is no specific weight requirement in the rules, so it just depends on how you make it.
(I will note that very good insulators are typically rather light...)

Weight actually plays a factor in the device build, but most devices are all around the same weight. I would recommend not worrying about weight and focusing on the material.

I third this fact as weight is completely irrelevant. You should focus on the material. The ES won't care if you bring in a solid gold box with foam as long as it's within all the rule requirements. :lol:

I say the device should be pretty light; most all good insulating materials rely on air's low conductance, and so (because they are mainly composed of air) will be light. For example, insulators such as foam, cotton, and even Aerogels rely on air in order to insulate, and so are superlight.
So due to the fact that efficient thermodynamic insulators are, in general, light, so should be your device.

Does anyone know what score was placing at MIT?
