Make hot-cocoa & take it outside: throw a temp-probe in there. See if
you get exponential cooling.
Compare insulated containers using hot cocoa & T probes.

Subject: [Phys-l] Physics Day snow tubing
Greetings everyone. It's been a while since been on here. I hope
everyone has a nice holiday season.
I was wondering if some of you could help me? Last year, I took my
niece and nephew snow tubing at our local ski area. During our tubing,
I realized that this could be a fun and educational experience for my
Physics students. In the years past, I've taken them to Cedar Point
Amusement Park for their Physics Day, but because we had several
experiences with bad weather and because of budget cuts, we stopped
going. This ski area is local, cheaper, and I figured the weather would
be more consistent than going in the early spring to a park. I
contacted the owner and manager with the idea of a Physics Day at their
ski area and they welcomed the idea.
What I'm wondering was if anyone has ever done this? If so, could
anyone provide me with any ideas, labs, or suggestions of how to make
this a successful experience? Any advice or material would be greatly
appreciated!
