How does a thermos bottle minimize heat transfer? Investigate how heat loss due to convection, conduction, and radiation is prevented by looking at the design of a thermos. Compare cheaper versions to the design of more expensive versions and explain the differences in terms of the concepts used in the mechanism of heat transfer.

While riding the other day a large healthy female Coyote tracked along with me and my horse. She stopped when we stopped and was watching us and was very calm. At one point she moved in front of us, stopping ever several hundred yards to turn and look as though waiting for us. This lasted for over a mile until I returned home and went inside the fence, she watched us a bit longer and then returned the way she came. I've been an outdoors person my entire life and have never had an experience like this.....
