I would prefer that all the data is put on a single plot with three different curves. Make a numerical estimate of the thermal conductivity of one of the containers. Describe the demonstration you have devised to convince a skeptical audience that heat is indeed transported by a radiative process at Station 2. Show your calculation of the heat flow from the freezer in one hour. You may look up any material characteristics that you need but be sure and present all of your numbers.
Thermal conduction is the primary process by which most hot beverage containers lose their heat.
At this station you will find fluid containers that are made of different materials to illustrate the effect this has on heat loss. The time of the measurement. We can get warm near a fire without actually crawling into it. In fact, there is the problem that the parts of you that don't face the fire tend to get cold while those that do face the fire can get overly warm. The movement of heat is accomplished by radiative transfer in these cases.
