Hi Zack
to insulate your houses,, you can use the same materials. There is builders foam with different "R" ratings and you can use it or you can use egg crate stuffed with bubble wrap (small bubble) to fill to back side voids.
For a heat source you can use a 40 watt light bulb and in the cold house, a refrigerator light bulb (20 watt). To illustrate the cold house you can also use florecent bulbs which are much cooler. Use blue ice to keep the cold house cold.
For windows, you can use plexiglass of 3 layers with a small air gap between the layers. wrap the "assembly" in clear plastic bag like a Ziplock bag and suck out the air. This makes it more efficient as an insulator. Install the windows at the two ends of the box.
Line the inside of the box with the insulation of choice including the floor and top.
Place the blue ice into the box and then take measurements of the temp inside and out side of the box. Do the same with the hot box. You can not keep the hot box on too long due to the b uild up of heat, may cause a fire.
