Introduction:
The purpose of this lab was to show how heat dissipates through different insulators. To do so small 3d printed airplanes were put into bags and submerged in water being heated by a sou vied machine. These airplanes were then filmed using an Infrared camera mounted on an Unmanned Ariel Vehicle.

| IR image of bath |
The planes were kept in plastic bags, one in a bag with air and the other without air in addition to one of them being chilled and the other being room temperature. From there IR video was recorded from the UAV, as well as pictures taken over time to view the rate at which the different insulators effected the temperature of the airplanes.
Discussion:

| Regular image of bath |
Over time the airplanes started to heat up, the airplane in the bag with air takes longer to heat up due to the air acting as an insulator, as well as the plastic of the bag. The regular bag takes much less time as there is only the plastic as an insulator, and the cold plane takes more time to reach the bath temperature as it's thermal energy energy dissipates into it's insulators and keeps it cooler longer.
Conclusion:
When taking IR footage it is important to know how insulators work. If you are trying to observe a change in an object, or see how efficient an insulator is, you need to understand how the different temperatures appear on an IR camera. By knowing how the different shades show temperature you can observe these changes very easily with the equipment provided.
