Introduction
Lab 6 built off of Lab 5 in using IR on different objects. Instead, the purpose of this lab was to focus on the effects of different types of insulators. As the water cooled down, the temperature of the planes and water was monitored, to show the effects of each insulator enclosed in a warmer object/substance.
Methods
The lab had the goals of measuring the effects of insulation on frozen model airplanes, while using a Sous Vide precision cooker. Four model planes were placed into a bag without air, bag with air, wool sock in a bag and the fourth plane at room temperature inside a bag of air. The four bags were then placed into a container filled with boiling water, while the camera filmed. As time passed, the videos recorded the effects of cooling and warming.
Discussion
Below, a link is provided to the videos that were recorded during the lab. The video named "DJI_0003.mov" shows the planes and water in IR, while "DJI_0004.mov" shows the objects in RGB.
As the videos go on, it can be observed that the planes, within the IR video, slowly change into a lighter black. When it starts lightening up, it means that the planes are warming up. Comparing all the planes, the plane that was placed inside a bag without insulation warmed up the quickest. Since there were not many atoms between the plane and the boiling water, it did not take as long to heat up the atoms of the airplane.

Conclusion
As briefly mentioned above, any type of atoms, whether it be air or a sock, act as an insulator for the object being observed. Since there was one model airplane without any true insulation, it caused it to increase temperature rather rapidly. This lab was very useful in finding the effects of insulation and how IR visualizes infrared radiation. Lab 6 gave even more insight of the real world and the world of IR.
