To conclude this element, the design and development of the Polar Pillow has taken 8 months and multiple instances of different mathematics, technologies, engineering practices, and science. Some of these exact STEM Principles have been chemistry, weight measure machine, infrared thermometer, dimensioning, drawing in inventor, survey percentages, and ratios. The development of the Polar pillow has been greatly accelerated  by mentors and experts they have helped with understanding rem sleep cycles, engineering techniques for testing, and chemistry. Finally the team has divided up responsibility and their team norms have focused on communication and establishing tasks that need to be done.
