During this lab we tested the heat transfer onto materials we would be using. This lab showed us which materials might over heat being in the sun all day and uncomfortable in use. We had heat lamps and set all the materials under them for 30 minutes. We checked on all the materials every 5 minutes. After 30 minutes of tests we turned off and put away the lamps but continued to track the heat of the materials for 50 more minutes, having tracked data for 80 minutes in all.
