For this lab, the class tested the heat transfer of materials we could have used for our classroom design. This was to determine which materials wouldn't be too hot, after sitting in the sun, for use in our outdoor classroom. We placed the materials under a heat lamp for 30 minutes, taking the temperature every 5 minutes. After 30 minutes, we turned off the heat lamps and continued taking the temperature every 5 minutes. Once we reached 80 minutes total, we stopped the lab.
