Finding Good Insulators for our Solar Ovens

on April 29, 2014

Third grade students have been playing the role of engineers in science class.  We are finding ways to design and create a successful solar oven to use outdoors.  This week’s experiment involved testing different materials to see what worked best at insulating the warm air in a cold water bath.    We wanted to see if there was a difference between shredding the material and covering the inside of the cup with the same flat material.  Students collected a wide range of results that seemed to be affected by a variety of factors including the room temperature, the kind of ice used, the amount of water put in the ice bath, and the timeliness in recording the data.  We are also evaluating each material for the  impact it may have on the environment.  This experiment is a great way to learn about design, heat transfer, and environmental engineering.
