Julie took her lunch to work every day. She wanted to know what type of insulation would keep her lunch the coolest. Each day, she took her lunch in a different container: a Styrofoam cooler box, a plastic cooler box and a soft insulated lunch bag. She measured the temperature inside her lunch container every day at noon. She repeated this process for 9 days. In the end, she knew exactly which lunch box to use to keep her lunch the coolest.
