Yesterday the 2J students were all given a challenge: To keep an ice cube frozen for an hour. They were to use their knowledge about insulation and insulating materials to create a thermos that would keep their ice cubes from melting. Each student was given 2 styrofoam cups, 8 cotton balls, 4 tissues and masking tape. They needed to design and assemble their “Keep-It-Cool Devices” yesterday, and we tested them today. Below is a slideshow of the 2Js working on their devices, each student’s completed device, as well as what their ice cubes looked like 1 hour and 5 minutes later. Way to go, 2Js!
