Earlier this semester the 2nd graders tested the temperatures of different materials around the Science Lab trying to find out which made the best insulators or conductors. They used that knowledge to create homemade coolers that had to keep ice pops frozen for 40 minutes. If they succeeded, then they got to eat the ice pop!
