Ice ice baby

Room 5 have completed their science fair projects. The 'Ice ice baby' group decided to do an experiment about how colours absorb and reflect heat. We wanted to find out whether lighter or darker colours absorbed the most heat. We found this out by placing an ice cube on different coloured pieces of paper and seeing which ice cube melted the fastest.

Our question was: "What colour conducts heat and makes ice melt the fastest?"
Our hypothesis was that we thought the black would melt the ice faster than the other colours, but it turned out that the the white made the ice melt faster.

Dark colors absorb more heat than light colors, causing a dark surface to become hotter than a light surface made of the same material and exposed to the same heat source. Lighter colours reflect heat, so the light went through the ice, hit the white sheet of paper and reflected back through the ice, which is why white was the fastest.

We had Teachers from Nayland College to Judge our science fair boards and ice ice baby got Highly Commended and Mrs Parker judged our boards and ice ice baby got the best score in the class 17/20!! Yay!!
