What Materials Make Good Roofs?

Room 16 has been investigating what materials make good roofs. We experimented with metal (tinfoil), cloth, plastic and wood. We made a roof out of each material and stuck them to walls made from a milk bottle. We tested each roof in different weather conditions. A toaster was used to provide heat like the sun, water from the tap for rain, and a fan for wind. We decided that plastic and cloth were not very good roof material. Alec's group had a roof made of plastic that melted! Metal and wood were better.
