Rooftop Gardens
It was another hot day, but we’re starting to cool off. The heat was actually a benefit to our experiment. Each group made two identical buildings out of foam core and duct tape. On the roof, each building was covered in black sand paper (to act as a black tar roof). One of the building’s roofs was then covered in plastic and then sod. The sod was used to emulate a rooftop garden. Using a thermometer, we then tracked the temperature for 10 minutes and recorded the differences. As expected, most of the groups found the temperature of the buildings with the black roofs to be higher than those with the gardens. For a fun add-on, we also used our invention skills to build a device that could reach a treat that had been taped to the wall about 8 feet up. Each group could only use 2 sheets of newspaper, tape, 5 paperclips, and a cup.
