The scientists in this study wanted to know if cars parked in shady parking lots emit fewer gases than cars parked in sunny parking lots. If that is the case, it would give people another reason to plant trees in parking lots, especially where the climate is hot.

Scientists sometimes design their experiments so that they can compare different things. In this experiment, the scientists wanted to explore some of the differences between parking lots that are shaded and parking lots that are not shaded. When scientists compare different things, they carefully identify what is similar about and different between the things. (What do you think is similar about and different between these two parking lots?) Scientists then take the same kind of measurement from each thing to see if there are differences. In this study, the scientists were interested in the temperature of each of these two areas.

Cars use petroleum as a fuel that runs their engines. When the fuel is burned, its energy is transformed into hot gases that leave the car through the tailpipe. The form of the energy in liquid petroleum is different than the form of the energy that comes through the tailpipe. None of the energy is destroyed in the burning process, but it is more spread out and less useable. Burning petroleum as a fuel is an example of the First Law of Energy. This law states that energy cannot be created or destroyed. No matter what kind of energy you can think of, it has to obey this law!
