This activity shows students that decisions they make can significantly alter the amount of greenhouse gases they release to the environment. Students make back-of-the-envelope calculations to estimate the amount of carbon dioxide released to the environment by different autos. The students also learn about exponential growth by calculating how the money saved by purchasing an inexpensive car can be invested to great advantage.
