This model simulates the effect of solar radiation and albedo on temperature. Click "Edit Camera" and right-click and drag to tilt Spaceland so you can view the model in 3-D.
In this extension, cars are created which drive for a certain time and have a 5% chance of emitting CO2 at each tick. The CO2 interacts with the heat in the same way as in the factory model.
This extension also adds buses, which run for the same time and move in the same manner as the cars.
Each bus emits twice as much co2 as each car (is twice as likely to emit a co2 each tick), and each . bus created takes 10 cars off the road. These are random numbers -- to make the model more realistic, research how much co2 buses emit compared to cars, and how many students typically ride on a bus. Then, experiment with how the number of students riding a bus changes the amount of CO2 emitted.
