Investigating the Green House Effect

You are a citizen concerned about the greenhouse effect and decide to do some research about the issue. You come across a great website that has a simulation on just this topic. Once you have run some simulations and made some observations you become more than concerned, you are downright outraged! The next step is to write a letter to the editor detailing your concern and using what you have learned as evidence in support of your position.

• 1. Go to http://phet.colorado.edu/en/simulation/greenhouse

• 1. Open up The Greenhouse Effect and explore all of its features.

• 1. Write down your observations of what happens during the three featured time periods: Today, 1750 and Ice Age.

• 1. Change the number of clouds for each time period and write down your observations.

• 1. Scientists predict CO₂ levels to increase to 490 – 1260 ppm by the end of the century. Run a simulation that will help you predict how this change will affect temperature. What do you find?

• 1. Write a letter to the editor detailing your findings.
