<p>Earth Sciene 11 Name______Mr. Matty 2014 Date ______</p><p>7.1b Activity - The Greenhouse Effect</p><p>Discussion: There are factors that may influence weather patterns and climate and their effects within ecosystems (for example: elevation, proximity to oceans, prevailing winds, fossil fuel burning, volcanic eruptions). You will be looking at the effects on our atmosphere that can occur due to some of these factors.</p><p>Learning Goals: Students will analyze how Greenhouse Gases affect Earth’s temperature and identify processes that might increase or decrease Earth’s temperature.</p><p>Go to: http://phet.colorado.edu/new/simulations/index.php</p><p>Click on “earth science”; Click on “The Greenhouse Effect” When the program asks how you would like to get to Earth, choose the Fly Me in Option.</p><p>Ice Age:</p><p>1. Click on the “Ice Age” button and record the minimum temperature. ______</p><p>2. Record: CO2 _____ 3. What happens to the sunlight photons as they hit the ground? ______</p><p>______</p><p>4. Are all of the sunlight photons being reflected back into space? ______</p><p>5. What happens to the temperature when you add clouds? ______</p><p>______</p><p>6. How are the photons affected by adding clouds? ______</p><p>______</p><p>1750:</p><p>7. Click on the “1750” button and record the minimum temperature. ______</p><p>8.

How are the photons affected by adding clouds? ______</p><p>______</p><p>Turn to your neighbor and describe how the Greenhouse Gases affected Earth’s atmosphere during the Ice Age, the year 1750 and Present. </p><p>What would happen if there were no Greenhouse gases? (Adjust the Greenhouse Gas Concentration Level to None.)</p><p>______</p><p>______</p><p>What would happen if Greenhouse gases increase? (Adjust the Greenhouse Gas Concentration Level to Lots)</p><p>______</p><p>______</p><p>Identify some natural or human processes that might increase or decrease the amount of greenhouse gases in the atmosphere.</p><p>______</p><p>______</p><p>______</p><p>______</p><p>______</p><p>______</p>
