@j azmaleia Answered 2 minutes ago . The yellow stars represent the sunlight photon. The red stars represent the infrared photon. . The approximate temperature "inside the greenhouse" before adding glass panes is 250K or -1OF. . The sunlight photons will pass through the glass going down to the earth's surface. . The infrared photons will bounce back and forth from the earth's surface to the glass going back to the earth's surface. Minimal infrared photons pass through from it. . The new temperature is approximately 302K or84E . The infrared photons are bouncing back and forth from the glass layer to the earth's surface which makes the temperature higher. . The temperature when additional glass panes are added goes higher. . As the glass panes increase, minimal infrared photons escape from the glass pane compared to the infrared photons trapped. Explanation: . Steps and Procedures: 0 Open PhET Interactive Simulations: Part II: The Earth Simulation 1. Select the "Greenhouse Effect" tab. Which greenhouse gases are considered by the simulation? 2. Which time period do the default conditions represent? 3. The thermometer represents the average global temperature. What is the average global temperature for the "today" simulation? 4. Is the behavior of the photons more similar to the greenhouse simulation with or without glass panes? 5. Reduce the greenhouse gas concentration to "None". Is the behavior of the photons more similar to the greenhouse simulation with or without glass panes? 6. What is the average global temperature? 7. Considering the behavior of the photons, why does the temperature drop so much? 8. Increase the greenhouse gas concentration to "Lots." What is the average global temperature? 9. Considering the behavior of the photons, why does the temperature increase?PhET Greenhouse Effect Objective: Describe how the "greenhouse effect" affects temperature on the earth and to use evidence to support whether the "greenhouse effect" is good or bad for the earth. Introduction: Global warming is perhaps the "hottest" topic in today's headlines. The cause of warming is usually blamed on the "greenhouse effect" or "greenhouse gases." The following simulation will allow you to first examine how the "greenhouse effect" works in a greenhouse. You will then experiment with a simulation of the earth's atmosphere where the concentration of greenhouse gases can be varied. You will use the results of the two simulations to describe how the "greenhouse effect" affects temperature on the earth and discuss whether the "greenhouse effect" is good or bad for the earth. You will compare the levels of greenhouse gases to different periods in the earth's history and examine their effects. Finally, you will examine different molecules that make up our atmosphere and determine which ones are better at absorbing photons. Before diving into the whole issue of global warming, try to picture sitting in an enclosed car on a cold but sunny day ... pretty comfortable, isn't it. Now imagine sitting in that same car on a hot, sunny day. Don't hold that image too long. You'll fry just thinking about it. Now you know why it is so important not to leave children or pets in a car unattended. NOTE: For electronic submission, type your answers in the blocks provided. If you intend to turn in a hardcopy, ensure you have enough room for each answer prior to printing. 1. Hypothesize why the inside of a car feels so much warmer than its surroundings on sunny days. 2.
