Warm-up: What happens to a car that's been sitting out in the sun on a hot summer day? Why does this happen?
Question: How do greenhouse gases affect Earth’s climate?
Open the Greenhouse Effect Gizmo.
Set the Simulation speed to slow
Set the Greenhouse gases level to 10%
Select the Bar Chart tab
Click Play and observe the changes in the 3 bars.
T (°F) represents changes in temperature measured in degrees Fahrenheit
Heat flow represents changes in heat going in and out of the atmosphere
What do you notice about the heat flow into and out of Earth's atmosphere over the course of several days?
Heat into the atmosphere during the day and at night.
Heat out of the atmosphere from day to night.
The diagram below represents the Earth's heat flow.
#1 Heat Flow In: heat coming from the sun
#2 Heat Flow Out: Heat being release back into space from the Earth
#3 Heat Flow Out being interrupted by greenhouse gases, causing heat to be trapped in the atmosphere.
Predict: When you change the amount of greenhouse gases in the atmosphere, which factor(s) do you expect to change?
Click Reset
Select the Table tab, and click Play. Your greenhouse gas concentration should be at 10%
What is your highest temperature during the day?
What is your highest heat flow in during the day?
What is your heat flow out?
Reset your simulation. Change the greenhouse slider to 50%, increasing your amount of greenhouse gases in the atmosphere. How does this change your...
Heat Flow In
Heat Flow Out
Temperature
From the simulation with less greenhouse gases?
Reset your Gizmos. Change your greenhouse gases to 50% and click Play
This time observe the GRAPH tab. Let the simulation run for a few days, What is happening to the Temperature?
Now move the greenhouse gases to 0% and click play, what changes happen to your temperature and your heat out?
The influence of greenhouse gases on temperature is called the greenhouse effect.
Based on what you have seen, how does having a higher concentration of greenhouse gases effect the earth's ability to release heat back out to space?
Use this website to learn about the major greenhouse gases (GHG). Make sure to click on the "cards" to see both sides.
Match the greenhouse gas to the correct description
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Carbon dioxide CO2 | arrow_right_alt | Blocks heat from escaping the atmosphere. Warmer air holds more of it and as Earth heats up, it traps more heat. |
Chlorofluorocarbons (CFCs) | arrow_right_alt | Released when burning fossil fuels |
Nitrous oxide N2O | arrow_right_alt | Second most important contributor to global warming |
Methane CH4 | arrow_right_alt | In the atmosphere, protects us from UV rays but acts as a GHG on the ground |
Water vapor H2O | arrow_right_alt | Released by factors, power plants, and fertilizers and damages the ozone layer |
Ozone O3 | arrow_right_alt | Man-made gases that damage the ozone layer |
In your own words, explain how the greenhouse effect works.
