Question 1
1.

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 2
2.
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.

Question 3
3.

Question 4
4.
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? _______

Question 5
5.
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?

Question 6
6.

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?

Question 9
9.

How is the Earth similar to a green house?

Question 10
10.

In your own words, explain how the greenhouse effect works.

Question 11
11.

Bonus Science!
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.
Predict: When you change the amount of greenhouse gases in the atmosphere, which factor(s) do you expect to change?
Heat flow in
Heat flow out
Temperature
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?
Earth releases less heat back out to space
Earth releases more heat back out to space
No change in the amount of heat released 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
Carbon dioxide CO2
Blocks heat from escaping the atmosphere. Warmer air holds more of it and as Earth heats up, it traps more heat.
Chlorofluorocarbons (CFCs)
Released when burning fossil fuels
Nitrous oxide N2O
Second most important contributor to global warming
Methane CH4
In the atmosphere, protects us from UV rays but acts as a GHG on the ground
Water vapor H2O
Released by factors, power plants, and fertilizers and damages the ozone layer
Ozone O3
Man-made gases that damage the ozone layer
Please evaluate your performance on the learning targets

Learning Target 1: I can Describe how greenhouse gases warm the atmosphere
Learning Target 2: I can Identify and Describe one factor that impacts the greenhouse effect.
Learning Target 3: I can Explain the cycle of heating and cooling in the Earth's past.
