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.

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

Question 12

Question: How do greenhouse gases affect Earth’s climate?

Examine the graphs below representing different times of the day with greenhouse gases set at 10%.
T (°F) represents changes in temperature measured in degrees Fahrenheit
Heat flow represents changes in heat going in and out of the atmosphere
Midnight

6 PM

What do you notice about the heat flow into and out of Earth's atmosphere over the course of a day?

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

Examine these graphs where the greenhouse gases have have been eliminated (0%).

 How have the variables changed with the decrease in greenhouse gases?
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 for the first 3 gasses.

Methane CH4

Blocks heat from escaping the atmosphere.  Warmer air holds more of it and as Earth heats up, it traps more heat.

Water vapor H2O

Released when burning fossil fuels

Carbon dioxide CO2

Second most important contributor to global warming

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 for the last 3 gasses.

Nitrous oxide N2O

In the atmosphere, protects us from UV rays but acts as a GHG on the ground  

Chlorofluorocarbons (CFCs)

Released by factors, power plants, and fertilizers and damages the ozone layer

Ozone O3

Man-made gases that damage the ozone layer

Question 10

10.

Please evaluate your performance on the learning targets

I need help

I am getting there

I got this

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. 

How is the Earth's atmosphere similar to a green house?

They both trap heat

They both release heat

They both protect
