Testing Changes to the Atmosphere

Objective: KWBAT test changes to the atmosphere in order to observe how they change the amount of energy absorbed by Earth’s surface.

Part 1

Welcome back climatologists! Yesterday you explored the SIM for evidence as to what is causing ice to melt on Earth’s surface. You discovered that when more ice is melting on Earth’s surface, the amount of energy absorbed by Earth’s surface increases. Today we will investigate ideas about what kinds of changes to the atmosphere can affect how much energy is absorbed by Earth’s surface. Now that we know energy is involved in the rising global temperatures and melting ice, we can finally answer the question of: Why is the ice on Earth’s surface melting? To do this we must learn more about our atmosphere and what is in it!

Part 1: Do Now

The Earth’s atmosphere is about 480 km (300 miles) thick and surrounds Earth.

What is Earth’s atmosphere made of? If you’re unsure, take your best guess!

Why do you think our atmosphere is so important to life on planet Earth?

Part 3: Investigation of Changing Gases in Atmosphere

Goal: Use the SIM to investigate the claim about changing gases in our atmosphere.

SIM DIRECTIONS
Open the ECC Simulation and press play, to run it for 20 seconds.
Increase (+) the Carbon Dioxide to 500.
Run the test until the timer reaches 40 seconds.
Observe the temperature, amount of ice, and yellow glow of absorbed energy.
Record your results in the tables below highlighting your answers. Either increase/decrease/no change.
Reset the SIM.
Repeat steps 1-7 but now decrease the Carbon dioxide down to 0.
Record your results, then REPEAT this entire process again for the 3 other remaining gases!

Carbon Dioxide

When I INCREASED (+) Carbon Dioxide….
energy absorbed by the surface: __________
temperature: __________
the amount of ice: __________

When I DECREASED (-) Carbon Dioxide….
energy absorbed by the surface: __________
temperature: __________
the amount of ice: __________

Methane

When I INCREASED (+) Methane….
energy absorbed by the surface: __________
temperature: __________
the amount of ice: __________

When I DECREASED (-) Methane….
energy absorbed by the surface: __________
temperature: __________
the amount of ice: __________

Sulfur Dioxide

When I INCREASED (+) Sulfur Dioxide….
energy absorbed by the surface: __________
temperature: __________
the amount of ice: __________

When I DECREASED (-) Sulfur Dioxide….
energy absorbed by the surface: __________
temperature: __________
the amount of ice: __________

Nitrogen Dioxide

When I INCREASED (+) Nitrogen Dioxide….
energy absorbed by the surface: __________
temperature: __________
the amount of ice: __________

When I DECREASED (-) Nitrogen Dioxide….
energy absorbed by the surface: __________
temperature: __________
the amount of ice: __________

Synthesize: Based on your data, do all gases have the same effect on the amount of energy absorbed by earth’s surface?

Investigation Claim: A change to any gas in the atmosphere affects energy absorbed by the surface in the same way.

I __________ with the investigation claim. After completing the 4 gas trials in the SIM, I found that all gases  __________affect the amount of energy absorbed by Earth’s surface in the same ways. Therefore, this claim is __________ by my data.

Part 5

Part 5: Exit Ticket

When the amount of carbon dioxide or methane in the atmosphere changes, the amount of energy absorbed by the surface also changes.

When the amount of carbon dioxide or methane _______ , energy absorbed by the surface increases.
When the amount of carbon dioxide or methane _______ , energy absorbed by the surface decreases.

After science class one day, your friend texts you saying, “We will always need carbon dioxide in our atmosphere because that is one part of how plants produce their own food, through photosynthesis. And besides, animals including us breathe it out --so it can’t be all that bad!”
