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!
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?

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.

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

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!”
