Experiment 4 - Photon Absorption

In this experiment, you will investigate the interaction of individual gases in our atmosphere with both incoming solar radiation and outgoing terrestrial radiation.

Experiment procedure:

On the simulation screen, select the Photon Absorption
In the Atmospheric Gases box, select the button for CH₄ to put a methane gas molecule in the middle of the screen.
Underneath the photon gun, select Infrared Photon. This loads the gun with infrared photons.
Using the slider on the gun, shoot at least 20 photons at the molecule.
As a photon is emitted from the gun, it may pass through the molecule, or it may interact with the molecule. When a photon interacts with a molecule, document what you observe happening. If no photons interact with the molecule, document that as well.
With the gun still loaded with infrared photons, repeat steps 4 and 5 above for the other four gases in the Atmospheric Gases box - CO₂, H₂O, O_2, and N₂.
Underneath the photon gun, select Visible Photon. This loads the gun with visible photons.
With the gun now loaded with visible photons, repeat steps 4 and 5 above for all five of the gases in the Atmospheric Gases box.

After completing the experiment:

In the submission template document, under Experiment 4, Observations and Data, enter your observations from step 5 of the experiment for all five gases for each type of photon.
Based on your observations from the experiment:
- State the evidence that water vapor (H2O), carbon dioxide (CO2), and methane (CH4) are greenhouse gases.
- Formulate a written discussion that describes how oxygen and nitrogen (the two primary components of Earth's atmosphere) interacted with both incoming solar radiation and outgoing Earth radiation.
- Explain how your discussion in the previous two bullet points connect to the observed paths of both solar radiation photons and infrared photons in experiment 1 for Today's atmosphere.

Enter your discussion for the previous three bullet points in the submission template document, under Experiment 4, Conclusions.
