a. Make general overview of the issue (corrections to your sketch?) Light in the form of radiation is delivered from the sun to the Earth. These light photons pass through the atmosphere, after which some are absorbed as energy by the Earth. The infrared particles are not absorbed, but instead reflected back in all directions away from the Earth. However, when the Earth’s atmosphere has greenhouse gases, these reflected infrared particles are again reflected back towards the Earth’s surface. In this way, these particles become trapped between the Earth and its atmosphere, causing the planet to heat up. It is important to note that when the Earth’s atmosphere contains no greenhouse gases, the infrared particles can escape and the Earth is not heated.
b. Do you know enough about the atmosphere? I have a basic understanding of what causes the Greenhouse Effect. However, I do not understand some components of this process. For example, why is it only that the infrared particles are reflected back? Also, why can these particles enter the Earth, but not escape the atmosphere. Therefore, I would need to learn more about this topic before teaching pupils.
c. What are the main things affecting the phenomena: Concentration of greenhouse gases
Types of gases that make up the atmosphere
Amount of photons from the sun
To some extent, amount of cloud cover

d. Run the simulations at least when there are: gas concentration is none and lots, 1750, and today. Report your observations. When gas concentrations are low, the Earth’s temperature hovers around -20C. As the concentration of gases increases, the temperature of Earth also increases. Furthermore, at higher concentrations of gas, the temperature rises at a faster rate. Finally, when the concentration of gas decreases, the temperature also drops to its original levels.
