In this lesson students will learn to understand the following: 1) Infrared rays from the sun enter Earth's atmosphere. The gas carbon dioxide (CO2), which is given off by oxygen-breathing organisms and produced by the burning of fossil fuels, traps the sun's warmth within Earth's atmosphere. This phenomenon is known as the greenhouse effect. 2) The greenhouse effect is important to life on Earth because it provides our planet with the warmth it needs for animal and plant life to thrive. 3) The burning of certain fuels creates excess CO2, which traps even more heat within Earth's atmosphere, possibly creating a phenomenon known as global warming, which may be harmful to life on Earth.
