In this Earth Science Meteorology lab, students will gain better insight as to what gases make up the atmosphere. They will color in graph paper to represent the 3 main gases, nitrogen, oxygen, and argon. They will then visually represent the trace gases. As part of this activity, students will reinforce math skills by calculating percentages and converting some percentages into parts per million. Students will learn what the 5 greenhouse gases are and what would happen if we didn't have greenhouse gases. This lab goes along with my lesson on the Atmosphere found at http://EarthScience.xyz/Atmosphere.
