• Pretest

Students will use Google Earth to explore global temperature changes. They will use Google Earth to determine how the temperature of the Earth has changed during a recent 50 - 58 year period. They will also explore, analyze, and interpret climate patterns of 13 different cities, and analyze differences between weather and climate patterns.
 
Students will be introduced to the four main Earth spheres (atmosphere, lithosphere, hydrosphere, and biosphere) and the structure and composition of the atmosphere. Students will also understand the different roles that ozone plays in the troposphere and the stratosphere.
 
Students will explore the variety and ratio of compounds and elements that make up the Earth’s atmosphere. They will understand volumetric measurements of gases in the atmosphere and visually depict the composition of the atmosphere.
 
Students will be introduced to the major sources of greenhouse gases. Students will understand that greenhouse gases are produced by both natural and anthropogenic (man-made) sources.
