1. Do Now! Compare your work on E55 Graph to this example. E55 AQ 1a. Create a graph of the data you collected. Remember to label your axes, title your graph, and include a key. 1b. Summarize the trends that you see in a graph. Time (Minutes) Differences in Heating Earth Surfaces: Sand vs. Water (Example Graph) Temperature (◦ C) No title = -2 Partial title = -1 No label = -1 No units = -2 No label = -1 Overall Graphing = -1 Uneven intervals -1 Inaccurate plots

2. Date: 3/6 (A) & 3/7 (B) Outcome: Students will understand that weather is a result of complex interactions of Earth's atmosphere, land and water, that are driven by energy from the sun. Questions: How has Earth’s climate changed over time? (E65) Has the Earth’s atmosphere always been the same as it is today? (E65) What role does the atmosphere play in weather and climate? (E66) Activities: Do Now!

4. Earth’s Atmosphere http://www.sepuplhs.org/middle/iaes/students/simulations/sepup_atmosphere.html http://www.sepuplhs.org/middle/iaes/students/simulations/sepup_atmosphere.html Gases in atmosphere: Nitrogen (78%) Oxygen (21%) Carbon dioxide, water vapor and argon (1%) Layers of atmosphere: Exosphere (120 km+) merge to space Thermosphere (80 – 120 km) space shuttle Mesosphere (50 – 80 km) meteors burn up Stratosphere (12 – 50 km) ozone absorbs some UV radiation from sun Troposphere (0 -12 km) most weather and aircraft

5. Prevailing winds When the winds blow from one direction more than from any other and this pattern can influence global climates.
