Lesson 3: Heating Earth’s Surfaces Students investigate, graph, and analyze the uneven heating and cooling rates of soil and water. Warm surfaces radiate heat energy and warm the air above them. Cool surfaces absorb heat energy and cool the air above them. Lesson 4: Heat Transfer and the Movement of Air Students manipulate the temperature inside a clear cylinder to investigate the effect that surface temperature has on the temperature of the air above it. Using smoke as a flow indicator, students also investigate the effect that surface temperature has on airflow. The upward movement of warm air and the downward movement of cool air form convection currents, which move heat through the troposphere. Fronts form at the boundary between two air masses with different temperature, pressure, and humidity conditions. Lesson 5: Convection Currents in the Air Students connect two cylinders and observe the formation of convection currents. Then they relate their observations of air movement in the lab to weather fronts and the formation of winds. Precipitation, thunderstorms, tornadoes, and hurricanes often develop in weather conditions (or when warm and cold air masses meet). Lesson 6: Temperature, Pressure, and Cloud Formation Students use sealed bottles of water to investigate the conditions under which water evaporates and condenses. They manipulate the air pressure in these closed systems to determine the effect of high-and systems on cloud formation. Then they apply their observations to weather maps and draw conclusions
