• After viewing the video ask students the following questions: What new information did you learn from the video? What information surprised you? Why? What was the most important or interesting information that you heard? Explain your thinking. How can you relate this information to your own life? How can you apply this information to the world around you?
• Before watching the video introduce the following vocabulary words: air mass, anemometer, atmospheric pressure, barometer, climate, front, isotherm, hydrology, hygrometer, humidity, meteorology, turbulence, weather. Instruct students to jot down definitions of these words as they are viewing the video.

Using a Ziploc bag, water and blue food coloring have students pour 1/4 cup of water and a few drops of blue food coloring into bag. Seal tightly and tape the bag to a (preferably south-facing) wall. As the water warms in the sunlight the water will evaporate into vapor. As the vapor cools, it will begin changing into liquid (condensation) just like a cloud. When the water condenses enough, the air will not be able to hold it and the water will fall in the form of precipitation.
