About This Guide Guide Information Providing students with visual media is an excellent way to take them out of the classroom and into the real world. Our programs offer real-world footage, dynamic graphics, engaging dramatizations, and first-person testimonials that keep students interested and help them visualize difficult concepts. More importantly, they reinforce critical learning objectives shaped by state and national educational standards. However, the learning doesn t begin and end when the program does. You can make the learning experience even more effective by using the materials provided in this Teacher s Guide. This guide is divided into the following sections: Fast Facts are designed to give your students a quick overview of the information presented within the video. Before Viewing Activities help identify what students already know about the subject, what they are curious about, and what they hope to learn. During Viewing Activities may be used during viewing to enhance students understanding of the video. After Viewing Activities help students summarize and draw conclusions from the information that was presented. After Viewing Quizzes test students retention of the information presented in the program and activity sheets. Additional Resources are designed to help you extend the information presented in the program into other areas of your curriculum. Answer Keys are provided for relevant activities or reproducible pages. Script content is provided in an unabridged version for future reference.

Program Overview Guide Information Clouds Video Quiz provides a comprehensive look at this topic. Students explore the important role clouds have for our Earth, the main types of clouds and how to distinguish between them, and factors that are required for clouds to form. In addition, students will investigate the importance of clouds to weather forecasting and where specific clouds are located in the various layers of the atmosphere. The on-screen quiz summarizes information provided in the video. Viewing Objectives By viewing the video and engaging in the activities provided, students will be able to: Name and describe the layers of Earth s atmosphere. Name and describe the basic cloud types. Use measurable terms to show how clouds change and how clouds are classified. Use measurable terms to show how meteorologists use clouds to determine weather patterns. Describe the relationship between clouds and precipitation. Correlation With the National Science Foundation: Students should develop an understanding of structure and function in living systems. Students should develop an understanding of changes in Earth and sky. The sun, moon, stars, clouds, birds, and airplanes all have properties, locations, and movements that can be observed and described. 6 Clouds Video Quiz Sunburst Visual Media, a division of Global Video, LLC

Cloud Fast Facts Fast Facts Clouds bring all kinds of different weather conditions. Clouds are important to our Earth because they bring rain, relief from hot sun, and temperature changes. The four layers of the atmosphere are the troposphere, the stratosphere, the mesosphere, and the thermosphere. Clouds form and become active in the troposphere, from the ground to 7 miles upward. Small amounts of water vapor are found in the stratosphere, which extends from 7 miles to 30 miles upward. The mesosphere is very cold, about 90 degrees below Fahrenheit. The thermosphere is about 50 miles upward and is extremely hot, with temperatures ranging from 930 to 3,000 degrees Fahrenheit (due to the sun's radiation). The two factors that affect the formation of clouds are moisture and temperature. The three basic cloud types are cirrus, cumulus, and stratus. Cirrus clouds are curly or stringy and occur very high in altitude. They are primarily made up of ice crystals and their location indicates a distant storm whose cold winds have created them. Cumulus clouds occur at a low level and are lumpy and clumped together. Stratus clouds occur at a low level and are a thinly spread layer that occurs just after a fog has lifted. Cirrus clouds sometimes break into small, fluffy pieces, called cirrocumulus, which occur 3 miles above the ground and indicate an approaching front. Altostratus clouds are stratus clouds that have thinned out slightly and risen to an elevation of up to 3 miles. Their presence indicates rain or snow for a long duration of time. Stratocumulus clouds are formed when stratus clouds become fluffy and heavy and stay at a low elevation. These clouds indicate a cold front is moving in. Fog is a low-forming stratus cloud that is very close to the ground. Altocumulus clouds are formed when cumulus clouds break up into several medium-sized clouds and rise to an elevation between 1 and 3 miles. Cumulonimbus clouds are massive towers of cumulus clouds. They range in elevation from just a few feet off the ground to 7 miles high. They bring rain. Aristotle, an ancient Greek philosopher, thought that water, air, fire, and earth were the four basic components of weather. Actually, it is only water and air. Meteorologists are weather forecasters who read the sky using cloud information and computer-aided instruments. Precipitation occurs when a cloud releases any form of water, whether it is rain, sleet, snow, or hail. All precipitation begins with a change in temperature. Clouds move with the wind currents. Clouds are heavy air masses of condensed water molecules. Cloud seeding is a way to fill clouds with chemicals that can help cause precipitation.

Name Before Viewing Activity 3 What's the Truth? Some of the statements below are true and some are false. Prior to watching the program, mark the appropriate box in the Before Viewing column. After viewing the program, mark the appropriate box in the After Viewing column. Before Viewing true/false After Viewing true/false Clouds form in the stratosphere. The thermosphere is extremely warm. Where clouds form, there is moisture in the air. The basic cloud types are cirrus and fluffy. Cumulus and stratus clouds occur at low levels. Aristotle was an early weather theorist. The four components of weather are water, air, fire, and earth. Meteorologists are weather forecasters. Precipitation happens when a cloud releases any form of water. All precipitation begins with a temperature change. Clouds are slow moving and almost weightless. Clouds help us predict weather. Humans can create rain. 10 Clouds Video Quiz Sunburst Visual Media, a division of Global Video, LLC

Name After Viewing Activity 1 Summing Up Read the information below to review cloud formation. Use the graphic organizer at the bottom of the page to place the sequence of events for cloud formation in a correctly completed diagram. HOW CLOUDS ARE FORMED Clouds are masses of water droplets or ice crystals that are suspended in the air. When the droplets or crystals become too heavy to remain suspended, they fall to the Earth. In order for clouds to form, three things are needed. First, the relative humidity must be close to 100 percent. Second, tiny bits of matter, such as dust, must be present. (Water collects or condenses around these particles.) Third, something must happen to cool the air. If all three conditions exist, clouds form. The type of clouds that form depend on how cold the air is and how much water is in the air. + Cloud Formation 16 Clouds Video Quiz Sunburst Visual Media, a division of Global Video, LLC

Name After Viewing Activity 7 Cloud Concern Read the information below about cloud seeding. Then, write your own thoughts in the space provided. Be prepared to prove your opinion and ideas in a class discussion. With dry ice and a plane, you can create a rainstorm. Here's how cloud seeding, or making rain artificially, works: A plane drops crushed dry ice into a cloud; the dry ice attracts water droplets and ice crystals; these crystals get bigger and heavier until they fall to Earth as rain. But not everyone agrees on how useful and fair it is to use this process. Some argue that it only slightly increases the rain that would have fallen anyway and that it can steal rain away from other areas.
