UNIT X 30 | UNIT 1 Instructional Routine: Science p. Txxx Sound The Wind A • Activate prior knowledge Direct students’ attention to the illustration on page 30. Ask: What rises with the warm air? What is it called when air rises? What is formed? What cycle is similar to this? What did we learn about cycles? Make a list of responses on the board. • Use prior knowledge Ask students who have lived in different climate zones about their experience with wind. For example, Chicago is called the Windy City because the wind always seems to blow. In deserts, the wind blows the sand across the dunes. • Preview the text Read the title out loud and have students skim the text for words in bold type. Ask volunteers to describe the image. Remind students to use these text features while they listen to help them understand the text. • Listen for understanding Play the audio once. Ask students to listen the first time for a general understanding. • Listen actively Play the audio a second time, asking students to follow the text closely as they listen. • Compare and contrast two texts Ask groups of students to compare and contrast this reading about the topic of weather with “A Meteorologist Talks About Weather.” They should talk about the title, the format, and the content. Students can represent the information in a Venn diagram. Essential Question: How does wind move? Cite text evidence Ask students to read and discuss the Essential Question in pairs. Remind students to look for evidence in the text to support answers. Elicit and write ideas on the board. ANSWERS Wind can be light and breezy or strong and powerful. EXPLORE AND LEARN DIFFERENTIATED INSTRUCTION Scaffold Have students work in groups. Assign tasks. One student writes the words in bold from the text on cards or strips of paper. The other students copy the definitions of these words from the glossary or an online dictionary. Then students take turns to match a word card to a definition. Amplify Have students brainstorm advantages and disadvantages of wind. Create a T-chart on the board to list the best ideas. land ground temperature: 92°F warm air rises wind air cools off cold air sinks ocean water temperature: 85°F Winds can be light and breezy and cool us down on a hot day. Winds can also be strong and powerful, like they are in hurricanes, tornadoes, and thunderstorms. Winds can help move a sailboat or fly a kite. They can also destroy houses or move large amounts of water to shore. What causes wind? The Sun’s rays heat up the atmosphere, but not evenly. Some parts of the atmosphere get warmer than others. Warmer air expands and rises. Cooler air sinks. Because warmer air expands, it creates a low-pressure area. Cooler air creates a high-pressure area. Cool air moves into the low-pressure area. This creates wind. Have you ever felt a breeze, a soft wind, near the ocean? This happens because the air above the land is warmer than the air above the water. As the warm air from above the land rises, the cooler air from above the water moves to take its place. If you’re on the beach, you can feel the wind coming from the water.
