UNIT X 70 | UNIT 2 Instructional Routine: Science p. Txxx Sound A Natural Wonder A • Activate prior knowledge Draw a Venn diagram on the board. Ask: What are some similarities between natural and human-made wonders? What are some differences between them? Have students draw from the examples that they have studied and add their observations to the board. • Preview the text Read the title aloud and have students skim the text for the words in bold type. Have a dictionary race to see who can find each definition first. Then ask for volunteers to describe the photo. Ask: Is this a natural or human-made wonder? Where is it located? How was it formed? Remind students to use the text features while they listen to help them understand the text. • Listen for understanding Play the audio. Ask students to listen the first time for a general understanding. • Listen actively Play the audio again. Ask students to follow the text closely as they listen. Essential Question: How do some natural rock structures form? 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 their answers. Elicit and write ideas on the board. ANSWERS Sample answer: Natural rock structures form through wind, acid rain, and frost wedging. EXPLORE AND LEARN DIFFERENTIATED INSTRUCTION Scaffold Divide students in two teams. Assign different vocabulary words to each team. Have each team write their vocabulary words on a piece of paper along with the definition of each one, which they look for in a dictionary. Explain to students that they should take turns to read one of their definitions. The other team calls out the vocabulary word. Amplify Have students identify local or other natural formations that they are familiar with. Ask: How did it form? What makes it special? Where is it? If students do not have exact information, they can use sentence frames to present their opinions and ideas. I have seen ____________. It is located _______________. I think it was formed by ______________. A hoodoo is a natural column of rock. The columns are tall and thin. Some are the size of a human, and others are up to 10 stories tall. There are famous hoodoos in Bryce Canyon National Park in Utah. These hoodoos formed over millions of years. Weathering is the process of breaking something into smaller pieces. It causes erosion. Wind erodes the rock. The wind breaks down the rocks and carries the pieces away. Acid rain also wears down the rocks. The biggest factor is frost wedging. In the winter, snow melts, and the water goes into cracks in the rocks. It freezes and expands. It makes the cracks bigger. Large pieces of rock fall off. Through wind, acid rain, and frost wedging, the hoodoos form over time. Hoodoos are also called earth pyramids and tent rocks because of their shapes. A Paiute legend says that long ago a group of people drank all of the water and ate all the food in the area. They were turned into stone as punishment. If you look at the hoodoos today, they look like people! A Natural Wonder A Read the informational text. Hello Hoodoos! How do some natural rock structures form? ?
