UNIT X 266 | UNIT 7 DIFFERENTIATED INSTRUCTION Scaffold Students may find it challenging to understand a long article. It can be helpful to do a think-aloud. Write these questions on the board: What do I know about this topic? What do I think I will learn about this topic? Do I understand what I just read? Where can I get answers to my questions? Read the first sentence of the first paragraph aloud. Say: This sentence tells us that rain forests are important. I think we might learn why they’re important. Then read the second sentence. Say: I understand what tall trees are. But I don’t know what a kapok tree looks like. Continue with the rest of the paragraph. Then have students do a think-aloud for the remaining paragraphs with a partner, using the questions on the board as a guide. Amplify After students read the article, have them work with a partner to create a one-sentence summary of each paragraph. Grammar in Action A • Use text features to predict Have students preview the text, focusing on the title and the photo. Ask: What do you see in the photo? What do you think the threat is? • Listen for understanding Play the audio, directing students to listen for general understanding. Play it again, asking students to read silently and pay attention to the words in bold type. • Guess meaning from context Have students discuss the meaning of the words in bold in small groups. Ask them to read the text around the words (context) carefully to guess the meaning. Go over definitions as a class. • Read closely Direct students to read the text closely without listening to the audio. Have them underline any words or phrases that they don’t understand. Elicit and explain any unfamiliar terms. B Use the vocabulary Reiterate that students may be able to find the meaning of the words in bold from the context of the reading. Have students answer the questions in pairs. Then review answers as a class. ANSWERS 1. Tall trees shelter plants and animals in the rain forest. 2. Two threats to rain forests are logging and ranchers raising cattle. 3. Deforestation is cutting down trees to make room for other things, such as crops. The consequences are less rain, less clean water, more wildfires, loss of medicine, loss of species, and climate change. 4. Sample answer: I think people want to save the biodiversity of the rain forest because some species of plants or animals might help us cure diseases. If they disappear, scientists will never know. EXPLORE AND LEARN PRACTICE Grammar in Action A Read the informational text. Rain forests are one of Earth’s most important biomes. They are home to some of the world’s tallest trees, such as the kapok tree. The trees form a kind of roof that shelters plants and animals. The trees also produce oxygen. Unfortunately, rain forests are one of the most threatened biomes on Earth. The biggest threat to rain forests is logging. Loggers cut down trees for homes, furniture, and cardboard. Most logging companies do not plant trees to replace the ones they cut down. Another threat comes from ranchers and farmers. To meet the demand for less expensive meat, ranchers need more pasture for their cattle. Ranchers cut down trees in the Amazon, the world’s largest rain forest, to make more room for cattle. Farmers cut down trees to grow more crops. These actions have serious consequences. Deforestation can lead to less rain, less clean water, and a greater threat of climate change. Climate change increases wildfires in rain forests. Wildfires are a threat to animals and plants, which the world could lose. For example, nearly one-fourth of today’s medicines comes from plants that grow only in the rain forest. Rain forest ecosystems have the greatest biodiversity on the planet. Millions of species live in rain forests. Less than one percent of them have been studied. These species could disappear before scientists have an opportunity to study them. There are groups around the world trying to save the rain forests. to the World’s RAIN FORESTS B Use the vocabulary 1. What shelters plants and animals in the rain forest? 2. What are two threats to rain forests? 3. What is deforestation? What are the consequences? 4. Why do you think people want to save the biodiversity of the rain forest?
