Lesson Synopsis

1. Opening

A. Engage the Learner - RI.7.6 (5 minutes)

2. Work Time

A. Launch Anchor Text: Trash Vortex - RI.7.2 (20 minutes)

B. Analyze Author's Purpose - RI.7.6 (15 minutes)

3. Closing and Assessment

A. Compare Purpose in Film and Text - RI.7.6 (5 minutes)

4. Homework

A. Preread Anchor Text: Students finish reading chapter 1 and preread chapter 2 of Trash Vortex in preparation for studying an excerpt from the chapter in the next lesson. Students choose one of the photos or graphics in chapter 2 and explain in a brief paragraph the author's purpose for including it. Students also use context and, if necessary, a dictionary to determine the meaning of unfamiliar vocabulary in chapter 2 of Trash Vortex. Then they record the words and their definitions in the correct section of their vocabulary log.

Opening

A. Engage the Learner - RI.7.6 (5 minutes)

MEETING STUDENTS' NEEDS 

For the entrance ticket in Opening A, encourage students to work independently at first to grapple to answer the questions. Then they can share their responses with a partner to check and expand their work. Grappling first and then working with a partner will increase student engagement, independence, and speaking and listening skills.

For the entrance ticket in Opening A, encourage students to work in pairs to use words from the prompts to create sentence frames for responding to the questions. Consider pairing students by either content or language proficiency. Strategic grouping affords students the opportunity of supporting and being challenged by others.

Work Time

A. Launch Anchor Text: Trash Vortex – RI.7.2 (20 minutes)

“I can determine two or more central ideas and trace their development over the course of Trash Vortex.

“What habits of character did you see in this excerpt? Who demonstrated them? What did they look/sound like?” (Possible response: Charles Moore demonstrates initiative and perseverance as he learns about the plastic problem in the ocean and decides that he must do something about it. He also contributes to a better world by working to improve his surroundings.)

“What is the gist of this excerpt?” (Charles Moore sees lots of plastic in ocean, learns where it comes from.) As necessary, consult the Gists: Trash Vortex (example for teacher reference) document to check students’ responses.

“What are the central ideas in this excerpt?” (There is a large amount of plastic floating in the ocean. Ocean gyres transport plastic and also form the plastic vortexes.) If students have trouble identifying the central ideas, ask: “What big ideas does the author want us to know about plastic in the ocean?”

“What are some of the details the author uses to develop the central ideas in this excerpt?” (The author uses the story of Charles Moore discovering the plastic in the ocean to help describe how much of it there is. Then, the author describes in detail how the gyres form the plastic vortexes.) If students have trouble identifying the details, ask: “What important details, facts, or examples does the author use to tell us that there are large amounts of plastic in the ocean? How does she tell us about the gyres and plastic vortexes?”

MEETING STUDENTS' NEEDS 

For Work Time A and B, students may need more support in addition to the whole-class analysis of the central ideas and author's purpose. Provide additional wait time for students to read, process the questions, and formulate their responses. Students may also need time to orally process their responses with a partner before sharing out.

During Work Time A as time allows, students can continue their work from the Language Dive in Lesson 7 by spending some time identifying different types of sentences in the excerpt from Trash Vortex. They can share these examples with each other and with classmates who need heavier support, identifying the type of sentence and function in the excerpt.

For Work Time A and B, students may need more support in addition to the whole-class analysis of the central ideas and author's purpose. Provide additional wait time for students to read, process the questions, and formulate their responses. Also, record student responses on the board or a displayed version of the note-catcher to support students visually. Before sharing out, students may also need time to orally process their responses with a partner in English or their home language.

B. Analyze Author’s Purpose – RI.7.6 (15 minutes)

“I can determine an author's purpose in Trash Vortex.”

“What is happening in this paragraph? What words and phrases show what is happening? (Charles Moore’s journey is being described. The author uses phrases like “Moore felt the wind . . . die to a whisper” [4] to show what is happening.)

“What purpose does this paragraph serve in the excerpt? How does it add to the text?” (The purpose of this section is to engage the reader and describe the scene when Charles Moore discovers plastic. It adds to the text by creating interest in the story and describing what the ocean looked like, and it introduces Charles Moore.) If students need support determining the purpose, remind them of the four general purposes (to inform, engage, persuade, or entertain) and ask them to consider which of these purposes this section shows.

“What purpose does this paragraph serve in the excerpt?” (The purpose of this section is to explain how a plastic gyre breaks up plastic. The author describes how the gyre pulls the plastic into the center, where it “remains trapped for years” [8]. The author describes how the gyres “slowly shred plastic into bits called microplastics” [8].)

Closing

A. Compare Purpose in Film and Text - RI.7.6 (5 minutes)

"How does the information in this text compare to the documentary A Plastic Ocean? How do the two anchor texts work together to inform each other?" (We learned about the plastic vortexes in A Plastic Ocean, including how a gyre worked. In the video, the filmmakers used graphics to explain gyres. In the text, the author describes how the vortexes were first discovered. Both the text and the video explain how the ocean and vortexes create tiny pieces of plastic and bring them together in the center.)

"What were some of the purposes of the film? How do those purposes compare to the purposes in text Trash Vortex?" (The film's purposes were to inform about plastic pollution statistics and issues, persuade people to act to stop plastic pollution, and to inspire and engage with beautiful images of nature and stories of people helping improve the environment. The text seems to have similar purposes so far, informing about the problem, entertaining/engaging with stories, and possibly persuading to act in other chapters.)

MEETING STUDENTS' NEEDS 

In Closing and Assessment A, allow students to respond to the discussion prompts in the modality that best suits them. They may want to record their responses in writing or practice their oral responses with a partner before sharing them out. Allowing students to respond in multiple ways increases their confidence and success in comparing the film and text.

As in the lighter support, in Closing and Assessment A, allow students to respond to the discussion prompts in the modality that best suits them. In addition to the lighter supports, students who need heavier support may want to share their responses in their home language. Allowing students to respond in multiple ways increases their confidence and success in comparing the film and text.
