  Write arguments to support claims with clear reasons and relevant evidence.
• CCSS.ELA-LITERACY.W.11-12.1.A
  Introduce precise, knowledgeable claim(s), establish the significance of the claim(s), distinguish the claim(s) from alternate or opposing claims, and create an organization that logically sequences the claim(s), counterclaims, reasons, and evidence.
• CCSS.ELA-LITERACY.RI.11-12.1
  Cite strong and thorough textual evidence to support analysis of what the text says explicitly as well as inferences drawn from the text (e.g., analyzing the Henrietta Lacks case).
• CCSS.ELA-LITERACY.L.11-12.1
  Demonstrate command of the conventions of standard English grammar and usage when writing.

I Can Statements

• I can identify the components of a strong thesis statement.
• I can examine examples of effective thesis statements related to persuasive ethics.
• I can write my own clear and compelling thesis statement that reflects my stance on an ethical issue.
• I can explain how my thesis statement guides the direction of my persuasive essay.

---

Success Criteria

• Thesis statements clearly express a specific and debatable claim.
• Thesis statements reflect an ethical stance relevant to the Henrietta Lacks case.
• Thesis statements are concise, arguable, and direct.
• Students provide evidence of revision based on peer and teacher feedback.

---

Materials Needed

• Copies of short excerpts from articles about the Henrietta Lacks case (dyslexia-friendly font, e.g., OpenDyslexic).
• Sample thesis statements (both strong and weak examples) printed on paper or displayed digitally.
• Writing notebooks or laptops/tablets.
• Whiteboard and markers.
• Thesis Statement Checklist handout.

Lesson Breakdown

1. Engage: Hook and Prior Knowledge (7 minutes)

• Begin with a brief class discussion: Ask students what they remember about Henrietta Lacks and ethical issues raised in science and medicine (from Lesson 1).
• Show 2-3 thesis statements (some weak, some strong) about ethical questions in the Henrietta Lacks case on the board.
• Ask: “What makes the strong thesis statements better than the weak ones?”
• Write student responses on the board.

---

2. Explicit Teaching: Thesis Components (10 minutes)

• Define a thesis statement: “A sentence or two that clearly states the main argument or claim of your essay.”
• Break down elements of a strong thesis: clarity, specificity, arguability, and connection to ethical issues.
• Use examples related to Henrietta Lacks, highlight these elements verbally and visually.
• Distribute the Thesis Statement Checklist handout, explaining each point.

---

3. Guided Practice: Thesis Analysis (15 minutes)

• In pairs, students receive three thesis statements about Henrietta Lacks ethics issues (ensure one is weak, one moderate, one strong).
• Pairs use the checklist to analyze each thesis, noting strengths and weaknesses.
• Pairs rank the thesis statements from strongest to weakest and prepare to explain their reasoning to the class.
• Teacher circulates, engages students with probing questions to deepen analysis.

---

4. Independent Practice: Writing a Thesis (20 minutes)

• Prompt: “Write a clear, compelling thesis statement on an ethical issue from the Henrietta Lacks case that you feel passionate about.”
• Encourage students to use their notes, checklist, and class discussion insights.
• Provide scaffolding for diverse learners: sentence frames (e.g., “Although some argue ____, I believe ____ because ____.”) and dyslexia-friendly font templates.
• Allow drafting and one peer feedback round in small groups, focusing on clarity and argumentative strength.

---

5. Closure and Reflection (8 minutes)

• Invite 3-4 volunteers to share their thesis statements; provide constructive feedback focusing on checklist criteria.
• Reflect verbally: “How does a strong thesis help you organize your ethical argument in your essay?”
• Exit Ticket: Write one “I can” statement about thesis statements and one question they still have.

---

Differentiation Strategies

• For students with dyslexia: Provide reading materials in OpenDyslexic font, audio versions of the Henrietta Lacks excerpts, and use color-coded thesis statement components.
• For English Language Learners: Use sentence starters and visuals to explain thesis structure; allow extra time.
• For students with IEPs: Pair with a peer mentor; provide guided notes.

---

Extension Activities

• Advanced learners write a thesis statement incorporating counterclaims and a nuanced ethical perspective regarding Henrietta Lacks.
• Research and compare thesis statements from other ethical case studies for added analysis.
• Create an annotated portfolio of multiple thesis drafts showing their writing process and improvements over time.

---

Teacher Reflection Notes

• Assess if students grasp the role of the thesis in guiding an ethical argument.
• Note student engagement and adaptability to peer collaboration.
• Plan targeted mini-conferences with students who need additional support in thesis clarity or argument development ahead of Lesson 3 (Persuasive Essay Outline).
