Lesson Title

The Body's Response to Stress: Fight-or-Flight and Hormonal Effects

---

Learning Objectives

By the end of this lesson, students will be able to:

• LO1: Explain the physiological fight-or-flight response, including nervous system activation.
• LO2: Describe the roles of cortisol and adrenaline in stress response and their effects on the body.
• LO3: Analyze the short-term and long-term health implications of these hormonal responses.
• LO4: Participate in a hands-on simulation demonstrating these responses.

Standards Alignment

Common Core State Standards (CCSS) Integration

Note: While Health is not directly governed by CCSS, this lesson integrates CCSS-aligned skills in reading, speaking, and writing relevant to Science and technical subjects as per
CCSS.ELA-LITERACY.RST.9-10.3: Follow precisely a complex multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.
CCSS.ELA-LITERACY.RST.9-10.7: Translate quantitative or technical information expressed in words in a text into visual form (e.g. table or chart) and vice versa.
CCSS.ELA-LITERACY.SL.9-10.1: Initiate and participate effectively in a range of collaborative discussions.
CCSS.ELA-LITERACY.WHST.9-10.2: Write informative/explanatory texts, including the narration of historical events, scientific procedures/experiments.

Materials Needed

• Stress Response Handout (simplified for readability and dyslexic-friendly fonts)
• Colored markers and chart paper
• Temporary pulse oximeters or stopwatches for heart rate measurement
• Index cards with "Cortisol" and "Adrenaline" hormone fact cards
• Whiteboard and markers

---

Success Criteria

• Students accurately describe the fight-or-flight response steps.
• Students explain cortisol and adrenaline hormone functions clearly.
• Students complete the hands-on activity following procedure precisely and record observations.
• Students engage thoughtfully in discussion, demonstrating understanding of health implications.

Lesson Breakdown

1. Introduction and Activation (7 minutes)

• Engage: Begin by asking: “What happens to your body when you feel scared or stressed?” Facilitate a quick think-pair-share.
• Use answers to briefly introduce the fight-or-flight response.
• Show a simplified diagram of the nervous system reacting to stress (sympathetic nervous activation).

2. Teaching Input: Hormonal Effects Explained (10 minutes)

• Present a student-friendly explanation of cortisol and adrenaline. Use analogies (“Adrenaline is like your body’s natural energy drink!”).
• Distribute hormone fact cards with simple language and dyslexia-friendly fonts.
• Students pair up and summarize their card to each other (Supporting CCSS.ELA-LITERACY.SL.9-10.1).

3. Hands-On Activity: Simulating Fight-or-Flight Response (15 minutes)

• Step 1: Measure baseline heart rate (resting) using pulse oximeters or manually with stopwatches. Record on chart paper.
• Step 2: Engage students in a brief physical activity (e.g., 1 minute of jumping jacks) to simulate adrenaline release.
• Step 3: Immediately measure and record heart rate again for comparison.
• Step 4: Discuss what their bodies just experienced in terms of fight-or-flight response and hormone effects.
• Students map this on a graphic organizer showing input, hormone release, and output effects (aligns with CCSS.ELA-LITERACY.RST.9-10.7).

4. Discussion: Health Implications (8 minutes)

• Facilitate a class discussion about how these stress responses can be helpful short-term but harmful if chronic.
• Connect to health topics such as anxiety, hypertension, and immunity.
• Encourage students to think critically about managing stress based on biology.

5. Wrap-Up and Reflection (5 minutes)

• Students write a short paragraph summarizing why understanding these responses is important for managing stress (supports CCSS.WHST.9-10.2).
• Invite 2-3 students to share their reflections aloud.

Differentiation Strategies

Learner Need	Strategy
ELLs	Use visuals and simplified language; provide bilingual glossary cards if possible.
Dyslexic learners	Provide dyslexia-friendly summaries and fact cards; allow use of text-to-speech tools.
Advanced learners	Offer an extension task: research how chronic cortisol affects specific organs; prepare a mini-presentation.
Students with attention challenges	Use movement-based activity to engage physically; provide clear step-by-step instructions.

---

Extension Activities (For Advanced Learners)

• Research and prepare a poster on how chronic stress affects mental health or specific diseases.
• Create a short informative video explaining the fight-or-flight response that could teach younger students.

---

Assessment

• Informal assessment through observation of participation in discussion and activity.
• Review of students’ paragraph reflections for comprehension and use of scientific vocabulary.
• Exit ticket: One sentence describing how adrenaline affects the body during stress.

---

Teacher Reflection & Notes

• Monitor for students who may feel overwhelmed during the physical activity; offer alternatives such as simulated stress breathing techniques.
• Reinforce vocabulary regularly and refer to hormone fact cards often.

---

Resources for Dyslexia-Friendly Reading

• Use sans serif fonts like Arial or Comic Sans.
• Texts with increased spacing, short sentences, and bullet points.
• Highlight key terms in color and include icons for visual cues.

This highly interactive and standards-aligned lesson ensures students not only learn important scientific concepts about stress physiology but also practice key literacy skills crucial under Common Core guidance. The hands-on nature and meaningful discussions foster engagement with the biological and health implications of stress management.
