Unit Context

Unit: Mastering Stress Management
Lesson: 3 of 5
Title: The Physiology of Stress: Hormones and Responses

---

Learning Objectives

Students will be able to:

1. Describe the physiological fight-or-flight response triggered by stress (CCSS.ELA-LITERACY.RST.9-10.3).
2. Explain the roles of adrenaline and cortisol hormones in stress responses (CCSS.ELA-LITERACY.RST.9-10.7).
3. Analyze how these hormones affect physical and emotional health (CCSS.ELA-LITERACY.WHST.9-10.9).
4. Demonstrate understanding through a hands-on simulation activity.

Common Core Alignment

• 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 into visual form (e.g., a table or chart) and vice versa.
• CCSS.ELA-LITERACY.WHST.9-10.9: Draw evidence from informational texts to support analysis, reflection, and research.

Materials Needed

• Printed hormone fact sheets (dyslexia-friendly font: OpenDyslexic, larger font size)
• Colored wristbands or sticky notes in two colors (red for adrenaline, blue for cortisol)
• Whiteboard and markers
• Stress physiology diagram (with clear visuals, minimal text)
• Quiz handout (short formative assessment)
• Timer

---

Success Criteria

• Correctly identify and describe adrenaline and cortisol functions.
• Accurately explain the fight-or-flight physiological responses.
• Actively participate in the hormone simulation activity.
• Complete the quiz demonstrating comprehension above 80%.

Lesson Procedure

1. Introduction (5 minutes)

• Greet students and briefly review previous lessons on emotional and cognitive stress.
• Pose a compelling question: "What happens inside your body when you feel scared or stressed?"
• Write keywords on the board: fight-or-flight, adrenaline, cortisol.
• Provide dyslexia-friendly hormone fact sheets; allow a moment for silent reading.

2. Direct Instruction (10 minutes)

• Use the stress physiology diagram to explain:
  • The fight-or-flight response (activation of autonomic nervous system).
  • Roles of adrenaline (increases heart rate, energy) and cortisol (regulates longer term stress responses).
• Emphasize real-world relevance: physical symptoms (racing heartbeat), emotional effects (anxiety).
• Incorporate simple Q&A to check understanding.

3. Hands-On Activity: Hormone Simulation (15 minutes)

• Divide students into groups of six (5 groups total). Each group receives red and blue wristbands.
• Assign roles representing body parts: heart, lungs, brain, muscles, and adrenal glands (students wear wristbands representing hormone release).
• Simulation steps:
  • At signal, “adrenal glands” release adrenaline (red wristbands) to heart and muscles, students act out increased heart rate and energy (jumping lightly or fast clapping).
  • Then, “release” cortisol (blue wristbands) affecting brain and lungs, students demonstrate deep breathing and slower movements showing regulation after stress spike.
• Debrief: Discuss how this shows the body’s hormone interaction during stress.

4. Group Discussion (8 minutes)

• Guided discussion on physical feelings during the simulation.
• Discuss short-term vs long-term effects of stress hormones.
• Explore coping techniques briefly in context of hormone moderation (to be expanded in upcoming lessons).

5. Formative Assessment & Wrap-Up (7 minutes)

• Distribute a brief quiz (multiple choice and short answer) focused on hormone functions and fight-or-flight concepts.
• Collect quizzes for quick review.
• Summarize key points verbally and refer back to the success criteria.

Differentiation Strategies

• For diverse learners:

  • Provide hormone fact sheets in dyslexia-friendly fonts and high-contrast paper.
  • Use visual aids with minimal text and clear icons.
  • Allow oral responses and peer support during discussions.

• For students with IEPs:

  • Offer additional time for activities.
  • Provide an outline or graphic organizer beforehand.

• For ELL students:

  • Simplify language in materials.
  • Use gestures and visuals extensively.
  • Pair with bilingual peer if available.

---

Extension Activities (For Advanced Learners)

• Research and present how chronic cortisol exposure impacts health conditions such as hypertension, diabetes, or depression.
• Design a mini-experiment to measure heart rate changes before and after a mild stressor (e.g., quick math problems) and graph the results.
• Write a brief reflective essay linking physiological stress responses to mental health and lifestyle choices.

---

Teacher Notes

• Keep energy high during simulation to maintain engagement.
• Frequently check for understanding with quick thumbs up/down signals.
• Emphasize the integration of physiology with emotional health to build comprehensive stress management skills.

With this lesson, students will gain a foundational understanding of how the body responds to stress physiologically and how hormones like adrenaline and cortisol influence both immediate responses and longer-term health. The hands-on activity ensures a kinesthetic learning experience that promotes retention and engagement.
