Lesson Plan

Brain Basics Plan

Students will identify key brain structures and understand the stages of adolescent brain development, using diagrams and guided discussion to connect anatomy with real-life behavior changes.

Grasping how the adolescent brain grows and adapts empowers students to better understand their own behavior and supports healthier decision-making.

Audience

10th Grade

Time

30 minutes

Approach

Interactive diagrams, discussion, hands-on labeling

Prep

Teacher Preparation

10 minutes

Step 1

Introduction & Diagram Overview

5 minutes

  • Display the Brain Anatomy Diagram
  • Briefly review each major structure (e.g., prefrontal cortex, amygdala, hippocampus)
  • Ask students to share one behavior they think each part controls

Step 2

Class Discussion

10 minutes

  • Project the Adolescent Development Infographic
  • In pairs, students identify two brain changes during adolescence and predict behavioral impacts
  • Select pairs to share insights with the class

Step 3

Labeling Activity

10 minutes

Step 4

Cool Down Reflection

5 minutes

  • Ask students to write one thing they learned about their own brain development
  • Collect reflections or have volunteers share brief takeaways

Discussion

Brain Chat: Real-Life Brain in Action

Discussion Objectives

Guidelines

  • Listen respectfully and wait your turn to speak.
  • Build on your classmates’ ideas.
  • Support your points with evidence from our materials.
  • Keep contributions concise and focused.

Warm-Up (5 minutes)

Quickly share one situation this week where you felt impulsive or overly emotional. What happened?



Core Prompts (20 minutes)

1. Risk and Reward

Scenario: Imagine you’re hanging out with friends and someone suggests a challenge that feels risky (skipping class, trying something daring).

  • Which brain areas (e.g., prefrontal cortex, amygdala) are most active when you evaluate risk versus reward?
  • How does the balance between these areas change during adolescence?
    Follow-up: What strategies could help you make a safer choice next time?






2. Emotions Under Pressure

Scenario: You get into an argument over text and feel your heart racing.

  • Which structure is triggering that “fight-or-flight” response?
  • How might an underdeveloped prefrontal cortex affect how you respond?
    Follow-up: Name one technique (e.g., deep breathing, pausing) to help manage immediate emotions.






3. Memory and Learning

Scenario: You notice you remember stuff better when you study with music or by quizzing a friend.

  • How does the hippocampus help form and retrieve memories?
  • What adolescent-development changes can strengthen study habits?
    Follow-up: Share one new strategy to boost your learning based on this discussion.






Reflection & Closing (5 minutes)

Write one key insight you gained today about your own brain development and how you’ll apply it in the next week.

Activity

NeuroJourney: Mapping Brain Development Milestones

Activity Objectives

  • Engage students in a kinesthetic, collaborative mapping game to sequence key milestones in adolescent brain development.
  • Reinforce understanding of how structural changes unfold over time and influence behavior.

Why This Matters

By physically moving through development “stations” and placing milestones on a shared timeline, learners will internalize the sequence and significance of brain changes—helping them connect anatomy with real-life growth and choices.

Materials

Teacher Prep (10 minutes)

Instructions

  1. Introduction & Group Formation (5 minutes)
  • Briefly remind students of major brain structures (prefrontal cortex, amygdala, hippocampus).
  • Explain that they will travel through stations, each representing an age range, and map developmental milestones.
  1. Station Rotations (15 minutes)
  • Groups start at a station and draw one Timeline Card from the deck.
  • Read the milestone, discuss how the change impacts behavior or learning, then tape the card in the correct spot on their Mapping Sheet.
  • Rotate clockwise every 3–4 minutes until all cards are placed.



  1. Timeline Compilation (5 minutes)
  • Once all stations are complete, groups walk to a central display area and combine their Mapping Sheets into a master timeline.
  • Label connections between milestones (e.g., increased prefrontal connectivity leads to better impulse control).



  1. Gallery Walk & Reflection (5 minutes)
  • Students tour other groups’ timelines, adding one sticky-note question or insight to each display.
  • Return to their own timeline and discuss one new idea they observed.

Cool Down & Debrief

  • Ask each student to write on chart paper one personal takeaway: How will knowing this developmental sequence help them make choices or study better?
  • Share aloud or post on a class “Brain Growth Wall.”

Worksheet

Brain Structure and Development Worksheet

Part A: Label the Diagram

Using the Brain Anatomy Diagram, label the following four major structures by writing their names next to each blank below:








Part B: Structure Functions

  1. Prefrontal Cortex: Describe one key function of the prefrontal cortex and explain why its development is especially important during adolescence.






  2. Amygdala: Explain the role of the amygdala in emotional responses and discuss how heightened amygdala activity might influence teenage behavior.






  3. Hippocampus: What role does the hippocampus play in memory formation and recall? Describe one way you can use this information to improve your study habits.






Part C: Reflection

Think of a recent situation when you made an impulsive decision or had a strong emotional reaction.

  • Identify which brain structure(s) were most involved.
  • Suggest one strategy, based on what you learned today, that could help you respond differently next time.

Cool Down

Brain Snap: Quick Exit Ticket

1. Key Insight: What is one important thing you learned today about your brain’s development or behavior?







2. Remaining Question: What question do you still have about adolescent brain growth or how it affects you?







3. Takeaway Action: How will you apply what you learned today to make a healthier choice or study more effectively this week?
