Lesson Plan

Sleep Science Lesson Plan

Students will understand the science of sleep, identify optimal sleep durations for their age, and design personalized bedtime routines to improve their health and academic performance.

Adequate sleep supports memory, mood, growth, and overall well-being. This lesson equips 6th graders with knowledge and real-life strategies to develop healthy sleep habits and boost classroom success.

Audience

6th Grade

Time

40 minutes

Approach

Interactive slides, guided discussion, hands-on tracking, and peer sharing.

Prep

Prepare Materials

10 minutes

Step 1

Warm-Up

5 minutes

  • Ask students to raise hands if they felt well-rested today and share one word describing how they feel when they sleep well.
  • Record responses on the board to build interest in the topic.

Step 2

Slide Presentation

10 minutes

  • Project Dreamy Data Slides showing brain activity during sleep and recommended hours by age.
  • Briefly explain the science behind REM and deep sleep stages.
  • Highlight consequences of too little or too much sleep on health and learning.

Step 3

Guided Discussion

10 minutes

  • Divide students into small groups and provide prompts from Why Sleep Matters Discussion.
  • Have each group discuss questions like “What factors affect your sleep?” and “How does sleep impact your schoolwork?”
  • Invite one representative per group to share key insights with the class.

Step 4

Sleep Tracking Activity

10 minutes

  • Distribute the Sleep Log Tracker.
  • Model how to log bedtime, wake time, and sleep quality for one week.
  • Ask students to brainstorm two habits that could improve their sleep (e.g., no screens before bed, consistent bedtime).
  • Students begin filling out their own tracker for the upcoming nights.

Step 5

Cool-Down & Share

5 minutes

  • Invite each student to share one new sleep tip they’ll try this week using Share One Sleep Tip.
  • Collect tips on the board to create a classroom “Sleep Success” list.
  • Encourage students to refer to this list when planning their routines.

Slide Deck

Dreamy Data: The Science of Sleep

• What is sleep?
• Why study sleep?
• Quick look at brain and body processes during sleep

Welcome the students and introduce the topic. Explain that over the next few slides we’ll explore what happens in our brains and bodies during sleep, how much sleep we need, and why it matters for our health and school success.

Sleep Stages

  1. Light Sleep (Stage 1 & 2)
    – Easy to wake up
  2. Deep Sleep (Stage 3)
    – Body repair and growth hormones
  3. REM Sleep
    – Dreaming and memory consolidation

Describe the three main sleep stages. Use simple analogies (light sleep = dozing off, deep sleep = recharging, REM = dream time). Emphasize that we cycle through these stages multiple times each night.

Recommended Sleep Hours by Age

Age Group • Recommended Hours
Preschool (3–5) • 10–13 hours
School Age (6–12) • 9–12 hours
Teens (13–18) • 8–10 hours
You (11–12) • Aim for 9–12 hours each night

Point out the recommended sleep hours by age group. Highlight the 9–12 hours recommendation for 11–12-year-olds (6th graders).

Brain Benefits During Sleep

• Memory consolidation (learning & homework)
• Clears waste from brain cells (detox)
• Releases growth hormones (body & brain development)

Explain brain activity benefits. Use bullet points to keep it clear and engaging. Relate memory consolidation to studying and learning.

Consequences of Poor Sleep

Too Little Sleep:
• Difficulty concentrating
• Mood swings & irritability
• Weaker immune system

Too Much Sleep:
• Grogginess & headaches
• Disrupted daily routine

Discuss what happens when we don’t get enough or get too much sleep. Encourage students to relate to times they felt tired or sluggish.

Key Takeaways

• We cycle through light, deep, & REM sleep nightly.
• 6th graders need about 9–12 hours per night.
• Good sleep boosts memory, mood, and growth.
• Next: Let’s discuss why sleep matters and how to improve it!

Summarize key points and transition to the guided discussion. Invite students to think about their own sleep habits and questions.

Discussion

Why Sleep Matters Discussion

Purpose: Connect sleep science to real-life habits and brainstorm strategies for better rest.

Time: 10 minutes

Grouping: Small groups of 3–4 students

Guidelines:

  • Listen respectfully: one speaker at a time
  • Build on classmates’ ideas with questions and examples
  • Stay on topic and keep comments concise
  • Choose one reporter per group to share insights

Discussion Questions

  1. What factors affect how well you sleep at night?
    • Consider routines, environment (light/noise), emotions, and screen time.
    • Follow-Up: How might each factor help or hinder your sleep?


  2. How does the amount of sleep you get impact your mood and energy at school?
    • Share a time you felt extra tired or extra energetic. What happened that day?
    • Follow-Up: How did it affect your focus, participation, or friendships?


  3. In what ways does sleep help your brain learn and remember new information?
    • Relate to a homework assignment, quiz, or project you completed after a good night’s sleep.
    • Follow-Up: What differences did you notice in your memory or grades?


  4. What bedtime habits could you change to improve your sleep this week?
    • Brainstorm at least two specific habits to start or stop (e.g., no screens 30 minutes before bed, set a consistent bedtime).
    • Follow-Up: Why would these changes make a difference?

After Discussion:

  • Each group reporter shares one key insight per question with the class.
  • Teacher records top ideas on the board to reference during the Sleep Tracking Activity.
