Lesson Plan
Body Changes Blueprint
Students will explore and understand key physical changes during puberty through interactive discussions and a timeline activity, fostering a supportive environment where they feel informed and confident asking questions.
Puberty brings many changes that can cause anxiety or confusion. This lesson equips 5th graders with accurate knowledge, reduces misinformation, and builds a safe classroom community for open dialogue.
Audience

Prep
Lesson Preparation
10 minutes

- Print enough copies of the Life Stage Timeline handout for pairs
- Prepare index cards or printables showing various body changes
- Arrange seating in a circle for the icebreaker and reflection
- Gather chart paper, markers, and sticky notes for group work
Step 1
Change Chat Icebreaker
5 minutes
- Students sit in a circle and share their name and one word that comes to mind when they hear "puberty."
- Pass a soft ball; the catcher states their word and explains why.

Step 2
Introduction & Classroom Norms
5 minutes
- Teacher states the lesson objective and why understanding puberty matters.
- Co-create norms: respect, confidentiality, no teasing, and curiosity.

Step 3
Explore Puberty Unboxed Slide Deck
10 minutes
- Project Puberty Unboxed slides on physical changes in girls and boys.
- After each slide, pause for 1–2 student questions or reflections.
- Use simple, age-appropriate language and clarify any misconceptions.
Step 4
Life Stage Timeline Activity
15 minutes
- Divide students into pairs and give each pair the Life Stage Timeline handout and change cards.
- Pairs sequence the cards chronologically and glue or place them on a shared timeline sheet.
- Circulate to prompt discussion: Why does this change happen? How might it feel?
- Invite one or two pairs to display and explain their timeline.
Step 5
Reflection Circle Cool-Down
10 minutes
- Reconvene in the original circle.
- Each student shares:
- One new fact they learned
- One question they still have (anonymous questions on sticky notes are okay)
- Collect sticky-note questions to address in a follow-up or provide resources.
- Reinforce where students can go for reliable information and support.

Slide Deck
Puberty Unboxed
What’s happening to your body? Let’s explore together!
Welcome students! Introduce today’s topic: understanding the physical changes of puberty in a supportive environment. Mention our color theme (#FFB3C1, #FF99A8, #FF7F8F) to keep slides bright and friendly. Prompt: “What have you heard about puberty?”
Growth Spurt: Reaching New Heights!
• Bones grow longer rapidly
• You may feel taller almost overnight
• Arms, legs, hands, and feet often grow first
Explain that a growth spurt is often the first sign of puberty. Show a simple graphic of a growing child. Ask: “Has anyone felt like they shot up overnight?”
Body Hair: A Natural Cover Up
• Hair appears underarms & in the pubic area
• Boys may see facial hair (upper lip, chin)
• Hair helps protect and regulate temperature
Display images of underarm and facial hair icons. Clarify that hair growth is normal and healthy. Prompt: “How do you feel noticing new hair? Any surprises?”
Skin & Sweat: More than Just a Glow
• Oil glands become more active → oily skin
• Acne or pimples may appear on face, chest, back
• Sweat glands work harder → more sweating
Use before/after skin illustrations. Explain oil gland activity and normal acne. Ask: “What healthy routines can help your skin?”
Voice Changes: Finding Your Sound
• Boys: voice may crack and deepen as the larynx grows
• Girls: minor shifts in pitch or tone can occur
• All: voice changes are a normal part of growing
Show a cartoon of a microphone glitching for voice cracks. Explain voice box growth. Ask: “Has your voice ever cracked unexpectedly?”
Emotions on the Move
• New, stronger emotions—excitement, worry, etc.
• Mood swings can happen quickly
• Talking helps: friends, family, trusted adults
Present emoji faces showing different emotions. Stress that mood swings are common. Prompt: “Who can you talk to when feelings get big?”
Questions & Next Steps
• What surprised you today?
• What questions do you still have?
• Remember: everyone goes through these changes
Invite students to share any questions, either out loud or via sticky notes. Let them know there’s no such thing as a silly question. Remind them of classroom norms.
Warm Up
Change Chat Icebreaker
Time: 5 minutes
Purpose:
Builds community, surfaces initial feelings about puberty, and helps the teacher gauge student anxieties or excitement.
Instructions:
- Arrange students in a circle, either seated on the floor or in chairs.
- Teacher holds a soft ball (or other tossable object) to start.
- The student with the ball says:
- Their name
- One word that comes to mind when they hear “puberty”
- That student then gently tosses the ball to a classmate, who repeats the process.
- Teacher records each word on chart paper where everyone can see.
- After going around once (or after ~10 students), pause to notice common themes and validate all responses.
Example Student Responses:
- “Exciting” – “I’m excited because I might get taller really fast!”
- “Weird” – “It feels weird when my voice cracks out of nowhere.”
- “Nervous” – “I’m nervous about having pimples.”
Debrief (1–2 minutes):
- Read aloud the words students shared.
- Invite volunteers to say why they chose their word, if they’re comfortable.
- Highlight that everyone’s reaction is normal and that sharing helps us support each other.

Activity
Life Stage Timeline Activity
Time: 15 minutes
Purpose:
Help students explore and understand the typical sequence of physical changes during puberty, discuss why they occur, and reflect on how these changes might feel.
Materials:
- Sets of body-change cards (each card names a change and includes a simple illustration)
- Blank timeline worksheet (one per pair)
- Glue sticks or tape
- Markers
Setup (before class):
- Print and cut out the body-change cards.
- Prepare a blank timeline worksheet for each pair.
- Organize cards into envelope sets for easy distribution.
Instructions:
- Pair Up & Distribute (2 min):
- Have students find a partner and sit together.
- Give each pair one envelope of body-change cards and one timeline worksheet.
- Sequence the Changes (8 min):
- In pairs, sort the cards in the order these changes typically occur during puberty.
- Once agreed, glue or tape each card onto the timeline worksheet in its proper spot.
- Teacher Tip: Circulate and ask, “Why does this change happen?” and “How might it feel?” to deepen discussion.
- Gallery Share (5 min):
- Invite 1–2 pairs to place their timeline sheets on the board or wall.
- Each pair briefly explains:
- One change they placed early in the timeline and why
- One change they placed later and how it might feel
Reflection Prompts:
- Why is it useful to see these changes in order?
- How might each person’s timeline differ? What factors influence this?
- What can you do to take care of your body during these changes?
Cool Down
Reflection Circle Cool-Down
Time: 10 minutes
Purpose: Consolidate learning, surface remaining questions, and reinforce a supportive classroom community.
Materials: Sticky notes, pens/markers, chart paper (to collect sticky notes), Reflection Circle norms displayed
Instructions
-
Form the Circle (1 min)
- Have students return to their original circle seating.
- Remind them of our classroom norms: respect, confidentiality, and curiosity.
-
Silent Reflection & Writing (4 min)
- Distribute 2 sticky notes to each student.
- Prompt A: Write one new fact you learned today about puberty and body changes.
- Prompt B: Write one question you still have.
- Encourage neat writing so the class can read everyone’s notes.
-
Share & Collect (3 min)
- Invite volunteers (up to 3) to read aloud one of their notes—either a fact or a question.
- After sharing, students stick all their notes on the chart paper in the center.
-
Teacher Wrap-Up (2 min)
- Quickly scan the notes and highlight any common themes (e.g., questions about acne, growth spurts, mood changes).
- Let students know you will address these questions in a follow-up, provide resources, or meet one-on-one as needed.
- Reinforce where they can go for reliable information (school nurse, parent, trusted adult).
End of Lesson: Thank students for their honesty and curiosity. Remind them that everyone’s body changes at their own pace and that the classroom remains a safe place to ask questions.
