Who this lesson is for?
This lesson is designed for Years 3 and 4 students who are beginning to learn about how bodies change and grow over time. It suits students who are ready for factual, age-appropriate discussion about growth and body changes, without needing to explore puberty in detail.
It is suitable for:
primary wellbeing lessons
Health or PDHPE teaching
pastoral care or advisory sessions on growth and development
introductory lessons on puberty and body changes
respectful relationships programs that include body awareness
Suitability should be based on more than age alone. Teachers should consider the lesson focus, student maturity, cohort needs, classroom culture, existing discussion norms and available support pathways.
Best used when
Use this lesson when students need clear, practical language for recognising unkind behaviour and knowing what to do next.
Introducing body changes and growth Use when students are beginning to learn about puberty and body changes for the first time.
Building a respectful classroom culture Use when reinforcing respect for different rates of growth and development.
Preparing for a health or PDHPE unit Use when introducing a broader unit on growth, development or puberty.
Supporting a whole cohort proactively Use when you want to normalise body changes before students start noticing differences among peers.
Reinforcing help-seeking about growing up Use when students need to know who they can ask questions about their body or growth.
Preparing for transition to upper primary Use when students are moving towards year levels where body changes become more noticeable.
The lesson can be used proactively with the whole class. It does not need to follow a specific incident.
Why this lesson matters
Students benefit from having simple, factual language for talking about body changes before questions or comparisons come up on their own. Without this, students may rely on guesses, rumours or teasing to make sense of the changes they notice in themselves or others. Teaching about body changes early helps normalise growth as something everyone experiences at their own pace. It gives students a shared, respectful vocabulary for talking about growing up, and reduces the chance that differences in development become a source of embarrassment or unkind comments. This lesson supports a classroom culture where body changes are treated as a normal part of life, and where students feel confident asking a trusted adult questions about their own growth and development.

Teaching notes & Delivery Considerations
This lesson includes content about unkind behaviour, exclusion and asking adults for help. It should be taught with calm, clear discussion norms.
Before teaching
Remind students not to name classmates or share personal stories about their own or others' bodies
Frame discussion around general examples rather than personal comparisons
Check students have consistent, factual language for body parts and growth changes appropriate to the year level
Identify trusted adults students can speak to about growing up
During delivery
Use general examples such as growing taller or losing baby teeth rather than focusing on one specific change
Keep language factual and body-respectful, avoiding comparisons between students
Give students time to ask questions without singling anyone out
Reinforce that everyone grows and changes at their own pace
Supporting safe discussion
Use privacy and respectful discussion as classroom norms rather than promising confidentiality
Avoid asking any student to speak on behalf of others' experiences of growing up
Be prepared to follow your school's child safety, wellbeing or child protection procedures if a student discloses harm or says they feel unsafe.
Adaptation options
Use partner or small group discussion for students who are less confident speaking to the whole class
Provide drawing or written reflection as an alternative response option
Spend more time on trusted adults and help-seeking if students need extra support identifying who to ask
