The Changing Adolescent Body & The Menstrual Cycle wellbeing lesson plan
A secondary wellbeing lesson for Years 7 to 8 that helps Australian teachers introduce puberty and the menstrual cycle through a structured, ready-to-teach lesson. Teachers can use the lesson to explain how the body changes during puberty and how the menstrual cycle works, using factual, age-appropriate language. Students learn to recognise the physical and emotional changes that happen during puberty, understand the basics of the menstrual cycle, and connect these changes to everyday healthy habits such as sleep, nutrition and hygiene.

Who this lesson is for?
This lesson is designed for Years 7 to 8 students who are beginning or continuing to experience puberty and may have varying levels of prior knowledge about body changes and the menstrual cycle.
It is suitable for:
secondary Health or PDHPE classes
wellbeing and pastoral care programs
advisory sessions covering growth and development
respectful relationships education units
healthy lifestyles or personal development programs
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 puberty education Use when students are beginning a growth and development unit and need shared, accurate language for body changes.
Teaching the menstrual cycle for the first time Use when students need a factual, calm explanation of what the menstrual cycle is and why it happens.
Reinforcing healthy lifestyle habits Use when connecting puberty to everyday habits such as sleep, nutrition, movement and hygiene.
Building respectful classroom language Use when students need practice discussing body changes without comparison or judgement.
Supporting a Health or PDHPE sequence Use as part of a broader growth, development or healthy lifestyles topic.
Preparing students for ongoing body changes Use when students are likely to keep experiencing puberty-related changes and benefit from a shared understanding in advance.
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 clear, factual information about puberty and the menstrual cycle well before or alongside the changes they experience. Without this, gaps in understanding can lead to confusion, unnecessary worry or unkind comments about bodies that are simply developing at their own pace. Teaching this topic proactively helps normalise a wide range of developmental timelines and gives students a shared, respectful vocabulary for talking about their bodies. It also connects body changes to practical, everyday habits that support wellbeing during this stage of growth. This lesson supports a classroom culture where body changes are discussed calmly and factually, and where students know that questions about puberty and healthy habits are welcome rather than awkward.

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 share personal experiences or comment on classmates' bodies
Frame discussion around general information rather than individual disclosures
Make clear there is no single normal timeline for puberty
Be prepared to follow your school's child safety, wellbeing or child protection procedures if a student discloses harm or says they feel unsafe
During delivery
Use factual, body-respectful language throughout
Avoid framing any single pathway of development as the standard
Give students time to ask questions or reflect privately if preferred
Keep the focus on shared understanding rather than personal comparison
Supporting safe discussion
Encourage privacy and discourage naming classmates or sharing others' stories
Use general examples and scenarios rather than personal disclosures
Remind students they can ask questions after the lesson if they prefer not to ask in front of the class
Adaptation options
Allow written or private reflection for students who are less comfortable speaking aloud
Adjust pacing depending on students' existing knowledge of puberty and the menstrual cycle
Offer follow-up conversations with a trusted staff member for students with further questions
