Best used when
Use this lesson when students need clear, practical language for recognising unkind behaviour and knowing what to do next.
Introducing sexual health education Use when pupils are beginning structured learning about STI and pregnancy prevention.
Building on consent learning Use when pupils have already covered consent and boundaries and are ready to apply this to sexual health.
Delivering a structured RSE unit Use as part of a planned relationships and sex education sequence across the term or year.
Supporting pupils' questions about sexual health Use when pupils need accurate, age appropriate answers to common questions in a calm setting.
Preparing for key stage transitions Use when pupils are moving into new year groups and need refreshed, age appropriate information.
Reinforcing respectful relationship skills Use when revisiting communication, boundaries and mutual respect within relationships.
The lesson can be used proactively with the whole class. It does not need to follow a specific incident.
Why this lesson matters
Pupils benefit from clear, accurate information about sexual health well before they need to rely on it. Understanding how STIs and unwanted pregnancies can be avoided gives pupils practical knowledge they can use to make safer, more informed choices. This topic is not only about physical health. Consent, communication and respect for boundaries all shape whether a relationship feels safe, and pupils benefit from language that helps them recognise pressure or risk early. The lesson supports a classroom culture where questions about sexual health can be asked openly and without embarrassment. Pupils learn that seeking accurate information and support is a normal, responsible part of staying safe.

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 pupils not to share personal experiences or name classmates during discussion
Frame the lesson around general scenarios rather than real situations pupils have experienced
Identify trusted adults, the school nurse or health services pupils can approach with questions
Be prepared to follow your school's safeguarding procedures and speak with the designated safeguarding lead if a pupil discloses harm or says they feel unsafe
During delivery
Keep language age appropriate and avoid graphic detail
Use general examples and scenarios rather than personal disclosures
Give pupils opportunities to ask questions without pressure to share personal experiences
Reinforce that consent and respect apply in every relationship discussed
Supporting safe discussion
Use privacy as the guiding principle rather than promising confidentiality
Redirect any personal disclosures to a private conversation after the lesson
Signpost trusted adults, pastoral staff or health services for pupils who want to talk further
Adaptation options
Adjust depth of discussion based on pupils' prior RSE learning
Use whole class or small group discussion depending on cohort readiness
Allow extra time on consent and communication if pupils need more foundational support
