Curriculum Alignment

Ontario Health and Physical Education Curriculum, Grade 7, 2019
Strand: Growth and Development and Human Reproduction
Overall Expectation:

B1. Understanding of the reproductive system and human growth
Specific Expectations:
B1.1 describe the changes that occur during puberty and identify the reproductive organs of males and females
B1.2 describe the processes involved in sexual reproduction and explain the role of the reproductive system
B2.1 demonstrate an understanding of the importance of respecting boundaries and consent in personal relationships (contextual tie-in)

Learning Goals

By the end of the lesson, students will be able to:

Identify and describe the major male and female reproductive organs with age-appropriate terminology
Explain the basic biological process of sexual reproduction, including fertilization and development of a zygote
Understand the importance of respecting bodily autonomy and boundaries in relation to their bodies and others

Materials Needed

Anatomical diagram posters (male and female reproductive systems) with clear labels
Handouts: blank diagrams for labelling activity
Colouring pens/pencils
Interactive whiteboard or projector
Pre-prepared simple vocabulary glossary sheet (reproduction, fertilization, uterus, sperm, egg, etc.)
Index cards with key terms and definitions for group activity
“Respect and Consent” prompt cards for discussion

Lesson Outline

1. Introduction (5 minutes)

Hook: Begin by asking, “What do you already know about how babies are made and how our bodies change in puberty?”
Briefly share that today’s focus will be on understanding the reproductive systems in a biological, respectful way to help us learn about human growth and reproduction.
Set classroom norms emphasising respect, privacy, and asking questions politely.

2. Direct Instruction (10 minutes)

Present clear, age-appropriate diagrams of male and female reproductive systems on the board.
Highlight and name the main parts: for males (testes, penis, sperm ducts, prostate), for females (ovaries, fallopian tubes, uterus, vagina).
Using the vocabulary glossary, explain terms like fertilization: when a sperm cell joins with an egg cell to begin a baby’s development.
Use simple animations or drawings projected showing fertilization and early development of an embryo (focus on process, avoid graphic content).

3. Interactive Activity – Label and Colour (15 minutes)

Hand out blank diagrams of male and female reproductive systems to each student.
Give students coloured pencils and have them label each part using vocabulary from the glossary sheet.
Circulate to assist and provide additional explanations as needed.
Once labelled, ask students to colour-code related parts (e.g., organs related to sperm production in blue, egg production in pink).
Discuss as a group after completion.

4. Group Discussion: Respecting Boundaries (10 minutes)

Divide class into 5 groups of 5 students.
Provide “Respect and Consent” prompt cards with scenarios such as “Your friend doesn’t want to talk about their body” or “You want to ask a friend a question about puberty.”
Groups discuss what respectful behaviours look like in each scenario.
Each group shares their biggest takeaway with the class.
Teacher emphasises that knowing about reproductive systems includes respecting privacy and boundaries.

5. Conclusion and Assessment (5 minutes)

Quick oral quiz: Teacher names a body part or process; students raise hand and say what it is or its function.
Exit Ticket: Each student writes down one new thing they learned today and one question they still have (anonymous option).
Collect exit tickets for teacher review to tailor future lessons or offer support.

Differentiation

Provide labelled diagram printouts for students who need extra support.
Offering vocabulary sheets with pictures for ELL or students with learning challenges.
Challenge advanced students to explain the function of each part or how fertilization leads to pregnancy in their own words.

Connections to Other Subjects

Science: Human biology and reproduction basics
Social Studies: Discussion about respect and personal boundaries
Language: New vocabulary acquisition and respectful communication skills

Teacher’s Reflection Prompts

Did students engage with the labelling and colouring activity?
Were there questions indicating confusion or misconceptions about reproduction?
How did students respond to the respect and consent discussion?
What follow-up lessons to plan for understanding puberty changes and relationships?

Notes

Ensure use of medically accurate, age-appropriate vocabulary; avoid slang or euphemisms.
Maintain sensitivity to diverse family structures and cultural backgrounds during discussions.
Reinforce the importance of confidentiality and safe space for student questions.
