Lesson Duration: 45 minutes
Week & Period: Week 23, Period 4
Topic: Male and Female External Reproductive System & Adolescent Development
Sub-topic: Structures and functions, puberty, menstruation, ovulation, teenage pregnancy, reproductive health

Learning Objectives
By the end of the lesson, students should be able to identify male and female reproductive structures, describe changes at puberty, and understand menstruation, ovulation, and reproductive health

Previous Knowledge
Students already know basic human anatomy and puberty changes

Instructional Materials
Diagrams of male and female reproductive systems, charts on puberty, handouts, models

Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Learners’ Activities (Expanded): Students discuss body changes they have noticed in themselves or peers
Assessment Checks: Teacher asks for examples of puberty changes
Notes (Expanded & Detailed): Ensure discussions are age-appropriate and sensitive

B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Learners’ Activities (Expanded): Teacher introduces male and female external reproductive structures using diagrams, models, or illustrations, highlighting each part’s name and function (e.g., penis, scrotum, testes, vulva, labia, clitoris). Teacher explains puberty changes in boys and girls, including physical changes (growth of body hair, voice changes, breast development), emotional changes (mood swings, self-awareness), and social adjustments (changing responsibilities, expectations). Teacher details menstruation and ovulation, explaining the menstrual cycle and fertile periods. Teenage pregnancy is discussed, including risks, consequences, and prevention strategies. Learners label reproductive system diagrams and participate in group Q&A sessions. Role-play scenarios allow students to discuss and practice responding to peer pressure or risky situations.
Assessment Checks: Teacher asks learners to identify and label male and female reproductive parts, explain puberty changes, describe menstruation and ovulation, and outline at least two ways to prevent teenage pregnancy. Learners respond orally, draw diagrams, and participate in scenario discussions to demonstrate understanding.
Notes (Expanded & Detailed): Male reproductive system includes penis, scrotum, and testes, responsible for producing and delivering sperm. Female reproductive system includes vulva, labia, clitoris, ovaries, and uterus, responsible for producing eggs and supporting pregnancy. Puberty involves physical growth, sexual maturation, and emotional changes. Menstruation is the monthly shedding of the uterine lining; ovulation is the release of an egg from the ovary. Teenage pregnancy can be prevented through abstinence, education, contraception, and parental guidance. Emphasize hygiene, respectful discussion, and safe behaviors. Practical activities include diagram labeling, Q&A, and role-play scenarios.

C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Students summarize reproductive structures, puberty changes, and reproductive health importance

Evaluation Method (Expanded)
Exit slip/quiz: Students write one change during puberty and one function of reproductive structures
Teacher will collect slips and provide oral feedback
Assignment (Expanded): Draw and label male and female reproductive systems and explain one puberty change
Follow-up Activity: Observe personal hygiene routines and discuss with parents/guardians
Differentiation / Inclusive Strategies: Use diagrams, handouts, and guided discussion for all learners
