- Learners discuss mental changes they experience or have noticed in peers, such as mood swings, increased curiosity, and changes in thinking and reasoning.
- Learners discuss social and cultural changes, including new responsibilities, respect for elders, peer interactions, and expectations from family and community.
- Learners work in small groups to create a chart listing one example of physical, mental, and social change for boys and girls.
- Learners share their charts with the class, explaining why each change is important and how it affects daily life.
Assessment Checks:
- Teacher asks: “Name one physical change that happens during puberty.” (Expected answer: Growth spurts, hair growth, or voice change)
