B5 Science · Term 2 Week 5: The Human Body Systems

Lesson notes

Learning Objectives

Indicator: B5.3.1.1.1

By the end of the lesson, learners can:

Identify and name at least four parts of the respiratory system in humans (nose, trachea, lungs, diaphragm) when shown a chart, model, or diagram.
Describe the function of each major part of the respiratory system in simple terms.
Explain why breathing is important for the human body.
Draw and label the main parts of the respiratory system.
Construct a simple breathing model using everyday materials to demonstrate how the lungs and diaphragm work.

Suggested placement: Term 2, Week 5 (Week 17 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

- Introduce the lesson with songs on the parts of the body, e.g. head, shoulders, knees and toes.
- Ask learners to breathe in and out for some time.
- Relate the act of breathing to the respiratory system and guide learners to identify the organs of the system using charts or models.
- Use role-play to guide learners to identify the functions of each part (different learners assume and role-play the functions of parts of the respiratory system,
e.g. Ama is the lungs and Amina is the diaphragm).
- Engage learners in an activity to design a breathing model using plastic bags, balloons, rubber bands and polythene bags.
- Learners draw and label the respiratory system and state its function.
- Learners are tasked to find out the diseases and lifestyles that affect the respiratory system adversely.
Project: Assist learners to design an improvised breathing apparatus using plastics.
