Lesson notes

Learning Objectives

Indicator: B3.3.1.1.1 - Explain that the external parts of the human body work interdependently to perform a function

By the end of the lesson, learners can:

Identify at least five external parts of the human body and state their individual functions.
Explain, with examples, how two or more external body parts work together to perform a single task.
Demonstrate through physical activities (such as skipping or playing football) how different body parts cooperate to complete an action successfully.
Discuss why every external body part is important and why each one must be cared for and protected.

Exemplars (from the NaCCA curriculum)

- Engage pupils in songs on the various parts of the body, e.g. head, shoulders, knees and toes, show me your head, my head, my shoulders my knees, my toes.
- Learners brainstorm on how the various parts of the human body support each other to perform various functions, e.g. assuming a dog is barking towards you, how do the eyes, ears, feet help you to recognise danger and escape?
- Learners engage in various activities (skipping), playing football and explain how the various parts of the body contribute to undertake the activity successfully.
NB: The key lesson for learners is to appreciate the fact that every part of the body is important and must be taken care of.
