SHS2 General Science · Semester 1 Week 15: Essentials for Survival

Lesson notes

Learning Objectives

Indicator: 2.2.1.LI.2 - Describe the structure of the lungs and investigate the products of aerobic respiration.

By the end of the lesson, learners can:

Identify and describe the main parts of the human lungs, including the trachea, bronchi, bronchioles, alveoli, and diaphragm, using models, charts, or videos.
Explain how the structure of the alveoli is adapted for efficient gas exchange during breathing.
Investigate the products of aerobic respiration through a simple demonstration or experiment and state that carbon dioxide, water, and energy are produced.
Write the word equation for aerobic respiration and explain what happens to the energy released.
Distinguish clearly between breathing (ventilation) and respiration as chemical processes, correcting common misconceptions.

Strand: Processes for Living (Strand 2)
Sub-strand: Essentials for Survival (2.1)
Content standard: 2.2.1.CS.2 - Demonstrate knowledge and ability to carry out research on how air moves in and out of humans. 2.2.1.LO.2 Recognise and explain that the energy released during respiration is used to drive processes in the human body.
Indicator: 2.2.1.LI.2 - Describe the structure of the lungs and investigate the products of aerobic respiration.
Suggested placement: Semester 1, Week 15 (Week 15 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)

Group work/collaborative Learning:
- With the aid of Models, videos, and charts, learners describe the structure of the human lungs in whole class discussion.
- In differentiated learning groups, use think-pair-share to investigate the products of aerobic respiration, supported by models, books, pictures, videos and internet sources.
- Learners reflect on the concepts of breathing and respiration and discuss the misconceptions between the two concepts.
Teaching and Learning Resources:
- Models or videos, pictures/charts/books and internet resources showing aerobic respiration.
- Models/pictures/charts or videos and internet resources
- Books
- Journals
