SHS1 General Science · Semester 2 Week 9: The Human Body and Health

Lesson notes

Learning Objectives

Indicator: 1.4.1.LI.1 - Explore common risks and hazards in the environment and how to address them.

By the end of the lesson, learners can:

Identify at least five common hazards in the home and workplace and classify each as physical, chemical, biological, or ergonomic.
Explain the difference between a hazard (a potential source of harm) and a risk (the likelihood of that harm occurring) using everyday examples.
Assess a local workplace or familiar environment to identify potential risks and hazards and propose practical control measures for each.
Apply the hierarchy of hazard control (elimination, substitution, engineering controls, administrative controls, personal protective equipment) to recommend solutions for identified hazards.
Justify the importance of hazard awareness and reporting in protecting personal and community health, using reasoning based on evidence gathered from a local visit or case study.
