SHS2 General Science · Semester 1 Week 7: Essentials for Survival

Lesson notes

Learning Objectives

Indicator: 2.2.1.LI.1 - Analyse the structure and function of the excretory organs in the human body.

By the end of the lesson, learners can:

Identify and name the four main excretory organs of the human body (kidneys, skin, lungs, liver) and state the primary waste product each removes.
Describe the structural features of the kidney, including the renal cortex, medulla, pelvis, ureter, and bladder, and explain how each part supports the kidney’s function.
Relate the structure of the skin (sweat glands, pores) and lungs (alveoli, moist surfaces) to their excretory roles.
Use a model, chart, or video to analyse and explain, in small groups, how at least two excretory organs work together to maintain a healthy body.
Construct a simple labelled diagram of the urinary system showing the pathway of urine from kidney to the outside of the body, and explain the function of each labelled part.
