INSTRUCTIONAL PROCEDURES
PERIOD 1: Excretory system
PRESENTATION | TEACHER’S ACTIVITY | PUPIL’S ACTIVITY |
STEP 1 INTRODUCTION | The teacher revises the previous lesson on body image and self-esteem | Pupils pay attention |
STEP 2 EXPLANATION | She explains the meaning of excretory system The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body. | Pupils pay attention and participates |
STEP 3 DEMONSTRATION | She highlights the organs involved in the excretory system The urinary system is made-up of the kidneys, ureters, bladder, and urethra. Other Excretory Organs Apart from the above-mentioned organs, there are other organs that perform excretion. They are: Skin The skin is the largest organ in the body. Its primary function is to protect the different organs of the body. In addition, the skin excretes sweat. Lungs Lungs are the primary respiratory organs. They help take in oxygen and expel carbon dioxide. But, in this process, they also eliminate some amount of water in the form of vapour. Liver This organ has an important function in excreting waste from the body. It is the first line of defence when it comes to hormones, fats, alcohol, and drugs. In fact, most drugs undergo first-pass metabolism in this organ. The kidneys also eliminate a few drugs. Furthermore, the liver eliminates excess fats and cholesterol. This is essential to maintain the health of the body.

NOTE
Excretory system
The excretory system is a passive biological system that removes excess,
unnecessary materials from the body fluids of an organism, so as to help
maintain internal chemical homeostasis and prevent damage to the body.
Organs involved in the excretory system
The urinary system is made-up of the kidneys, ureters, bladder, and urethra.
Other Excretory Organs
Apart from the above-mentioned organs, there are other organs that perform excretion. They are:
Skin
The skin is the largest organ in the body. Its primary function is to protect the different organs of the body. In addition, the skin excretes sweat.
Lungs
Lungs are the primary respiratory organs. They help take in oxygen and expel carbon dioxide. But, in this process, they also eliminate some amount of water in the form of vapour.
Liver
This organ has an important function in excreting waste from the body. It is the first line of defence when it comes to hormones, fats, alcohol, and drugs. In fact, most drugs undergo first-pass metabolism in this organ. The kidneys also eliminate a few drugs. Furthermore, the liver eliminates excess fats and cholesterol. This is essential to maintain the health of the body.
EVALUATION: 1. Explain the meaning of excretory system
CLASSWORK: As in evaluation
CONCLUSION: The teacher commends the pupils positively
PERIOD 2 and 3: Communicable and non-communicable diseases. Python
PRESENTATION | TEACHEIR’S ACTIVITY | PUPIL’S ACTIVITY |
STEP 1 INTRODUCTION | The teacher revisits the previous lesson on signs and symptoms of diseases | Pupils pay attention |
STEP 2 EXPLANATION | She explains the meaning of communicable diseases and their examples Communicable diseases are ones which are contagious. In other words, it can be transferred from one person to another. Further, it can be done in a direct or indirect manner. Moreover, through direct contact, it can spread via transmission from infected blood, faeces or other fluids of the body. Examples include Tuberculosis, cholera, Influenza, HIV, hepatitis chickenpox, COVID-19, measles etc
Non-communicable diseases are ones which do not spread from one person to the other. Thus, we refer to them as a non-contagious disease. Examples include strokes, excessive hunger, diabetes, frequent urination, blood pressure, cancer, obesity, allergy, hypertension
| Pupils pay attention and participates |
STEP 3 DEMONSTRATION | The teacher explains the meaning of scratch programming language Scratch is a programming language where we can create animations, stories, video games with the help of different features available in this programming language. Components of the scratch screen or the scratch program are as follows: block palette, script area, stage, sprite list, tools, etc. | Pupils pay attention and participate |
STEP 4 NOTE TAKING | The teacher writes a short note on the board | The pupils copy the note in their books |
