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 TAKING

The teacher writes a short note on the board

The pupils copy the note in their books

  2. Mention and describe other organs in the 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
