INSTRUCTIONAL PROCEDURES

PERIOD 1: Mirror image formation

PRESENTATION

TEACHER’S ACTIVITY

PUPIL’S ACTIVITY

STEP 1

INTRODUCTION

The teacher revisits the previous lesson and introduces the new topic by explaining what a Mirror is and what mirror image formation is-

Mirror is a shiny surface that reflects all the light that strikes it

 

Mirror Image Formation- this is when an object is placed in front of a mirror and the same object is seen in the mirror

Pupils pay attention

STEP 2

EXPERIMENTATION

The teacher demonstrates image formation using a mirror and any of the learners who stands in front of it

Pupils pay attention and participates

STEP 3

DEMONSTRATION

Using real mirrors, she further explains and demonstrates the types of mirrors

1. Concave mirror- it has an inward curvature at the centre

2. Convex mirror – it has an outward bulge

 

She further explains the applications of reflection of light

1. We could see ourselves clearly in the mirror

2. It is used to produce objects such as a torch light and headlamp for seeing near and far objects

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

 

NOTE

Mirror is a shiny surface that reflects all the light that strikes it

Mirror Image Formation- this is when an object is placed in front of a mirror and the same object is seen in the mirror

Types of mirrors

  1. Concave mirror- it has an inward curvature at the centre
  2. Convex mirror – it has an outward bulge

 

Applications of reflection of light

  1. We could see ourselves clearly in the mirror
  2. It is used to produce objects such as a torch light and headlamp for seeing near and far objects

EVALUATION:    1. Define these terms

  1. Mirror b. Mirror image formation
  2. What are the two types of Mirror?
  3. What are the applications of the reflection of light in our daily lives?

CLASS ACTIVITY: Pupils in pairs, demonstrate the reflection of light using plane mirrors

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively

PERIOD 2 and 3: Hardware devices. Physical fitness

PRESENTATION

TEACHER’S ACTIVITY

PUPIL’S ACTIVITY

STEP 1

INTRODUCTION

The teacher revisits the previous lesson and introduces the new topic by explaining what Hardware devices are-

 

Hardware devices are physical parts of the computer that could be seen and touched.

Pupils pay attention

STEP 2

EXPLANATION

The teacher using the chart, describes the two forms of hardware devices

a. Input devices: they are used to enter commands, data and instructions into the computer e.g mouse, joystick, scanner, microphone, keyboard etc

b. Output devices: They are used to retrieve data, results and information from the computer system e.g monitor, printer, speakers etc

Pupils pay attention and participates

STEP 3

DEMONSTRATION

She displays the hardware devices for the pupils to identify

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

 

NOTE

Hardware devices are physical parts of the computer that could be seen and touched.

Two forms of hardware devices

  1. Input devices: they are used to enter commands, data and instructions into the computer e.g mouse, joystick, scanner, microphone, keyboard etc
  2. Output devices: They are used to retrieve data, results and information

from the computer system e.g monitor, printer, speakers etc

EVALUATION:    1. Define the term “Hardware devices”

  1. Describe the two forms of hardware devices there are

                             and give three examples of each

CLASS ACTIVITY: Pupils in small groups, identify and state the various hardware devices

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively
