  3. Primary 2
  4. The senses - smell + Features of a CPU + Movement

Term: 1st Term

Week: 5

Class: Primary 2

Age: 7 years

Duration: 40 minutes of 3 periods

Date:

Subject: Basic Science and Technology

Topic:-       The senses - smell

  • Features of a CPU
  • Movement

SPECIFIC OBJECTIVES: At the end of the lesson, pupils should be able to

  1. Use the sense of smell to recognize pleasant and unpleasant odours
  2. State the importance of the smell
  3. Identify the different features of the CPU and state its functions
  4. Identify safety rules in movement

INSTRUCTIONAL TECHNIQUES: Identification, explanation, playway method, questions and answers, demonstration, videos from source

INSTRUCTIONAL MATERIALS: first aid materials, fruits-orange, mango, pawpaw, banana etc, flowers, socks, shoes, food drinks-beverages

INSTRUCTIONAL PROCEDURES

PERIOD 1: The sense of smell

PRESENTATION

TEACHER’S ACTIVITY

PUPIL’S ACTIVITY

STEP 1

INTRODUCTION

The teacher revises the previous lesson on the organ of hearing

Pupils pay attention

STEP 2

EXPLANATION

The teacher explains the meaning of smell

 

Smell is the sense by which people take in scents through their nose, or an odor or the act of sensing or giving off an odor

Pupils pay attention and participates

STEP 3

INTERACTIVE SESSION

She then explains the importance of smell

1. It can alert us to danger like gas leak, fire or rotten food

2. It is closely linked to parts of the brain that process emotion and memory

3. Unpleasant and bad smells actually send pain signals to the brain to warn us of possible danger.

 

Pupils pay attention and participate

STEP 4

NOTE TAKING

The teacher writes a short note on the board

The pupils write the notes in their books

 

NOTE

Smell is the sense by which people take in scents through their nose, or an odor or the act of sensing or giving off an odor

Importance of smell

  1. It can alert us to danger like gas leak, fire or rotten food
  2. It is closely linked to parts of the brain that process emotion and memory
  3. Unpleasant and bad smells actually send pain signals to the brain to warn us of possible danger.

 

EVALUATION:    1. Explain the meaning of smell

  1. Explain the importance of smell

CLASS ACTIVITY: Using the sense of smell, the pupils are asked to associate the smell of different substances to either pleasant or unpleasant smells

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively

PERIOD 2 and 3: Features of a CPU. Movement

PRESENTATION

TEACHER’S ACTIVITY

PUPIL’S ACTIVITY

STEP 1

INTRODUCTION

The teacher revisits the previous lesson on digital and hybrid computers. The teacher introduces the new topic by stating the main features of the CPU; Control unit, Arithmetic and Logic Unit and Memory unit

 

Pupils pay attention

STEP 2

EXPLANATION

The teacher then explains the various functions of the control unit

1.   Fetching instructions one by one from primary memory and gather required data and operands to perform those instructions.

2.   Sending instructions to ALU to perform additions, multiplication etc.

3.   Receiving and sending results of operations of ALU to primary memory

4.   Fetching programs from input and secondary memory and bringing them to primary memory

5.   Sending results from ALU stored in primary memory to output

Pupils pay attention and participates

STEP 3

DEMONSTRATION

She further explains what movements means

Movement is the change in position

 

She explains and demonstrates some movement as the pupils do the same e.g leaping, hopping, running, stepping, catching of objects, throwing of objects, striking of objects, etc

 

She performs the basic movement patterns

 

She further states the safety rules in making movement

1. only carry out the movement when your teacher is around

2. do the movement gently

3.  Don’t do any movement if you are sick, weak or tired

4. Don’t do a movement that is too difficult for you

 

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

Control Unit and its functions

Control Unit is the director of all operations in the CPU

 

Functions of the control unit

  1. Fetching instructions one by one from primary memory and gather required data and operands to perform those instructions.
  2. Sending instructions to ALU to perform additions, multiplication etc.
  3. Receiving and sending results of operations of ALU to primary memory
  4. Fetching programs from input and secondary memory and bringing them to primary memory
  5. Sending results from ALU stored in primary memory to output

 

MOVEMENT

Movement is the change in position e.g leaping, hopping, running, stepping, catching of objects, throwing of objects, striking of objects, etc

Safety rules in making movement

  1. only carry out the movement when your teacher is around
  2. do the movement gently
  3. Don’t do any movement if you are sick, weak or tired
  4. Don’t do a movement that is too difficult for you

 

EVALUATION:    1. What are the features of the CPU?

  1. Describe three functions of the Control unit
  2. Define the term ‘movement’
  3. List five examples of movement
  4. Discuss three safety rules in making movements

CLASS ACTIVITY: Pupils in small groups perform correct patterns in manipulative movement

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively
