INSTRUCTIONAL PROCEDURES

PERIOD 1: Meaning and characteristics of plants

 

PRESENTATION

TEACHER’S ACTIVITY

PUPIL’S ACTIVITY

STEP 1

INTRODUCTION

The revisits the previous lesson on living things and leads the pupils on a walk within the school compound to collect some samples of common plants

 

Pupils pay attention

STEP 2

EXPLANATION

The teacher then explains that plants are living things that grow in the soil.

She states some examples of plants- grasses, flowers, tomatoes, bushes etc

 

She further explains the classes of plants

1. Vascular plants: The vascular plants are those plants that have specialized cells for conducting water and sap within their tissues, including the ferns, horsetails, flowering plants, conifers and other gymnosperms

2. Non vascular plants: Nonvascular plants are 'lower' plants because they are lower to the ground. Also, nonvascular plants are simple and small in size, such as moss and liverworts. They do not have roots, stems, and leaves, nor do they have a system of tubes to move nutrients.

 

Pupils pay attention and participates

STEP 3

DEMONSTRATION

She explains and demonstrates the characteristics of plants

1. they make their own food in a process called photosynthesis

2. they are rooted in a place but respond to external stimuli by moving their parts

3. Plants grow and die

4. Plants support life

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

PRESENTATION

TEACHER’S ACTIVITY

PUPIL’S ACTIVITY

STEP 1

INTRODUCTION

The teacher revisits the previous lesson on various icons that can be seen on the computer

 

Pupils pay attention

STEP 2

EXPLANATION

The teacher then explains the supercomputers and mainframe computers

1. SuperComputer

The Supercomputer is the very fastest and powerful, and expensive type of computer for processing data. Supercomputers’ size and storage capacity are also huge (can occupy huge premises) designed to process vast amounts of data in a short time with high productivity.

These are specially made to perform multi-specific tasks.

 

Uses of supercomputers

  • In research and study of energy and nuclear weapons and designing the aircraft, airplanes, and flight simulators.
  • Climate research and Weather Forecasting and Prediction of Natural Disasters.
  • Spaceship and Satellite Launching.
  • Used in scientific research laboratories.
  • Used in Chemical and Biological research and for highly calculation complex tasks.

Examples: IBM Roadburner, IBM Blue Gene, Intel ASI Red. PARAM-1000, and CRAY-XMP-14.

 

2. Mainframe Computer

Mainframe computers are multi-programming, high-performance computers, and multi-user, which means they can handle the workload of more than 100 users at a time on the computer.

The storage capacity of the mainframe is enormous, with a high-speed data process as well. As well as handling hundreds of input and output devices at a time.

Uses of Mainframe Computer 

Mainframe computers are mainly used by departmental and commercial organizations like Banks, Companies, Scientific research centers, and governmental departments like railways. These computers can work for 24 hours.

Examples: IBM Es000 series, ICL39 Series, and CDC 6600.

Pupils pay attention and participates

STEP 3

DEMONSTRATION

The teacher then mentions and explains the safety rules to be observed in swimming

1. Shower before entering the pool

2. Don’t swim right after eating

3. Wear your swimming gear before entering the pool

4. Don’t play or run around the swimming area as it is wet and can make you fall down

5. Don’t push or jump on others

6. Use floaters if you’re not yet very good at swimming

7. Obey the pool rules

 

She explains and demonstrates the health benefits of swimming

1. It keeps the heart rate up and takes off some of the stress from the body

2. It builds endurance, muscular strength, and cardiovascular fitness

3. it tones the muscles

4. it helps to maintain healthy weight, heart and lungs

5. it improves mental health and makes one smarter

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

Classification of computer based on size
