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

INSTRUCTIONAL MATERIALS: wood, orange, apple, mango, specimen of vegetables, charts on the uses of plants, swimming pool, floater, tube/rubber, swimming trunk, swimming cap, swimming goggle, life jack pictures of mini computers and micro computers

INSTRUCTIONAL PROCEDURES

PERIOD 1: Uses of plants

NOTE

Lifespan means the length of time for which a person or thing lives/functions

Classes of plants based on their life spans

1. Annual plants: These are plants that perform their entire life cycle from seed to flower to fruits and die in one year e.g water melon, peas, maize rice, sweet potatoes etc
2. Biennial plants: These are plants that perform their entire life cycle from seed to flower to fruits and die in two years. During the first growing season biennials produce roots, stems, and leaves; during the second they produce flowers, fruits, and seeds, and then die. Sugar beets and carrots are examples of biennials.
3. Perennial plants: A perennial plant or simply perennial is a plant that lives more than two years. Examples are Irish potatoes, peonies etc

Uses of plants

1. Plants protect us from air pollution
2. Plants give us materials like gum, paper, rubber etc
3. Plants are a great source of timber and wood
4. Plants help in soil erosion
5. Plants give us oxygen which we breathe for survival
6. We can make medicines from plants
7. We can eat plants as food

EVALUATION:    1. What does the word ‘life-span’ mean?

2. Classify plants based on their lifespan and give two examples of each
3. Discuss four uses of plants

CLASS ACTIVITY: Pupils in small groups analyse the importance of plants to our environment

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively

PERIOD 2 and 3: Classification of computer by size. Swimming  

NOTE

Classification of computer based on size

3. Minicomputer is a digital and multi-usercomputer system with the connection of more than one CPU. Thus, many people can work on these computers simultaneously instead of a single person. Also, it can process with other accessories like a printer, plotter, etc.

Minicomputers are the medium type of computers that have more functionality power and are expensive than microcomputers. On the other hand, the size, storage, and speed of minicomputers are large but less than the mainframe and supercomputers.

Uses of Minicomputers –

The minicomputers are used as real-time applications in Industries, bookings, and Research Centres. Banks also use minicomputers for preparing payroll for employees’ salaries, records, tracking of financial accounts, etc.

Examples: PDP 11 and IBM (8000 Series).

4. Micro Computer

The most common computer used at home today is the microcomputer. With the invention of the microprocessors in the year 1970, it became possible to use computers for people personally at a low cost and reasonable price known as Digital Personal Computer.

The design of microcomputers is minimal in size and storage capacity. These computers consist of many parts like Input and Output devices, Software, operating systems, networks, and Servers

Examples of micro computers include PC or laptop, smartphone, Tablet, PDA, server, palmtop, and workstation.

This can be installed in any work area or even at home for personal use

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

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

EVALUATION:    1. What are Mini computers? State two uses of the mini computers. Give two examples of each

2. What are Micro computers? State two uses of the Micro computers. Give two examples of each
3. Explain five safety rules in swimming
4. Discuss four health benefits of swimming

CLASS ACTIVITY: Pupils in small groups discuss the health benefits of swimming as it affects them

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively
