INSTRUCTIONAL PROCEDURES

PERIOD 1: Pollution

NOTE

Land and noise pollution

Land pollution is what we call things that hurt our land. When our waste products get scattered on the land, this causes pollution.

Noise pollution are unwanted or disturbing sound in the environment that affects the health and well-being of humans and other living organisms

Types of Land pollution

1. Agricultural Land Pollution. We use a lot of fertilizers as well as pesticides, fungicides, and insecticides on our agricultural land in a bid to maximize yields.
2. Non-biodegradable Solid Waste.
3. Industrial Waste.
4. Deforestation.
5. Mining.

Effects of land pollution

1. Toxic substances may leech into the soil and cause contamination.
2. Water bodies get contaminated as well.
3. Increased risk of wildfires.
4. Topsoil gets lost.
5. May cause birth defects if exposed to contamination.
6. Can negatively affect the quality of life and also health.

Types of Noise Pollution

Primarily there are two main reasons for Sound Pollution that can occur. They are:

1. Man-Made Noise Pollution – These include a wide range of noise disruption that occurs as a result of man-made noise like, vehicles, honking, Air traffic, construction, fights, loud music, and various other household noises.
2. Environmental Noise Pollution – These are noise emitted as a result of environmental issues like Earthquakes, thunderstorms, Volcanic eruptions, howling of animals, etc.

EFFECTS OF NOISE POLLUTION

1. Respiratory agitation
2. racing pulse
3. high blood pressure
4. headaches
5. in case of extremely loud, constant noise, gastritis, colitis and even heart attacks

How to prevent and control land pollution and noise pollution

Land pollution

1. Reducing Chemical Fertilizers and Pesticides. Plants require soil nutrients such as nitrogen, calcium and phosphorous for growth and development.
2. Forests and grassland vegetation bind soil to keep it intact and healthy.
3. Solid Waste Treatment.
4. Recovering and Recycling Material.

Noise pollution

1. Turn off Appliances at Home and offices. 
2. Shut the Door when using noisy Machines. 
3. Use Earplugs. 
4. Lower the volume. 
5. Stay away from Noisy area. 
6. Follow the Limits of Noise level. 
7. Control Noise level near sensitive areas.
8. Go Green by planning trees.

EVALUATION:    1. Explain the meaning of

1. land pollution
2. noise pollution
3. Describe two types each of
4. land pollution
5. noise pollution
6. State three effects of
7. land pollution
8. noise pollution
9. Outline three ways each we can prevent and control
10. land pollution
11. noise pollution

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively

PERIOD 2 AND 3: High jump, Networking

NOTE

High jump is an athletic event in which a competitor has to jump over a high bar set between two vertical supports.

Phases in high jump

1. The approach or run-up
2. The take-off
3. The flight
4. The landing
5. The recovery

Networking

computer networking, is the practice of transporting and exchanging data between nodes over a shared medium in an information system

Types of computer networking

1. Personal area network (pan)
2. Local area network (LAN)
3. Wireless local area network (WLAN)
4. Metropolitan area network (man)
5. Wide area network (wan)
6. Storage area network (san)
7. Virtual private network (VPN)

Uses of computer networks

1. Communication. Everything, from the world wide web to online banking to multiplayer computer games, depends on the ability of computers to communicate.
2. Accessing resources.  
3. Centralisation of data.  
4. Transfer of files.
5. Increased productivity.  
6. Leisure.
7. Wired network.

EVALUATION:    1. Define High jump

2. What are the phases in High jump?
3. Define ‘Networking’
4. Outline and explain four examples of computer networks
5. State four uses of computer networks

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively
