OUR WEATHER

Weather is the the condition of the atmosphere for a very short period of time hence the weather may be cloudy in the morning and be sunny some few minutes later. Therefore the weather may be sunny, windy , cloudy, or hot

There are different factors that affect weather, these are:

1. Wind
2. Sunshine
3. Rainfall
4. Temperature
5. Humidity
6. Cloud
7. Atmospheric pressure

Weather instrument and functions

The following are weather instruments:

1. Thermometer – it is used to measure the temperature of a person.
2. Barometer – it is used to measure the pressure of the atmosphere.
3. Anemometer – it is used to measure the speed of the wind.
4. Rain gauge – it is used to measure the quantity or amount of rainfall.
5. Hygrometer – it is used to measure water vapor in the air (relative humidity).
6. Clock – it is used to show time.
7. Photometer – used to measure Light intensity.
8. Wind Vane – It is used ti measure the direction of the wind

Weather Symbols

Meteorologist make use of these symbols when recording and forecasting weather.

The following are some of the symbols used to observe the condition of weather.

1. Sunny
2. Rainy
3. Cold
4. Cloudy
5. Lightning
6. Hot

 

 

 

GLOBAL WARMING

Global warming is an increase in the average temperature of the earth’s atmosphere that leads to the change of climate.

This is caused by the release of harmful gases like carbon dioxide (co2), chlorofluorocarbons (CFCs) into the atmosphere.

The effect of global warming

1. Rising sea level
2. Increase in temperature
3. Excessive flood.

 

 

Presentation

The topic is presented step by step

 

Step 1:

Step 2.

He introduces the new topic

 

Step 3:

The class teacher allows the pupils to give their own examples and he corrects them when the needs arise

2. Identify the factors affecting weather.
3. Mention weather instruments
4. Identify and write simple weather symbols.

 

Conclusion :

 

The class teacher wraps up or conclude the lesson by giving out short note to summarize the topic that he or she has just taught.

The class teacher also goes round to make sure that the notes are well copied or well written by the pupils.

He or she does the necessary corrections when and where  the needs arise.
