Hello, young learners! Welcome back to Primary 4 Basic Science and Technology. In our previous lesson, we learned about Weather. Today, we’re going to learn about Weather.
Objectives
By the end of this lesson, you should be able to:
- Identify weather symbols and a weather table.
- Interpret a weather table.
Weather
Weather is the state of the atmosphere at a particular time and place. It describes the conditions we experience outside, such as temperature, sunshine, rain, wind, and clouds.
What is Weather?
Weather is what we experience outside on any given day. It’s a combination of factors like temperature, wind, rain, sunshine, and clouds.
Weather Symbols
There are many different weather symbols used to represent different weather conditions. Some of these symbols include:
- Sunny: A sun symbol represents clear, sunny weather.
- Partly Cloudy: A sun partially covered by clouds indicates partly cloudy conditions.
- Cloudy: Cloud symbols represent overcast or cloudy weather.
- Mostly Cloudy: A mix of sun and clouds is indicated by a sun partially covered by clouds and accompanied by a raindrop or two.
- Rainy: Raindrops symbolize rainy weather.
- Thunderstorm: A thundercloud with a lightning bolt represents a thunderstorm.
- Tornado: A tornado symbol represents a tornado or tornado watch.
- Snowy: Snowflakes represent snowy conditions.
- Foggy: A fog symbol indicates foggy weather.
Keeping Weather Records
We can keep track of weather changes over time by using a weather table. A weather table is a chart that shows the weather conditions for each day. It usually includes information like the date, temperature, wind speed, precipitation, and cloud cover.
Weather Forecast
A weather forecast is a prediction of what the weather will be like in the future. Weather forecasters use weather data and computer models to make these predictions.
Weather Factors
There are several factors that affect weather. Some of the major factors are:
- Temperature: The temperature of the air is one of the most important factors that affect weather.
- Humidity: Humidity is the amount of moisture in the air.
- Air pressure: Air pressure is the weight of the air pressing down on the Earth’s surface.
- Wind: Wind is the movement of air from areas of high pressure to areas of low pressure.
- Precipitation: Precipitation is any form of water that falls from the clouds, such as rain, snow, sleet, or hail.
Evaluation
Now that you’ve learned about weather, let’s see if you can answer these questions:
- Can you name at least three weather symbols and what they represent?
- How do you keep a weather record using a weather table?
- Explain the importance of understanding weather for daily life.
Conclusion
Understanding weather is important for our daily lives. It helps us plan our activities and stay prepared for different weather conditions. Remember to check the comments section if you have any questions, and use the navigation to move to the next lesson. See you in the next lesson!
