In this social science chapter 2 Understanding the Weather, students will explore how we describe and measure different weather conditions like temperature, rainfall, humidity, wind, and atmospheric pressure.
Weather affects our daily lives in many ways—from the clothes we wear to the food we eat and the activities we plan. You will learn how traditional knowledge and modern instruments are used to observe and predict weather changes. With increasing climate-related challenges, understanding weather has become more important than ever. This chapter connects scientific tools with everyday experiences, helping learners appreciate the environment around them.

Understanding the Weather Notes
1. What is Weather?
- Weather is the condition of the Earth’s atmosphere at a particular time and place.
- The layer where weather occurs is the troposphere, the lowest layer of the atmosphere.
2. Elements of Weather
- Temperature – how hot or cold the air is.
- Precipitation – rain, snow, sleet, or hail.
- Atmospheric Pressure – the weight of air above us.
- Wind – movement of air.
- Humidity – the amount of water vapor in the air.
3. Traditional Weather Forecasting
- Observing animals (frogs croaking, ants moving eggs) and natural signs (pine cones closing) has been a method of traditional forecasting.
4. Modern Weather Instruments
- Thermometer – measures temperature (°C or °F).
- Rain Gauge – measures rainfall in mm.
- Barometer – measures atmospheric pressure (in millibars).
- Wind Vane – shows wind direction.
- Anemometer – measures wind speed (km/h).
- Hygrometer – measures humidity (%).
5. Automated Weather Stations (AWS)
- Use digital sensors to collect weather data automatically.
- Help predict extreme weather like cyclones, floods, and droughts.
