Weather changes — Earth science, 4–6 years
Weather is what the air and sky are like here and now: sunny, cloudy, windy, rainy or cold.
What weather is
Weather is the changing condition of the air around us. We can notice it with our senses: light or dark clouds, moving leaves, rain on our skin, or warm and cold air.
Why notice it?
Knowing the weather helps us choose clothes, decide whether to play outside and protect ourselves from strong sun, cold or storms. People began watching the sky because weather could help or harm travel, crops and animals.
A simple weather record
For three mornings, look outside at the same time. Monday: sunny and still; Tuesday: grey clouds and rain; Wednesday: sunny with moving leaves. The weather changed, even though you watched the same place.
Weather is not climate
A cold or rainy day does not mean every day will be cold or rainy. It is reasonable to mix them up because both describe the air, but weather is what happens now; climate is the pattern noticed over many years.
Weather outside school
Weather forecasts help people pack bags, dry clothes, fly planes, sail boats and care for gardens. A forecast is useful advice, not a promise, because the air can change in ways that are hard to predict exactly.
