🌟 Parts of the weather

Scientists describe weather by temperature, humidity, wind speed and direction, clouds, rain or snow, and air pressure.

🔍 Measuring tools

Weather scientists measure temperature with a thermometer, air pressure with a barometer, wind speed with a spinning anemometer, wind direction with a weather vane, and rain with a rain gauge.

💡 Weather forecasting

Meteorologists gather information from many weather stations, satellites and radar, and use powerful computers to forecast the weather for the coming days.

🎯 Be a weather scientist

You can record the weather every day in a notebook: draw a sun, a cloud or rain, and write the temperature, and after a month see how the weather changed.
