How Do We Measure Weather? - We learned that weather is what the atmosphere is like at a given place and time and meteorologists are scientists who study weather. Meteorologists measure air temperature, cloud cover, and precipitation. Next we learned about tools meteorologists use such as a wind vane, anemometer, barometer, and hygrometer. Then we learned that a wind vane measures wind direction and an anemometer measures wind speed while a barometer measures air pressure and a hygrometer measures water vapor or humidity in the air. Then we learned how data is gathered through radiosonde and the importance of weather reports.

Then we learned how data is gathered through radiosonde and the importance of weather reports. We conducted an experiment where we created a barometer from a jar and a balloon. Then we placed it outside to measure changes in air pressure. After a few hours we noticed a change in air pressure by the expansion of the balloon. We played a game where we answered questions relating to weather. We took a quiz on instruments used to measure weather.
