Ask students to raise their hands when they notice a new instrument mentioned in the video. Ask students what each instrument measures or how it works. Can show moisture content of clouds and amount of precipitation. Wind speed is measured with a anemometer. Wind is always recorded and reported as the direction the wind is coming from.
Wind direction is measured with a wind vane.
Knowing wind direction can also help predict type of weather system approaching and possible precipitation. Measured with a barometer. None of them will use expensive materials, but they will work to indicate changes in the weather. Split into five teams. Explain that each team member will build their own instrument, using the worksheet.
