Measuring Wind Strength
Students will make an anemometer to measure wind strength.
SettingInside and Outside
- S4E4. Students will analyze weather charts/maps and collect weather data to predict weather events and infer patterns and seasonal changes.
- a. Identify weather instruments and explain how each is used in gathering weather data and making forecasts (thermometer, rain gauge, barometer, wind vane, anemometer).
- c. Use observations and records of weather conditions to predict weather patterns throughout the year.
- CCSS.MATH.CONTENT.4.MD.C.6 Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.
- Plastic protractors (1 per small group)
- Ping-pong balls (1 per small group)
- Tape or glue
- Distribute materials and lead students in following the directions on the following website to build their anemometers: https://www.canada.ca/en/environment-climate-change/services/sky-watchers/teacher-corner/build-your-own-anemometer.html
- Out in the schoolyard, model for students how to hold the protractor parallel to the ground at shoulder height, pointing into the wind, while a partner reads the displacement on the protractor (the conversion chart for degree angles to miles per hour is provided on the website).
- Record data each day for two weeks to determine the prevailing wind patterns of that time of year at your school.
