![]() They usually display the wind speed in miles per hour (mph) or kilometers per hour (kph). Real anemometers are calibrated, meaning that a certain rotation speed corresponds to a known wind speed. The anemometer's rotation speed can then be used to determine the wind's speed. This means that when the wind blows, it pushes on one side of the anemometer harder, causing it to spin. The open sides of the cups "catch" the wind more than the closed sides. The cups are aligned so they all face the same direction around a circle (all clockwise or all counterclockwise). A cup anemometer has three or four cups mounted about a vertical axis that can spin (Figure 1). There are several different types of anemometers. Patterns of change can be used to make predictions.Īn anemometer is an instrument that is used to measure wind speed. Scientists record patterns of the weather across different times and areas so that they can make predictions about what kind of weather might happen next. Represent data in tables and various graphical displays (bar graphs and pictographs) to reveal patterns that indicate relationships. Make predictions about what would happen if a variable changes.Īnalyzing and Interpreting Data. Planning and Carrying Out Investigations. This lesson focuses on these aspects of NGSS Three Dimensional Learning: Science & Engineering Practices Represent data in tables and graphical displays to describe typical weather conditions expected during a particular season. This lesson helps students prepare for these Next Generation Science Standards Performance Expectations: Understand the relationship between wind speed and how fast an anemometer rotates.Understand what an anemometer is and what it measures. ![]() Then do a simple experiment in which students change the "wind" speed using a fan and measure how fast their anemometer spins. Help the budding meteorologists in your classroom learn how to measure wind speed by building their own anemometers (wind speed meters) with paper cups and straws.
