![]() ![]() Scientists use anemometers to measure wind speed. Youre all set Find a windy spot and count the number of times the cup with the x rotates around in 30 seconds. Weather science appears at various points in the K-12 science curriculum. Now it’s time to make your own anemometer! You are going to use some simple materials to make a four-cup anemometer and use a fan or natural wind to test out your instrument. Kids will love creating their own patterns and experimenting to find which objects work best. Use these free STEM lessons and activities to explore weather science and climate with K-12 students. When anemometers are attached to the top of wind turbines, the turbines can read this data and be programmed to automatically adjust the angle and direction of the turbine’s blades to make the best use of the wind for efficient energy production. The instrument counts the number of rotations, or turns, which is used to calculate wind speed.Īn anemometer is used by meteorologists to study weather patterns and is also an important tool used on wind farms. To calculate the velocity at which your anemometer spins, determine the number of revolutions per minute (RPM). As wind causes the cups and shaft to turn, the speed of turning can be used to calculate wind speed. EXPLANATION: An anemometer is useful because it rotates with the wind. It is usually made of several small cups attached to a vertical shaft. The faster the wind blows, the faster the cups will spin around the axis. An anemometer is an instrument that measures wind speed. The most common anemometers are vane anemometers, cup anemometers, thermal anemometers, and thermal anemometers with velocity temperature profiling ability. Your students will learn about anemometers as they watch an educational video. They can also be used to measure wind speed of airflow in a contained environment. Anemometers are very useful tools needed to help predict weather conditions. As the wind blows, they “catch” the wind and begin to spin around the axis. Anemometers can be used to determine wind speed in an uncontained environment such as in the open air outside. What Does An Anemometer Look Like Some facts-they can be manufactured-as either a propeller-type or a cup type of air current speed instrument. This instrument uses three or four cups mounted on a vertical pole (axis) and all facing the same direction. There are a few different types of anemometers, but the cup anemometer is the most basic. An anemometer is an instrument used to measure wind speed. In order for wind farms to work efficiently and safely, it is important to be able to accurately measure wind speed. ![]()
