Project short descriptionAn?anemometer?is a device that is used to measure wind speed. There are many different types of anemometers suited for different environments, situations, and measurements. A?cup anemometer?is a basic type of measuring device, while newer, more accurate anemometers can make use of lasers and ultrasonic measuring technology.A cup anemometer is commonly called a?Robinson anemometer.?It uses cup-like shapes to catch the wind, causing the device to spin. How many times it spins in a given time interval can tell you how fast the wind is moving. In this experiment, we'll learn how to make an anemometer and calibrate it.ObjectiveLearn how to make an anemometer.Materials5 small paper cupsHole punchScissorsDuct tape3 thin wooden dowelsEmpty water bottleStopwatchprocedureUse the hole punch to make a hole in the side of each of the 4 paper cups.Use the hole punch to make 4 holes spaced evenly around the rim of the last cup. This will be the center of the anemometer.Slide 2 of the wooden dowels through the holes in the center cup. They should cross in an “X.”Insert the ends of the dowels into the holes of the other cups and tape them into place. Make sure the cups are all facing the same direction.Take the last wooden dowel and make a hole in the bottom of the center cup.Push the dowel up until it meets the X and tape everything together. This will be your rotation axis.Put the center dowel into an empty water bottle and begin testing!to calibrate your anemometer1. On a windless day, have an adult drive you down the street at 10 kilometres/miles per hour.2. Hold the anemometer out the window and count the number of rotations in 30 seconds.3. However many times your anemometer spins in 30 seconds will correspond roughly to wind blowing at 10 miles per hour.WhyCalibrating your anemometer gives you a basis to compare your collected data. For example, if your anemometer spins 10 times in 30 seconds on your 10 kilometre/mile per hour test run, then you know in the future that 10 spins in 30 seconds means the wind is going 10 miles an hour. If you want to be even more accurate, you can calibrate at many different speeds and make a chart of your results.Picture description27717750lefttop Things to do after finishing the projectTake a picture of every step of projectUse smartphone or computer software to make a short video clip (movie) from pictures (PROJECT FOR Q1)Record video message using smartphone, don’t exceed 1 minute of recording timeStart a video message by presenting yourself, presenting your class, presenting your project name, show what did you use during experiment, and what are the results of your experiment.Pictures, short video clip (movie) from pictures, and video message, send to teacher on e-mail, whatsapp or USB flash pleting task from number 3-5 is for the quarter 2.
