How will you make anemometer using materials found around you?
Answers
An 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.

Objective
Learn how to make an anemometer.
Materials:
- 5 small paper cups
- Hole punch
- Scissors
- Duct tape
- 3 thin wooden dowels
- Empty water bottle
- Stopwatch
Procedure:
- Use 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!
