$\huge \fbox \colorbox{orange}{Answer }$

Explanation:

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. Slide 2 of the wooden dowels through the holes in the center cup. Insert the ends of the dowels into the holes of the other cups and tape them into place.

The arms are attached to a vertical rod. As the wind blows, the cups rotate, making the rod spin. The stronger the wind blows, the faster the rod spins. The anemometer counts the number of rotations, or turns, which is used to calculate wind speed.

Answer 2

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.
