MATERIALS:
- 5 three ounce paper Dixie Cups
- 2 soda straws
- pin
- paper punch
- scissors
- stapler
- sharp pencil with an eraser
PROCESS:
Take four of the Dixie Cups and use the paper punch to punch one hole in each, about a half inch below the rim.
Take the fifth cup and punch four equally spaced holes about a quarter inch below the rim. Then punch a hole in the center of the bottom of the cup.
Take one of the four cups and push a soda straw through the hole. Fold the end of the straw and staple it to the side of the cup across from the hole. Repeat this procedure for another one-hole cup and the second straw.
Slide one cup and straw assembly through two opposite holes in the cup with four holes. Push another one-hole cup onto the end of the straw just pushed through the four-hole cup.
Bend the straw and staple it to the one-hole cup, making certain that the cup faces the opposite direction from the first cup. Repeat this procedure using the other cup and straw assembly and the remaining one-hole cup.
Align the four cups so that their open ends face in the same direction either clockwise or counter-clockwise around the center cup.
Push the straight pin through the two straws where they intersect.
Push the eraser end of the pencil through the bottom hole in the center cup. Push the pin into the end of the pencil eraser as far as it will go.
Now your anemometer is ready for use!
EXPLANATION:
An anemometer is useful because it rotates with the wind. To calculate the velocity at which your anemometer spins, determine the number of revolutions per minute (RPM). Next, calculate the circumference (in feet) of the circle made by the rotating paper cups. Multiply your RPM value by the circumference of the circle and you will have an approximation of the velocity of at which your anemometer spins (in feet per minute). Your anemometer doesn't need to be pointed in the wind for use.
Note: Some forces are being ignored including drag and friction for this elementary illustration, so the velocity at which your anemometer spins is not the same as wind speed

Who made first the anemometer?
The anemometer has no precisely known inventor. The first recorded description of an anemometer was by Leon Battista Alberti in 1450. The cup anemometer was invented in 1846 by Dr. John Thomas Ronrey Robinson.
What materials are used to make a cup anemometer?
A cup anemometer is typically made from lightweight materials such as plastic or metal, with three or four cups attached to the ends of horizontal arms. The cups may also be made of metal or a durable plastic material to withstand weather conditions.
How do you make a wind speed measure?
You need an anemometer.
How to calibrate a homemade anemometer?
To calibrate a homemade anemometer, you can compare its readings to a known standardized anemometer in the same conditions. Make adjustments to your homemade anemometer based on these comparisons until its readings are consistent with the known device. Regularly repeat this process to ensure accurate measurements.
How do you make cup anemometer?
using pvc elbows etc
Who made the anemometer?
Leone Battista Alberti did in the 15th centery *-* ().() xD
What does an anemometer detect?
An anemometer detects wind speed.
How is an anemometer calibrated?
The anemometer cups are taken off and a metal disc substituted. This is spun and the time taken to "run down" to a certain speed is observed, and if within specifications for that type of anemometer, the machine is OK for use.
What is the use of anemometer?
An anemometer is used for weather forecasting by meteorologists.
Why is a anemometer called a anemometer?
The term "anemometer" comes from the Greek words "anemos," meaning wind, and "metron," meaning measure. So, an anemometer is a device used to measure wind speed and direction.
What Marvin Rosaroso learn and do with the result of discovered an anemometer?
Marvin Rosaroso likely learned about the measurement of wind speed and direction using an anemometer. He may have used the results to track weather patterns, gather data for scientific research, or improve safety measures in outdoor activities such as sailing or aviation.
