Answer:
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!
Anemometer Diagram
To calibrate your anemometer:
On a windless day, have an adult drive you down the street at 10 miles per hour.
Hold the anemometer out the window and count the number of rotations in 30 seconds.
However many times your anemometer spins in 30 seconds will correspond roughly to wind blowing at 10 miles per hour.
Anemometer Demonstration
Why?
Calibrating 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 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.
