OBJECTIVES:
An anemometer is an instrument used to determine
the wind's force or speed. The Wright brothers used
an anemometer to determine the wind's speed as they
experimented with their flying machines. This information
was used to: calculate the amount of lift and drift (drag) on
their flying machines and to correlate flying machine
performance trends under different conditions.
This anemometer is an example of a vertical-axis wind collector.
Students are introduced to the purpose and operation
of an anemometer.
Students construct a cup anemometer.
Students utilize the anemometer under different wind
conditions and graph results.

LECTURE AND PREPARATION TIME:
30 minutes
LESSON TIME:
Two 60 minute class periods
WORDS TO KNOW:
- anemometer
- force
- RPM - revolutions per minute
- speed
- velocity
- vertical-axis
SPECIAL NOTES:
*Although the science concepts and vocabulary are
intended for middle school students,
younger and older students may enjoy this activity.
This paper cup anemometer will produce a
reasonable approximation of circumferential velocity, but should not be
used for any purpose other than elementary illustration.
