The root word "meter" means a way to measure. An anemometer is a weather instrument that measures wind speed.
The prefix "fore" means before.
A meteorologist who uses tools and instruments to collect data and study the weather is able to forecast the weather before the weather happens. Discuss the importance of this through class interaction and discussion.
Before students are grouped explain that each group will have 30 minutes to
read directions
assemble an anemometer
record four anemometer readings (each child has a turn)
use the formula provided to calculate each wind speed.
Formula: To calculate wind speed in miles per hour, multiply the number of complete rotations the colored cups makes in 30 seconds by the diameter (in inches) of the anemometer. Then divide this number by 168.
To calculate wind speed in kilometers per hour, multiply the number of complete rotations the colored cup makes in 30 second by the diameter (in centimeters) of the anemometer. Then divide this number by 265.
