Science Buddies: Weathering the Wind Chill
The Science Buddies site offers hundreds of ideas for science projects. This one is an experiment evaluating whether wind speed affects how quickly an object cools
. The procedure explains how to set up the test area, how to graph wind speed, and how to measure the effect of wind on how fast a cup of coffee will cool. There is a good explanation of what windchill factor means, especially in terms of how it affects your body and how fast frostbite can set in.
