The KidWind Challenge Vernier Kit has all of the hardware needed to measure the power output from a model wind turbine like students build for the KidWind Challenge.  With this hardware students will measure voltage and current across a resistor.  The software (not included) used with the hardware can then calculate the power in watts.

Vernier LabQuest
Vernier Anemometer probe
