Any team of 1-10 students (Grades 4-12) with an adult coach (parent, teacher) may enter the KidWind Challenge in an attempt to create the most efficient, functional, and innovative wind turbine.  Register for free.  Plan, build, and test your design. Then bring it to Challenge Day at UMass Lowell, April 30, 9AM-3PM to run it in the wind tunnel and compete for prizes and a chance to be invited to the nationals.
