As part of their yearlong study of energy sources, fourth grade scientists at Will Rogers participated in a wind turbine design challenge! After learning about how wind turbines work, students used KidWind wind turbine kits and worked in teams of 4 to design wind turbine blades that would produce the most electricity, as measured by a multimeter. Once students completed their blade design, they tested it on the KidWind wind turbine, with a fan simulating the wind. Students recorded their results in their lab workbooks, and had to work as team to discuss design changes. The winning team was able to produce 270 millivolts of electricity! This lab experience was part of their yearlong Environmental Science theme project, which is all about evaluating energy sources.
