Kid Wind Design Challenge http://challenge.kidwind.org/online Designed By: Team Name: 5-8 Coaches Name: Mr. Sean Murray Email Address: SMurray@clarenceschools.org Clarence Middle School
Our Team Tell us about your team: We are a group of three 6th graders from Clarence middle school and we learned how to generate power using a windmill turbine. We are looking at other ways to create an alternative way to create energy by using windmills.
Design Brief Problem Statement (What is the problem that your teacher has given you to solve?): our problem is that we are burning too many fossil fuels to make electricity. Design Statement (How are you going to solve this problem? Include the process you are going to take to solve the given problem) : we solved the problem by making creating a windmill turbine to generate electricy.
