Our Team Tell us about your team: Our team name is The Energy Owls. We attend Clarence Middle School and are in 6 grade. We are trying to solve an energy crisis together. We became partners by the luck of the draw that our teacher picked out.

Design Brief Problem Statement (What is the problem that your teacher has given you to solve?): We are trying to solve a worldwide energy crisis.

Design Statement (How are you going to solve this problem? Include the process you are going to take to solve the given problem) :We plan to solve this crisis by creating the most effective wind turbine. This turbine will produce the most energy with as little pollution as possible. I am creating my blades out of balsa wood and there will be three of them.
