Tell us about your team: our team is called the bubblegum people. We are a team of 2 six graders named Ryan and Elise we are from Clarence middle school

3. Design Brief
Problem Statement (What is the problem that your teacher has given you to solve?): We are running out of fossil fuels or non-renewable sources such as oil and natural gas. The world needs to use more renewable sources so that the non-renewable sources will last longer.
Design Statement (How are you going to solve this problem? Include the process you are going to take to solve the given problem) :
we will solve this problem by building a Wind Turbine. Our cutting edge wind turbine will be top of the line and generate lots of electricity with it extraordinary blades.
