Our Team 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

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.

Design Brief Constraints (What you can and cannot do/use.):

• Coraplast • No metal• blades cant be larger

than 10 in• Blades should not be

wider than 5 in• No more than 4 blades• No less than 2 blades

Deliverables (What materials and items you need to solve this problem)

*a turbine hub*a turbine*a fan*wooden dowel

Constraint:weight

Constraint: strength

Constraint: Balsa wood

Constraint: cardboard
