Clarence Middle School
Our Team
Tell us about your team: We are a team of three sixth graders from
Clarence Middle School. We are attempting to generate the most
electricity using our wind turbines. We turned mechanical energy
(wind) into electrical energy. The goal of this whole shebang is to
generate electricity without burning fossil fuels.
Design Brief
Problem Statement (What is the problem that your teacher has given you to solve?): The
problem is that we are burning to many fossil fuels which releases to many carbon dioxide.
(greenhouse gases) This is environmentally unfriendly.
Design Statement (How are you going to solve this problem? Include the process you are
going to take to solve the given problem) : We are going to design wind turbines to generate
electricity so we don’t have to burn as much fossil fuels.
Design Brief
Constraints (What you can and cannot
do/use.):
• No metal blades.
• Weight constraint.
• Foam core board, balsa wood,
Styrofoam, cardboard, etc…
• Length constraint
• 18-20 inches maximum length
• Dowels could be used.
• Width constraint.
• Originally no hot glue(that
changed)
Deliverables (What materials and items you
need to solve this problem)
• We had to create three different
drawings of our wings.
• We needed foam core board,
dowels, plastic hub, Kid Wind wind
towers, voltage meter, fans, tape
measure.
