1. Kid Wind Design Challenge Team Name : Crazy turbines Designed By: Jeffrey Greene and Erin Callahan 5-8 Coaches Name: Pamela Urbanek - Child's Email Address: PUrbanekChilds@clarenceschools.org Clarence Middle School http://challenge.kidwind.org/online

2. Design Brief Problem Statement (What is the problem that your teacher has given you to solve?): if the wind isn’t blowing, the wind turbine wont spin. It can also harm wildlife. They are ugly and loud. They can be dangerous. They need to be put together proffecianally. We need to make sure that the turbine is made just superstitiously. 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 use green electricity, and produce enough energy. Not as loud and look good in the process. The wind turbines will be properly designed. They will be well held together. Designing blades.

3. Our Team Tell us about your team: our team, The Crazy Turbines are from Clarence middle school. We are 6 th graders, and we have an awesome wind turbine. We have worked very hard to make this turbine. we used a cardboard box and produced a lot of energy with it. Technology inspired us to think of our crazy ideas and the flow of them. This turbine is our own unique ideas from tech. also the teachers inspired us to make this happen.
