1. KID WIND DESIGN CHALLENGE Team Name: THE NARWALLS Designed By: AIDEN MCCARTHY AND LAUREN KUBIAK 5-8 Coaches Name: Pamela Urbanek-Childs Email Address: PUrbanekChilds@clarenceschools.org Clarence Middle School http://challenge.kidwind.org/online

2. OUR TEAM Tell us about your team: Our team, THE NARWHALS are from Clarence Middle School in the 5-8 division. The narwhals are made up of one boy and one girl in 6 th grade. We started about 2 weeks ago but we had a few challenges because of 4 snow days!

3. DESIGN BRIEF Problem Statement (What is the problem that your teacher has given you to solve?): There isn’t enough natural energy to produce electricity for everyone, ex: coal, natural gas, and oil. Wind is always blowing so no one will go out of power if the wind is always blowing. Wind is one of the top sources of energy. So wind turbines are perfect, they capture the wind and turn it into energy. Design Statement (How are you going to solve this problem? Include the process you are going to take to solve the given problem) : To solve this problem we are going to build a wind turbine to produce energy. It doesn’t pollute the air, and it provide electricity for over 5 houses for one wind turbine.

4. DESIGN BRIEF Constraints (What you can and cannot do/use.):  Balsa wood- you cant make complicated blades, the width is only 3”, but it can bend  Cora plast-your blade can be any size, but it cant be bent  Cardboard-its light but weak, but its easy to cut  You cant use metal  Cant be longer than 10” Deliverables (What materials and items you need to solve this problem)
