Tell us about your team: Our team The Walruses, we are both sixth graders for Clarence Middle School in the 5-8 division.

3. Design Brief
Problem Statement (What is the problem that your teacher has given you to solve?):
we have to save fossil fuels and the only way to do that is to make wind turbines. The wind turbines create reusable energy which does not pollute. Wind never runs out and fossil fuels do.
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 solve this problem by making a wind turbine. We are going to design blades to create electricity from the wind. This will help the environment and the atmosphere
