Now that you have a plan for your invention it is time for you to work on it. You will actually start working on your idea and answer the questions from your plan. This may be a step by step process so try different ways until something works. If it is a new process that you have come up with, describe the whole process as you go through it yourself so that others would be able to do the same thing themselves later. If you have invented something new explain how it works and how it will improve daily life. You want to keep testing your idea until it works.
Once you find a way that works you will need to ask for a Patent Application from your teacher, fill it out and have your principal and teacher sign it so it will be ready when you attend the Invention Convention.
