A model will help you discover if your invention really works. In your Inventor's Journal you will need to make a list of supplies and tools you think will be necessary. You may want to consult with your teacher or parent when you get to this stage. They can help you make a chart in your Inventor's Journal to keep track of the information about materials and prices. You must have adult permission and supervision to use tools and work with electricity.
Safety glasses are essential.
Be sure to record in your Inventor's Journal any changes that you make as you build and test your invention. You might have noticed a patent number or a patent pending number. It protects your idea and gives you, the inventor, rights to the invention for 17 years. A patent gives you the right to prevent anyone else from making, using, or selling your invention without your permission. When a patent expires, anyone can produce the product without paying the inventor for it.
