Welcome Future Scientists and Engineers!

Do you ask yourself, 'Why' and 'How'? Do you like to take things apart to see how they work? Want to learn how to get the answers you seek?

By participating in the Ventura County Science Fair, you will learn the scientific and engineering processes used to answer the questions you have and solve the problems that you are interested in. Best of all, you get to choose the question or problem that you want to work on.

I invite you to become part of a program that will provide you with the tools and processes to look at the world in a completely different way. I invite you to have a lot of fun while learning something amazing about the world and yourself.
