Default Re: Science fair Ideas....

I remember in my fifth grade science fair what I did was I took apart an old 4 stroke Briggs&Stratton off a pressure washer and brought that in. Think I used a poster to show the four strokes, what each one did, and how the internals of the engine worked. My brother helped me out with it, but everyone at the fair thought it was so cool, and I learned how an engine worked.
