When materials are added to the surface of a ramp, which material will cause the OREO to roll the furthest?

Materials: 1 board 3 books (1 inch?) Take the books and put them in a pile, then place board so it looks like a ramp and is a ramp. ScienceNetLinks ( http://www.sciencenetlinks.com/lessons.cfm?DocID=21 ) This helps me understand my project more because it tells me how to build a ramp. No other website that I could find had how to build a ramp! I needed to know how to build a ramp because I did not know how to and the OREOs need to go down a ramp. ||  ·   sand  ·   soap  ·   ruler  ·   3 boards  ·   9 books  ·   recording sheet  ·   3 OREOs  ||

 * Hypothesis || I think that the water will make the OREO go the farthest because, like tires it might pick up speed and go further.  ||
