How does the height of a ramp effect the distance a marble travels?

We are now in our Force and Motion unit. We did an exploration where we tested to see if the height of a ramp would effect the distance a marble traveled. We made a ramp out of books and a ruler. Our first trial, the ramp was on 1 book, then 2 books, and then 3 books. We analyzed our data today and can make the statement that the higher the ramp, the farther the marble traveled.

We also discussed the force that was acting on the marble as it went down the ramp. Gravity was pulling the marble down.
