Rolling Marble Lab

Will a marble roll further if I increase the slope? (angle of inclined plane) Problem - Hypothesis- I think if I increase the slope, the marble will roll __________. Materials - Marble, books, ruler, meter stick

Procedure: 1. Place a textbook down on the floor and lay the ruler so it rests on the floor and textbook like an inclined plane. 2. Roll the marble down the center of the ruler and record distance marble traveled. 3. Repeat twice more. 4. Place another textbook on the first and again place the ruler on the books. 5. Repeat steps 2 and 3.

Distance a Marble Travels as Slope Increases Angle of Slope Distance Marble Travels (cm) Trial 1 Trial 2 Trial 3 Average Less Slope Greater Slope

Conclusion- My hypothesis was (accepted/rejected). My hypothesis stated that the marble would roll (______) when I increased the the inclined plane. In the experiment, the marble rolled an average of (__) cm with a steeper slope compared to (__) with a smaller slope. I learned ________________________. Next time I would like to try _____________.
