I chose to investigate how different surfaces affect the momentum of marbles.  I choose different types of surfaces that I wanted to test.  I released the marble from a slanted book that was consistently the same slant.  I recorded the distance for each test in order to see how the surface affect the momentum. 

The experiment went smoothly for the most part.  The marble rolled further on smooth surfaces and not as far on rougher or bumpy surfaces.  The outcome was what I expected.

Some areas that I need to consider if I ever do this with a class are the different things that affect the momentum of the marble besides the surface.  Levelness of the floor, wind, and object in the was are a few challenges that I had during the experiment. 

I am not sure what modifications I would make to this experiment.  I think it would go well in a classroom.

I would set the investigation up very similar by having the marble, ramp, and a way to measure distance available to the students to problem solve.  I would probably try to have a larger variety of surfaces for students to choose from.  Some examples may be sand, oil to cover a surface with, and gravel. 

To connect the experiment with student real life, I would have them think about bowling or golf.  Students could have the problem of creating a new game played with marble.  They would need to choose a surface and explain why they choose that surface. 

I would like students to have a deeper understanding of momentum and how surfaces affect the momentum of objects.  This goal was achieved based on the data collected after the tests.
