Engaging in inquiry

During the guided inquiry activity I created an experiment to see if different types of surfaces would affect the momentum of marbles. The one aspect of this inquiry was determining whether the momentum would be different on the hardwood floor. I also used another surface; carpeted floor. I was surprise that the momentum of the marbles on the hardwood floor did not affect the momentum of either size marble. I would have to say this was the one aspect that might have affected my conclusion about whether the size of the marble would make a difference. If I made any modifications it would probably be with other types of surfaces to test. I would make this experiment more real life by using a skateboarder and changing the different types of surfaces to see if that would change their momentum. The one thing I would want students to learn from this experiment is Newton's Laws of motion and how friction would affect the momentum of an object.
