“How does the steepness of a slope and mass affect a collision outcome?”

I used various heights and cars to see if it will affect a collision outcome. One the first try I used 1 book, then 2 books, and next 3 books. With each try I use the small marble to collide with the large marble then I used the large marble to collide with the smaller marble. There was not a different with the masses of the two objects but the height made a different where they rolled after they landed.  I expect when using 3 books, when the larger marble collided with the smaller marble it rolled a longer distance.

The experiment went well for the most part. Finding the right surface was the hardest part. The classroom floors were uneven so I decided to use the carpet instead.

The modifications I would make to this experiment, is releasing the marble from a different height on the ruler to get a different or modified result will be to specify what surface and type of cars to use.

I would use race tracks at different heights and cars with different masses. I will make it more like a race since most students are compative. I will time them to see which car crosses the finish line first.

I would like for my students to understand that force and motion is a part of our daily lives. I would like for them to have an understanding of the Newton’s three laws of motion.
