What is the effect of large objects colliding with smaller objects?

 In the experiment, I was to collide large objects with smaller objects. The results were that the large object would force the smaller object to go in the reverse direction since they were traveling at the same speed. Of course, this was almost impossible to perfectly do as I wasn't using any scientific tools, but tried to make it relatively close to the same speed. 

These results were as I expected, but did not realize that it didn't take such a big difference in mass to witness a complete change in direction. This was good to verify, though.

The experiment went relatively well when I was able to get both objects to collide with one another and make direct impact. I'd say that was the biggest issue, which again is because I wasn't using any scientific tools other than my own arms to do the experiment.

To set up this experiment in the classroom and make it more engaging, I would try to have students roll the objects into one another with each student having control of one object. It wouldn't be interesting to have students watch another student have control of both objects.

To make this related to students' lives, I would ask them to design experiments and draw cartoons of them using this experiment in the real-world. I would also ask them, if they could, to think of how any jobs or adults might use this concept in their work.
