The Heat is On!

Out of the four materials (tin foil, perforated plastic wrap, wax paper, and wood pulp tissue), the materials encouraged the use of tin foil and wood pulp tissue. I know this because these two materials retained the most heat resulting in a final temperature thirty minutes later at 47.9 and 42.4 degrees Celsius respectively. If I were to repeat the experiment, I would like to test additional materials such as styrofoam, cotton or A4 computer paper. Out of these additional materials, I think that styrofoam would be the best insulator because delivery or takeout is often put in styrofoam to keep it warm for longer periods of time. Although, styrofoam is absolutely horrible for the planet. To test something other than water I would like to test another liquid we often keep warm such as tea or milk. This would bring the experiment into the real world and be more relatable for students. I would also ask which liquid students often drink warm or want to test.  I would want students to le...

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 ...
