The graphs below, excerpted from The Science of Floating & Boating: Volume 3 from Schottenbauer Publishing, show the differences between floating in laboratory conditions and in a natural (outdoor) reservoir.
Discussion Questions
- What is the range of force on the bowl?
- In what direction is most of the motion? How this be determined?
- How many times does the bowl go up and down? If unsure, state an answer with margin of error (e.g., 10±2).
- What type of mathematical function is shown by the bowl: (a) linear, (b) parabolic, (c) sinusoidal.

- Why is there greater variation in force and acceleration in this graph, compared to the graph of the bowl in the laboratory?
- Write a few sentences comparing the graphs. Specifically, identify whether there is anything unusual or unexpected about these two graphs.
