The quiz on Thursday, October 25th will focus on the following
areas. This is a guide that you should use as a springboard for thinking about
the concepts that we have been discussing and applying in Lab 37.
- Explain how the following demos relate to the topics at hand: hand flask, upside-down

- Know how to test something’s density by floating it.
- Why/WHEN do things float? What is buoyancy? Who was Archimedes
