In this lab, students will calculate the densities of soda cans (regular coke, diet coke, coke zero, sprite, etc.). And will be amazed that some sink and some float! They will determine why this is.
To conduct this lab you'll need various types of sodas in unopened cans, water, a scale, and giant graduated cylinders (or a fish tank, large beaker or modified 2L - I explain the modification in the teacher info section, don't worry).
I have provided a key for the conclusion questions. And some hopefully helpful information on set up, conducting the lab, and other random things.
