Overall, you did a nice job fitting the data and extracting quantitative values from the images. You were maybe fighting the deadline for turning the lab in, so weren't able to think as deeply as you would have liked about the analysis as you would have liked. There are some pretty easy places where plugging in the correct numbers

(like the density of water) would have made a big difference in the results.

You don't have any references listed, that is a major omission. Surely the quotes you have in the introduction came from somewhere!
