This IS the complete homework

Previously, [This is not the complete homework; check back tomorrow.  Right now, Thursday night, I want you to take 3 eggs (per family) and cover them with cheap vinegar (white or cider, not balsamic...) This is to remove the calcium from the shells.  Let these sit, covered in vinegar, until the shells have dissolved; that is, a day or two.  I'll post more tomorrow morning.]
Now, for the rest of the story>>>

The Eggs-piriment:  http://ilovebacteria.com/eggosmosis.htm
This will take a few days, so start now and don't forget it.  Please note: you may not have a scale to weigh the eggs; you could measure the circumference instead.  Record your data.  This is basically  the same experiment in your lab books on page 85.

Read for Thursday: Chapter 7.3 textbook/study guide.

  1. I like this khan academy thing. Just watching the science video got me two Meteorite awards. Apparently this is insignificant in their program, but it was fun all the same.

  2. Though it doesn't relate to our science, Tebow article was definitely the best part :P
