What happened this week?

This week felt oddly short for some, feel's like I didn't do much. Hmm, I don't seem to remember doing much at all for chem this week. Mostly review for the upcoming test. It is the end of the grading period though! We just did our retakes for the quiz I did horrible on...I'm sure I did much better this time. We also got to play with dry ice, which was pretty cool ( I got to take a piece with me and it took about two hours to completely disolve). Other than that though there's not much else that went on.
