For quarter grades, don't stress, everything will just carry over to next quarter. That being said, check your grade, if you want to make it better by turning in some old work, bring it Thursday with a note stating what you want me to look at and leave it in the class turn in tub at the front of the room by the books.
There will not be any class time for finishing the rollercoaster or lab packets after break, so use the time wisely on Wednesday and Thursday - you can snap pictures of your coaster/whiteboard and email that and/or your spreadsheet to me if you would like some feedback. Please ensure that your whiteboard has the energy graphs colored in by the end of today, Wednesday.
