Updated Grades/SPARK Lecture/Chapter 3 Test

I have graded everything in my possession and have updated Edbox.  This will be your Quarter Grade unless you turn in late work or extra credit by 3:20 on Monday 11/7.  Check your grade over to make sure that it is accurate.  Every now and then you may have something graded that is not yet listed.  Make sure that you let me know this week if you find an inaccuracy. 

There is a SPARK lecture tomorrow at 3:45 (get there earlier if you really want to go!!).  Dr. Evan Clark, Director of the Sustainable Water, Energy & Environmental Technologies (SWEET) Lab at PSU will be speaking about "Technology in the Developing World:  Revolutions for Monitoring Success."  You need proof of attendance, and a 1-2 page summary of what the speaker talked about (not just notes) and your response to it.  This may be turned in by 3:20 pm on Wednesday to earn extra credit for 1st Quarter.

Finally, remember that we have a test on Chapter 3 tomorrow (Monday)!!  While it will not count for this quarter's grade, make sure that you go over the Review Sheet and/or go to the Physics Classroom (link on this website) to get help.
