EXTRA CREDIT: READING GUIDE ANSWERS:
Somehow, either with your own computer or with the help of someone else if you don't have a computer of your own to use, get the answers for the chapter 8 reading guide worksheets from the "filled in" worksheets that I've posted on this website. Prove to me that you got the answers. Your proof can be a screenshot attached to an e-mail. Your proof could be a printout with your name, period, and date written on the top. (Only one page of one reading guide is required as proof -- no point wasting more paper than necessary on this.) Each person needs his own item of proof, either an e-mail that is just from you, or a printout page that has your name and only your name written on it. Other forms of proof might work as well. Show me on Monday.

Warm-Up: Tell me what happened while I was gone yesterday. What did the substitute do? What did the students do? What happened with my computer? Tell me at least one thing you learned from yesterday's activity.

NOTE: This warm-up was turned in as a written assignment, although it was not treated as a high-security test.

Hope your day with the substitute was peaceful, productive, and enlightening! If you have a friend or two who doesn't have Internet access, tell them to write me a note by hand that has "pixie dust bucket" in it, and they'll get just as much credit as if they'd e-mailed me.

EXTRA CREDIT:
Warm-Up "Honors Curve" Algebra Task:
On the 9/21/2012 Warm-up where you were asked to give electron configurations for three elements and an orbital diagram for a fourth element,
5/100 counted as 70% for grading purposes, and
95/100 counted as 110% for grading purposes.

Determine the y = mx + b equation for the relationship between raw score (x) and % for grading purposes (y). (I've given you the x & y values for two points on the line, so you should be able to calculate m and b from these.) Graph the equation. Plug your score on the warmup (x) into the equation to determine your % for grading purposes (y). Do this all on a sheet of notebook paper and turn it in for extra credit.

HINT:
x1 = 5 y1 = 70
x2 = 95 y2 = 110
