Science where have you been

This is my first science class that I had in a long time. The trouble with it was last period period class rowdies of sophs that were last years bad freshman. They got into all kind of trouble. I tried something different with the assignment to. Not give the second assignment until everyone finished and handed in the first.Then judging on their behavior tell them the second (dvd). Unfortnuately some didn't hand it in until the very end and not everyone did it. So I withheld the dvd as well as not tell them. They aslo were misbehaving all through class with mp3 players, throwing things, and touching things they aren't suppose to. All were written down. I also realized that next year if the new fresh are bad  the seniors will be the only good classmen to sub for. Phoew! Friday my next day will be in-you got it in the new bldg and for Math but I'll have third period off with lunch. I'll have 2 hours off to relax and wait for that lousy last nothing period I expect will occur with the deadly trio of events we know all to well and loath as subs.
