First off, if you are having trouble with any of the unit conversions problems, stand up and walk over to Mr. Button and grab a practice worksheet. Sit down and ask him questions or watch him do a couple of problems. He's real good at it.
Second, if you are confident about conversions, open the Power Point attached here and go through all the objectives. As you do that, you can work on the last assignment that will go into your folder, the Important Chemistry Terms for Unit 1. Stand up and go get a copy of that assignment. It's over by Mr. Button.
