CHEMISTRY: How about cranking it up a notch?! Great job today naming compounds with polyatomic ions. Something absolutely necessary – you have got to memorize polyatomic ions – or better yet, learn them! And practice, practice, practice!!
HON CHEMISTRY: So how many molecules of water do you think are in these drops? The little mole turns out to be a pretty big deal – and a very handy tool!!
Great job today! Here’s discussion on formula mass and molar mass, and then using molar mass and Avogadro’s number as a conversion factor. You’ve got a couple of great tools – so now think through the problems and go forth and conquer!! Be sure and practice them so you don’t forget!
PHYSICS: Boxes and block, all slipping and sliding… Is it starting to make a little more sense? Here’s our last overview of the test, another look at some concepts, and a last look at problems. Below the vodcast for today is the help session from this morning.
God bless you as you prepare for your test! Keep sledding and watch out for net forces!
