Winding Down

One more science video till Christmas!  But first, make sure all your papers are in order and everything up-to-date and finished/watched and packed away in your notebook -- don't lose those atom cards! Bring them Thursday, we will go over how to make predictions, as well as returning your tests.  Quite a few of you have not left a prediction in the comments, which was part of last week's homework, so do that.  And please leave your initials or first name so I know who you are.

And here is the link to the 30 minute video:

There will be homework after New Year's to prepare for the first class of the year.
