PHYSICS: Leaves gracefully falling – can you apply concepts from this chapter to explain? Practice, practice practice the problems, but don’t forget the conceptual stuff! How do parachutes work? What causes whiplash and how do seat belts work? If you get a chance, watch the Julius Sumner Miller videos on Newton’s 2nd law and 3rd law on You Tube.

Chemistry 11-8-23 Chemical Formulas with Polyatomic Ions

CHEMISTRY: Great start today with writing formulas with polyatomic ions! Watch out, there are a lot of letters and numbers to keep track of. So something absolutely necessary – you have got to memorize polyatomic ions – or better yet, learn them! And practice, practice, practice!!

HW UPDATE: The Common Substances Research is now due Monday in class. Chemical Formula Practice 4 due date is changed to Monday.
