PHYSICS: So why is the first hill of a roller coaster always the highest? Here’s the lecture from Tuesday on the conservation of energy. Great job on the concepts and problems today – let’s put it to practice tomorrow, and even this weekend on that take-home lab. (Speaking of which – do you need a bead?)
Homework tonight is changed a bit: Pg. 179 – 184: 26 – 34 AND 39 – 43; tomorrow add the rest, 46 – 49, 51 to the review worksheet.
Hey, if you were to design a roller coaster, what would it look like?!? Don’t forget to print & read the Roller Coaster Lab

CHEMISTRY: Good luck studying for your test! Do you need any extra practice? Help session tomorrow morning at 7:15ish. I’ll post the lesson from today on Dalton’s Atomic theory in a bit – after you’ve taken the test tomorrow and Thursday. Holler if I forget!
Have you checked out the study suggestion sheet on Edline? Chapter 7 Stuff to Know & Know How to Do
Tomorrow’s test will be mostly multiple choice on memorization, application of concepts like finding oxidation numbers, short mole problems, all the polymer stuff, and lots of chemical formulas to write and name. Thursday’s test will be mostly the larger problems – like bigger mole problems, percent composition, finding empirical formulas and molecular formulas from scratch. BUT – be prepared for some of everything on each part!
Worst thing you can do? Just read over your notes – even if you do it a million times. Best thing to do? Practice! Take your notes and make practice test questions with different colored highlighters. Practice the memorization by making quizzes for yourself, flashcards, and quizlet.com. Practice writing and naming chemical formulas, practice working the mole problems, practice percent composition problems, and practice empirical formula and molecular formula problems! God bless you as you study – I’ll be praying for you!
