What's going on in class 4/1-4/10

IB Chemistry
Spring Break homework= May 2009 (timezone 2) exams paper 1 and paper 2.  You can find the tests and the markschemes on freeexampapers.com or posted on the class wikispace.

Environmental Chemistry!
You'll be learning about the Chemistry of global warming, acid rain, water treatment, ozone, and even waste dumps.  Yee-ha.  ESS students have a huge advantage, but will be looking at issues from a chem perspective only in this class.

Extra Credit: make a city on electrocity.co.nz and email it to me.  You just need to survive for 150 turns to get the credit.  I'll discuss how to play the game in class.  
My teacher code is: CB18603

Next up= review for the big test May 16 and 17.  
You will have your final exam in this course May7-10

Chemistry
Acid/Base unit is coming up.  
Ms Philips is in charge of the entire unit- planning and presentation.  So, stay tuned.

What's going on in class 3/4-3/18?

IB Chemistry
We're studying Food Chemistry right now- hydrogenating fats, antioxidants, preservatives, artificial and natural colors, and genetically modified foods.  By the end of the unit, you'll know how haggis is made, what the issues are with GMOs, and about some scary food additives.  You'll also be able to argue both for and against food preservation and describe some of the extreme food waste in North America.
Your final IA is due Friday 3/8.  If you're really wanting to improve your IB score, you can choose to do the optional one highlighted on the wikispace (see link below).

There is no test for this unit... just little quizzes: Groups/Fats, Shelf Life, and Terms.

Next up= Environmental Chemistry

Chemistry
Stoichiometry!  We're learning about how to convert amounts of 1 substance into amounts of another by using the balanced equation.  For example: If you have 0.9g of Mg and react it in air, what mass of MgO will you make?  Then, we'll be doing the same type of calculations but given two amounts.  For example: If you have 0.9g of Mg and 10L of O2, what mass of MgO will you make?  For this second one, you need to first figure out which reactant limits the amount of product/which will get used up.

Extra Credit WS on the wikispace (see link below): Stoichiometry 3
Plus, there are a few random worksheets available in the classroom, so you can take one and do it for an extra stamp on your packet.

Stoichiometry Test Monday 3/18!
