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!
