#teamnosleep Posted May 15, 2016 Report Share Posted May 15, 2016 Hi guys, I know we have had separate discussion rooms for Chemistry, but I thought we can talk about Paper 3 specifically here :). How's everyone Paper 3? Reply Link to post Share on other sites More sharing options...
Alex98 Posted May 15, 2016 Report Share Posted May 15, 2016 (edited) I am higher level, I did Option B, and personally found it quite easy! I didnt sleep the night before just to make sure I knew everything. Though I did find difficulty in answering the question about Thomas' method or something about how to set up the experiment and ensure the reaction mechanism is right.

JamVaun Posted May 15, 2016 Report Share Posted May 15, 2016 I did SL chem, option B. I found section B really quite nice, but found Section A Q2 weird and I probably lost quite a few marks there... Reply Link to post Share on other sites More sharing options...
Seung Hun Han Posted May 16, 2016 Report Share Posted May 16, 2016 There is no topic session for HL, so I am writing here. So section A was straightforward although the second question "how to make 1.00dm^3 of sodium hydroxide carefully" question was just confusing. It was only two marks, so I think people wouldn't have found much trouble in section A. I did option B biochem. Whereas paper 3 seemed really tough in speciment with all the really specific details, I think this paper 3 generally focused on the big things like enzymes, hemoglobin. A big disappointed in the fact that they've allocated four marks on writing advantages and disadvantages of biodegradable plastics, but paper 3 was nice.

Well said sir. I've used the pearson and oxford book to supplement my knowledge on the option. As far as I know, there are only one advantage and disadvantage mentioned through out those two books. I thought they would probably bring up bioaccumulation and biomagnification but that didn't happen so... Reply Link to post Share on other sites More sharing options...
JamVaun Posted May 16, 2016 Report Share Posted May 16, 2016 For that question I put: Pros- less carbon footprint, easier to break down with the use of enzymes Against- Using land to harvest crops for plastic instead of food, Inability to recycle plastics Reply Link to post Share on other sites More sharing options...
