    WORLD LIT length

    Okay I have cut down to 1500 so words so no matter now - works cited, the question, coversheet and footnotes would surely not count to the limit, right?
  2. I've heard that the world limit is flexible - that you can write up to 1650 words and you will not be penalised. Is this accurate?
  3. I think that I have worked out this investigation in general, although there a few things that worry me: *for the first question about factorisation - is there any in depth explanation required, should i look at rational roots (as opposed to just natural roots), should i look for patterns in the factorisations, even if i don't think they are related to any other part of the investigation, and do these factorised forms have any real relevance, except when deducing the divisibilty of the expression for x=2,3,5... is this the only purpose of this question?! *When exploring more cases in question 1, should the main focus just be supporting what is shown through the divisibility of the expression for x=2,3,4,5, or are they look for some specific othere cases here? *I'd also like to check my assumption that generating a spreadsheet of results for the expression using excel is sufficient for the "appropriate technology" clause *When question 2 and 3 ask for refining and reconsideration of the conjecture, is this really necessary? In my opinion, although these steps simplify the process of porving the original conjecture, they don't really put any doubt in my mind about the conjecture made clear from the results of question 1. Am i missing something, or is this what everything else found as well? *I was also wondering whether people thought that question 4 was very short.. like there appears to be nothing much at all to write if one sticks strictly to the question.. should i actualy prove it, or disprove it, or is there really no need...? Ta
  4. I have just done a practical on the affects on equilibrium of various factors. We were given background information about two equilibriums (chromate-dichromate equilibrium and the equilibrium between [Co(H2O)6]2+ and [COCL4]2-) and given Le Chatelier's Principle, and then told to identify the factors that affect the equilibrium and evaluate wheter the equilibrium adhered to Le Chatelier's principle. Considering this is all we were given, the prac I carried out involved adding acids and bases to the first equilibrium and recording the direction (left or right) in which the reaction shifted (I also tried to vary temperature to seee its effect, but there was none forthcoming - is the chromate-dichromate reaction thermoneutral (or just about), or was there something else going on here...?) and then for the cobalt reaction i added HCl and water to shift the equilibrium, and again tried varying temperature this tiem with greater success. Which sections of the 2009 IA criteria would this practical be suitable for? Design and CE/Design/CE/All/none?

    I've been considering taken up an EE in English A1 on a Terry Pratchett novel (or more likely on one of several of the recurring characters), although generally the literature essay's I've heard people write on have been on more classic novel's, do you think any topic on a sci-fi writer (even one as sophisticated and clever as Pratchett) would immediately be smashed by the IB in terms of marking?
  6. In the intervening time ask your teacher, they are likely to have samples - and the general process is to discuss a specific piece of economic theory in relation to the extract. Try to pick articles which don't have much economic analysis in them (or at least if there is analysis it is in layman's terms) so that it doesn't seem like your just restating the article. Also make sure to define define define and use as many diagrams as possible- or maybe it's just my teacher who gets any about such things.
  7. It's not really about originality- it's simply about coming up with a question within the designated topic that allows for effective investigation. I don't think they intend that you come up with completely new ideas, but use old ideas and techniques(from wherever you might research them) and figure out how to apply them to the specific topic you are prescribed to investigate. Usually there are pretty clear approaches to take that you will learn simply from the course: for instance, a prac investigating equlibrium would involve varying one of pressure, temperature, concentration and evaluating the effect. A prac on rate of reaction would involve finding an easily measurable specific physical quantity from one of the reactants or products - such as colour of solution changed by one of the products. I don't think the design section is meant to be that daunting, it is simply an excercise in identifying a suitable approach (usually not to dificult to see), and then within that identifying the right variabes. Assuming that you've done 4 years of science with countless practicals beforehand, as well as the relevant theory for the specific topics you'll be investigating, it should not be a superbly challenging task.

    Topic 4 IA

    Hey, I'm just wondering, do the IB penalise you for flooding them with information, and also, if your practical is aimed at finding out something which isn't the dependent variable, does your research question talk about the dependent variable, what you are trying to find, or both. Also, are any people (e.g. IB graduates) willing to mark/comment on people's work?
  9. What were the actual questions to this? Do you have the full sheet of questions, it would be easier to assist from there...

    Does anyone else do Latin B SL, and then Cicero Pro Caelio: there are some bits of this translation that I can do nothing more than fudge. UNfortunately, thre are no notes on many parts in Austin and Ciraolo, and Grant gets far from the Latin - does anyone have a word by word literal translation, even if they put it together themselves? I've only done 24 sections so far, and I think I am only doing 30 altogether, but I'd be happy to compare translations - not sure if mine gets too far from latin at points. Anyhow, any references on good word for word trans would be much appreciated.
  11. I varied the volume of Na2S2O3, but kept total volume the same to ensure depth didn't change. I measured time, and used the inversely proportional relationship between rate and time to find the rate from this. Thanks for your help.

    How many people in your Maths class?

    We have 10 HL, 6 methods SL, 5 studies SL
  13. Currently doing pracs that our teachers propose we submit to IBO, although they seem really simple to me - we did everything (D,DCP & CE) however the design seemed frigtheningly obvious for both, so just checking whether these topics and my subsequent research questions would be acceptable to submit to the IBO: PHYSICS Factors affecting resistance in a wire. - What affect does length of nichrome wire have on the resistance of this ohmic conductor in a closed circuit? CHEMISTRY Factors affecting rate of reaction - What affect does the concentration of sodium thiosulfate have on the rate of the reaction between aqueous sodium thiosulfate and aqueous hydrochloric acid at room temperature? (Is this too specific, all I varied was concentration of sodium thiosulfate) Also, I know that we have to be assessed twice on design, DCP and CE, but could we for the sake of these three criterions be assessed based solely on two pracs - or do we need 12, with each fulilling only one criterion (note: I am completing the exams in November 2009, in case Internal Assessment has changed recently)

    IB-UAI mark conversions 2009

    The UAI conversions have been steadily dropping, mainly because NSW wants to protects its crappy HSC from appearing weak in comparison to the IB (even if such an appearance would be fair). Nevertheless, the decreases have only been in very small increments - 38 is still just under 99 - I think it was 98.90 last year? So we're not getting ripped off too much... can't get 100.00 though, 45 is only 99.95...dirty!

    Extended Essay

    I have a couple of questions: 1) I've been considering taken up an EE in English A1 on a Terry Pratchett novel, although generally the literature essay's I've heard people write on have been on more classic novel's, do you think any topic on a sci-fi writer (even one as sophisticated and clever as Pratchett) would immediately be smashed by the IB in terms of marking? 2) In terms of producing an EE in English, what are the expectations for "original research" - if we simply use citations from books as well as individual thought, will this suffice? Or do we need to go and find people (scholars/those qualified in literature + interested in the specific topic) to comment on our ideas and claims, or state their own opinions, in order to fulful the original research requirement? I genuinely enjoy just about every subject I do, and so I think I'll base my EE subject choice on what will be easiest to practically implement. From talking to my teachers, (a) Being 'original' in physics and/or maths either requires being quite trivial, or undertaking very significant practical experimentation/investigation. What is more likely is that any topic that I may have significant interest in will be: beyond the scope of my current knowledge base or already significantly analysed (particularly the case in mathematics). (b) In terms of Chemistry, the smae problem of massive investigation component has been put forward, along with the significant possibility that such investigation will result in few answers. © Economics has actually seemed like an attractive option for me, in terms of an analysis of real firms and theoretical firms, although collecting sufficient first hand statistical data on firms feels like it may be challenging - and further I have a feeling such a topic would have been done often in the past, in which case, would this topic suffer due to a lack of originality? Either way, assuming the practicalities + my lack of orginality in economics knocks this topic out, and considering that I have to complete an EE in one of the subjects I do (do I, thought not, but teacher says otherwise - first year IB school, so he could just be responding conservatively), then the only subjects left are Latin and English: an EE in either most obviously presenting itself as a work analysing pieces of literature, with a little bit more of analysis of the mechanics for a Latin essay. Due to not being in love with Virgil, Ovid and the like, I have preference for carrying out my essay in English A1... Thanks to anyone who is willing to answer my probably obvious questions.
