  1. Hello everyone, I have some problems with my geography IA. The research question of my fieldwork report is: Does the quality of public transport matter on the amount of traffic jams in the downtown of Szczecin? I colected the data by preparing a questionnaire, in which, first of all, I asked people about their sex, age group, place of living, number of people at home. Then I went into frequency of usage of public transportation, their most frequently used mean of transport (private car, bus, tram), assessment of public transport, its pros and cons, proposals of changes (all questions are close
  2. Chronicle of The Death Foretold! Women! I wrote WA concerning these two things but as it was said I had to narrow it very much. And my conclusion is: it's going to be your misery. WA in "Laguage A: Literature", even "Language A: Literature" in itself is very difficult and strenuous thing. For a scientific mind (like me0 it is a(n) (un)necessary evil. It is even more sad if you know that there is an easier course for studying mother tongue, called "Laguage A: Literature and Language" (check in Lit.&Lang. subforum what's the difference between these two), but such curriculum for your tongue
  3. Hello everyone! I have problem with my Design project in IB Chemistry HL. My research question is: how does the concentration affect the value of experimentally determined enthalpy? I have collected the necessary data, I've created a graph of temperature change versus concentration - it shown the positive linear correlation. After that I have plotted the graph of enthalpy change versus number of moles. As we know, enthalpy is amount of heat changed per mole of a substance. It does not change with the number of moles, it is a constant. Thus, the graph should look in the form y=c, where c=const.
  4. I have a question concerning my lab report. i do not know where shall I indicate that sth is used as a constant, and the value of that constant. Now I am writing a Lab Report concerning determination of power of the kettle. The gradient of my graph is equal to m=P*c^-1*m^-1, where "P" is power, "m" is mass, and "c" is specific heat capacity. "c" is used as a constant in my calculations. It is worth noticing, that I do not need to use that constant in collecting, processing, and presenting the data (table with independent variables with corresponding dependent vars). I use constant only in calc
  5. Oh I have forgotten to add that I will prepare samples with different molar concentrations, but all of them will have the volume of 50 cm^3. Could you elaborate on why things will go wrong if mass of water changes? Comment on temperature change: it should not be a controlled variable as it will change as a result of using sample with different molar concentration.
  6. Hey guys! during the upcoming week I will conduct my Design experiment. We start on tomorrow on Monday. I have chosen topic connected with energetics and enthalpy change. i am investigating one factor that affects the experimentally determined enthalpy - in this case it is concentration of one of reactants. I've sent the Design recipe to my teacher a week ago, today she gave me a feedback in which she suggested slightly changing the title and some sentences. In general, she said I know what to do and how to conduct an experiment. But my biggest problem is with the equation and identifying the
  7. @sof****, you are now in pre-IB and you take exams in May 2014, while i'm in IB1 and take them in the same year ? O_o. I think you should recheck your exam date Anyway, my set is: Maths HL Chemistry HL Physics HL English B HL Geography SL Polish A1 SL and... if you are really curious about the boundaries of human stamina, this is the set for you Math HL - I heard a theory that getting 100% from exam is not technically possible, you don't have even that much time. Do manage your time well, when you read the qeustion you should already know the technique of obtaining an answer, even know an an
  8. In this experiment I am supposed to count the concetration of vitamin C in tested sample. Vitamin C (ascorbic acid) has the formula C6H8O6, and can be oxidized to dehydroascorbic acid C6H6O6, using iodine. Oxidizer comes from potassium iodate and potassium iodide, which react with each other in presence of hydrochloric acid. KIO3 + 5KI +6HCl → 3I2 + 3H2O + 6KCl Iodine reacts with ascorbic acid as shown below: C6H8O6 + I2 → 2HI + C6H6O6 Due to this reaction, formed iodine is immediately reduced to iodide as long there is any ascorbic acid present. When ascorbic acid has ran out, the remai
  9. No, no. I agree with the sentence. In fact, the headmistess convinced me that what I've done was a collusion. I like her explanation and I know that every expert in IB will state the same about my act. But anyway thx for an offer.
  10. I was wrong, my chemistry teacher was connoisseur in my case. She said that, yeah, I was unlucky. Because I wanted to help somebody, and this person had unclear intentions. What's more, as I sent him the digital version of lab it may be interpreted as a collusion, despite the facts (written above). A day after she gave an opinion I was posted to the headmaster. She wanted me to clearly describe what happened. After giving my testimony, I asked if it was a collusion. Yeah, it was, again, in spite of the facts. Why? Because while you send your work via internet, you actually get get rid of your
  11. Thx for all your replies. After few days i actually know nothing. I wasn't interrogated yet (and I am not sure if I would ever be). My colleague gave me some information: -as the work was not intended to be sent for moderation, the results of such plagiarism are negligible -court of justice is rather going to rely on in-school constitution (there is nothing about drop-out or post in the student's briefcase), not the IB (but I still don't know if the court has been introduced to the case) -I should not worry about myself
  12. My social life is in school and during CAS. On CAS I do sport dance, so I spend not 1 hour a week on Action, but about 5 or sometimes even more (but on CAS I only count one). I don't party hard, because i don't like parties where alcohol is a catalyzer (=without it fun doesn't take place). The second thing is that I like dancing but only strict dancing (that's why I've chosen sport dance). I just don't like "club dancing". So, as you can see, I am not bookworm, I have some free time, which I spend mainly on dancing to prepare for tournaments, and to have fun.
  13. Hello everyone! I will clearly describe my case. There are two people involved: me and my colleague. I attend Physics HL, my colleague attends SL. We are tutored by two different teachers. I was given a task to investigate Hooke' law, and write a Lab Report from that experiment. This was my very first LR. Deadline: two weeks after conduction of research. I wrote a work and gave it to submission. SL group had the same task, but given later. My work was already checked before the deadline of SL. My Lab Report was the best in the group. After "moderation" I started boasting myself: "F*** yeah, 14
  14. My university requires 2 experimental sciences HL so I had to choose. Chemistry was a must - I love it, because it is really logical science for me. Then I had to distinguish Bio or PhysX, both on HL (I am not a masochist to take all three experimentals). I know I am able to learn Bio well, but it would take a looot of effort to get good grade. And PhysX is a description of the world by mathematical equations (take a look at my Math level, it corresponds to my love towards it). So the verdict was easy to predict.
