  1. Past hour
  2. I really want to do an English extended essay and I need help finding a great book, hopefully one that I read, and there's the dystopian novel called Legend by Marie Lu and I want to know if that's appropriate enough before I ask my teacher and possibly get humiliated ?
  3. I admit, that's a very interesting topic Glad you found it fun! I was stuck researching artists (couldn't find a good topic so I just went with what I knew), as if I'm not doing enough of it in Visual Art HL... lol
  4. Today
  5. I did title two aswell! It was enjoyable c:
  6. Hello! At my school, they want us to begin to conjure ideas for our EE. Today I wen't to the library to check out my school's previous EEs and I was rather surprised by it. Although I had already heard that the science and maths EEs achieve much lower grades than the language and humanities ones, I was surprised to see almost all of the physics and maths EEs (these are my two strongest subjects) only getting Cs, Ds with the occasional B and E. This year, I happen to have an english teacher I absolutely love (although I'm not sure he's quite as good as my biased self sometimes makes him out to be). Regardless, I think he's great. I truly love poetry and so I have been thinking about doing my EE about two poems. The two poems I have in mind are two poems by William Blake. The problem is that so, so many people have compared these two poems and it's not a very original idea. I don't quite know if this matters as the librarian once said that 'you don't need to come up with anything yourself in your EE, just research other people's ideas and put them together'. I'm not really sure if this is true so I figured that I ought to ask you guys, the people of IB survival. Thank you xx
  7. So I'm in my second semester of my preparation year and I now have to decide what subjects I want. I want to study medicine so therefore I have decided to study both chem and bio HL, I still need to decide what group 3 subject I want and at what level. I can pick from history, phsycology and economics all at both SL and HL, which one would you recommend?
  8. Hi guys, I currently have a 6 from German B SL. My Paper 2's are usually moving around 20 to 22 points out of 25, so basically a 6, however my huge weakness is the Paper 1, which I sometimes even get a 4 on. I have a question. I cannot seem to understand how I can prepare or improve my skills in the Paper 1's, do you guys have any special techniques or any tips? My MYP German teacher was completely useless and I feel I am catching up everything in these two years. I am graduating soon, so any feedback would be appreacited. By the way, I have a lot of vocabulary papers, concerning Grammar as well. Thanks for your help, any feedback or help appreciated.
  9. the arts

    This is odd since a person in my class is doing nude drawings of people and I believe they are submitting them to be apart of their exhibition. These images even have full-on nudity, meaning breasts and genitals are visible. There should not be an issue with nudity if explicit consent is given, no matter the media. I think you should speak to your teacher about this, and if nothing changes, maybe contact the IBO. It seems unfair that we can do nude drawings, but nude photographs are not allowed. The stigma around nudity really angers me, because it is such a natural thing but people seem to be so uncomfortable with a little bit of skin. I believe what you teacher is doing is illegal, especially in Scandinavia. Actually, I even took a look at the Constitution, and if you look at §77, it clearly states that she is not allowed to. Lycka till!
  10. I am doing my IOP in a month or so, and we have read (and seen) the Great Gatsby as well as The Bell Jar and now we have to prepare an IOP. I really want to discuss the main character in the novel, Esther Greenwood, and her horrible, quite offensive and ablest portrayal in the 1979 movie and compare her characterization to the novel itself. The only problem I have is my teacher not giving me enough feedback. I was initially going to analyse Plath's anti-semitism but I was not allowed to do so and now I am unsure if my topic is good enough. I have a lot of good points already prepared but I still feel as if my topic is not "right". While my teacher is good at what they do, they tend to forget to explain and guide us, even if asked to, and I find myself very confused about what the IOP is supposed to be about. Is there anyone who could maybe give me some feedback or help me out?
  11. Made it to Maple IB.
  12. Hmm I see. The thing tht surprised me the most was that the trend was nearly linear. As I was decreasing the ethyl ethanoate concentration, Kc increased linearly with it.
  13. You can use mol ratio if you assume that NaOH only deprotonates ethanoic acid and HCl. But you can also use the pKa of ethanol to calculate the equilibrium constant between ethanol and NaOH so see how accurate that assumption is. For example if you were to discover that the ethanol - NaOH equilibrium is 3, then that would mean the assumption is invalid and the acid titrated minus HCl added accounts for both ethanoic acid, as well as some part of ethanol. If you look up the solubility of ethyl ethanoate in water, you would see that it is not very soluble. Clearly in an equilibrium, you would expect ethyl ethanoate to be present in a own layer.
  14. Vitamin C titration is a common idea. In addition to the usual titration where one should explain why does the titration work, you would also have to relate cooking time to possibly temperature of the vegetable, to explain why would vitamin C concentration decrease (decomposed? evaporated? loss in water?) and most importantly, work with concentrations on a level allowed by your apparatus (in a vitamin C titration of a citrus fruit, you would not worry about too little ascorbic acid, but there is much less of which in many vegetables). I think it's a creative idea in the right direction, but I think it may be too ambitious in the current form of the question.
  15. Thanks for the help. The amount of ethanol cannot be calculated easily from the experiment I performed, but is instead deduced through the mole ratio with ethanoic acid (1:1). I didnt observe two layers in the quilibrium solution as far as I can remember. I will discuss your suggestions with my teacher to see if I get anywhere. Again, thanks for the help
  16. First you should understand that sodium, on a nutrition label, is not the sodium element, but the sodium ion. Sodium element and water react quite harshly. Therefore there are counterions, or anions, also present in the solution, and you should determine if these counter-ions affect the conductivity (which I do not know the answer to). Moreover, I am not convinced that conductance, a physical property of a solution, alone is enough for a chemistry IA. All it seems, and forgive me if I misunderstood, is that you want to take salts, dissolve in water; I just don't think that's enough. Dissolving salts in water is not electrolysis. The idea of aiming to replicating some phenomenon (which is different from replicating some procedure) is ok, you don't technically need variables. However, you should review your chemistry knowledge and pick a topic of which you know very well conceptually.
  17. Though you have correctly identified that HCl is a catalysis, you should read on reactivity of carbonyl/carboxyl compounds to determine whether the introduction of -OH may have impacted the reaction (during the time you performed the titration). Consider the two products, ethanoic acid and ethanol. NaOH deprotonates ethanoic acid, I agree, but you should also calculate if it can significantly deprotonate ethanol? What would be the equilibrium constant be between ethanol and NaOH? My final remark is regarding your observations of the final solution. Is there a single layer of liquid or multiple layers? In organic chemistry there is the "liquid-liquid extraction" technique, commonly known as "work-up", where you can separate different layers of liquids, which may be useful for you if you did observe 2 layers.
  18. The equilibrium constant has been calculated correctly, this I have confirmed with my teacher. Acid (HCl) is used as a catalyst for the reaction as the reaction is extremely on its own (hydrolysis of ethyl ethanoate). Therefore a fixed volume of HCl is added to every trial. This means that when performing the titration at equilibrium I get the total acid which consists of HCl and ethanoic acid. TO find ethanoic acid, which is one of the equilibrium values I had to calculate and subtract the total amount of HCl from total acid. Regarding OH-, I am not sure if that could have had any effect.
  19. I want to clarify that I will try to ask questions to help you identify potential flaws (that I probably am not aware of) yourself. Is the equilibrium constant correctly calculated, accounting for all species in the equilibrium? If the equilibrium is between water and ethyl acetate, why is the amount of acid of interest? Would -OH in any way, react with ethyl acetate, or in some other means alter the equilibrium?
  20. i am doing to the first topic can someone help me how to go about my essay i am lost
  21. No one person can provide a summary for all Canadian schools. If we have confirmed that 1450/1600 is a fairly competitive score and that 24/42 is low, possibly below many minimum IB requirements, you can gather more information by looking through the USA & Canada sub-forum for a collection of many many users' input on their impression of the schools as well as admission requirements. Your friend should first identify specific programs (and/or majors) of interest, and the desired semester of entry. A lot of schools allow an application to be made by end of January / early February, allowing documentation to be completed at a late date, possibly March. For example Ontario (a province in Canada) universities can be applied from ouac.on.ca, from which I learned, by random, that McMasters Arts and Science program requires 3 in IB English and 3 in Math SL/HL. Your friend can go through the site, and similar sites, to learn about admission minimums of schools. IELTS or TOEFL were mentioned; they are not required for someone from a English-speaking school in a English-speaking country, whom of course is expected to ace either test. Considering that many Canadian universities are closing admissions within next two weeks, and that you have not made clear what major your friend is interested in, he should immediately narrow search with the major in mind and apply to 2 or 3 schools without a minimum total IB requirement. I do not believe that your friend has time to prepare for and take any additional SAT tests in time for September 2017 admissions in Canada. The fall back plan is to try his best (with or without retakes) to apply later with more carefully prepared applications not made in rush.
  22. The solutions were left alone for two weeks and should reach equlibrium already after 48 hours. I was measuring the total amount of acid in the titration using NaOH.
  23. He said he will look into it as it seems like an interesting school! The only problem is for our school, everyone including staff is on break until January 31, so it may not be possible to get all of the information to them by a finalized deadline without being a bit late for the Jan 31st deadline. Any other good Universities in Canada? Also thats a good point about the external testing, I'll let him know. Thanks again! sorry for being a bother aha
  24. I am doing an ia on the topic of finding the value of Pi and like the different methods of finding it and finding out the best method out of the ones used, like archimedes, and leibniz series.Im worried about how appropriate it is to do an ia on this, Im doing math sl btw. Thx in advance
  25. Sorry, have been caught up recently in a few shenanigans so this is sort of a late (1 day old) reply to an earlier post @ILoveJesus [UPDATE 1]: Formatting screwed over ugghhhhh. Updated my point relative to reflect current replies [UPDATE 2]: Alright I think the formatting mess is over now - phew! 1.You argue that the Bible is 'not essential to the Christian faith' and concede that it is not objective, yet you argue that objective morals are indicative of the Christian God. Without the Bible, the closest thing you have as evidence towards God, there is no way in which you can associate objective morals with the Christian God. It's wrong to punch someone if they don't deserve it, but so what? Since the Bible is insignificant, and merely a figment of human opinion, then so is God's recorded command that 'Love your neighbour as you do yourself' or 'Curse those who curse you'. Without the Bible, there is no frame of reference for you to associate objective morality, and you are thereby disconnecting objective morality from the 'Word' of the 'moral law giver'. [UPDATE 1]: My original argument is partially invalidated because you have stated you are not defending the Christian God. I gather that the capitalised 'G' in front of 'od' indicates that you are arguing for the existence of a general monotheistic religion? I apologise for making the assumption, but I've learnt growing up assuming that the capital referred to the Christian God. However, the general disconnection that I mentioned previously still stands: Objective morals --> Religious text --> Some God Generally speaking, by refuting the middle premise, you disconnect any association of objective morals with said God. 2.Definitional fallacy acknowledged, 3. Firstly, if you allow me to substitute a shortened definition of conscience in place of the word conscience, what you essentially said was: So according to your conclusion, objective morality, the idea that 'some things really are right' and 'really are wrong', exists because our 'conscience clearly tells us these thing'. By replacing conscience with its definition, you are evidently making a no true Scotsman fallacy, whereupon you justify a claim by appealing to the 'real' or 'true' form of something. This one is a special case because you are doing the opposite, you are justifying the 'true' form of wrong by appealing to its original form i.e. Some things are really wrong because we think they are wrong. Just because a form of 'wrong' exists (i.e. in our heads, in our consciences) does not justify the existence of a 'greater' or 'true form of wrong. At this point, you might retort, 'we don't think they are wrong, we know they are wrong because thinking induces human opinion, thereby disqualifying your argument against objective morality'. But how is it that we know something is wrong without thinking about it? Throughout this thread, your core fallacy is failing to give evidence for this, instead substituting evidence with synonyms e.g. I guess what I'm trying to get at is that you are begging the question (justifying your claim through synonyms and circumlocution) rather than providing direct evidence.
  26. Topic: How can you rank up in League of Legends by taking into consideration the factors that affect placement? Here is the proposal so far: https://docs.google.com/document/d/1oiaNvOULQ1B6Da1zgD6MVSNVsCn9SedF0M2199v0Ans/edit?usp=sharing This topic was suggested to me by my teacher when I had to give a list of my interests. She recommended doing it on League of Legends due to the various mathematical factors present within it. She explained that my goal was going to be moving up a full rank by understanding what comes into play to win games. My question to you is, which mathematical concepts that are covered in SL Math can I use in my IA? Also, if you think my Research Question could be better worded or altered please feel free to leave feedback. I have seen others do IAs related to League of Legends (ex. Wards and Supporting IA) and get decent to high marks so I know it's possible, I just need to know how to get started. Thanks!
  27. For my IA, I am trying to determine the conductance (ion flow) in different drinks such as distilled water, Gatorade, Powerade, coconut water, orange juice, Pedialyte, and a solution containing sodium chloride. I was planning on doing this by using a digital multimeter and measuring the resistance of the substance and then taking the inverse of it to get the conductance. I would determine whichever substance had the highest conductance and by doing so, would be able to find the substance with the most electrolytes. Growing up playing sports, I have always been told the importance of staying hydrated as well as replenishing electrolytes after vigorous exercise, and I was interested to see if sports drinks like Gatorade and Powerade were really the best substances for athletes to drink as these companies have claimed. I am worried that my "experiment" is too simplistic since I don't really have any variables. I was wondering if this was enough to do for the IA or if not, I was wondering if there is a way I could alter the experiment a little bit so that it would be more challenging. One idea I had was to take the ingredients of the different substances and "rebuild" the electrolytes found in them. For example, Gatorade contains 230 mg of sodium in 500 mL and 65 mg of potassium, and I was planning on creating a solution with the same concentration of sodium and another with the same concentration of potassium. Then I would add up the conductance of both substances and compare it to the original Gatorade. I have no idea if this would work or even if it makes sense. Thanks in advance, Jerry
