  1. Hmm, I see. I don't quite understand what you mean with temperature though, would you mind elaborating and perhaps guiding me a bit towards how I should measure it? Thank you for the response by the way!
  2. Hello! I am an HL chemistry student who is looking for a relatively easy but interesting chemistry IA topic, and it seems like I found one - freezing point of depression of water. This topic has actually fascinated me for many years, so it will be quite interesting to investigate it. However, I am not sure how to proceed. First of all, I do not know which independent and dependent variables I should choose. Here is an approach I have been thinking of: Independent variable: the concentration of a certain salt (for example, NaCl) dissolved water. I can use 5 different concentrations of NaCl. Dependent variable: time taken for ice cubes to melt. Method: covering the top of an ice cube with the NaCl solution and measuring the time it takes for the ice cube to melt. Does this sound like a good idea, or is it too simple? Also, when melting the ice cubes, where should I keep them? Would it be okay to observe the melting process at room temperature, as in a classroom, or must I emulate cold conditions by for example making an ice bath? Basically, I would really really appreciate any help, feedback or guidance. I will seriously love you forever!
  3. Hello! So I have been brainstorming about what kind of experiment I could do for my biology IA for a couple of months now, and yesterday I had an eureka moment and figured out that I could do it about yeast. We brew a national Russian drink (kvass) at home and it hit me that we actually use yeast for that (I just never thought about it before). Since it's a biological process I could write an investigation about it, and the fact that yeast fermentation is something that my family deals with quite often and that it produces one of the most beloved drinks in my country, would make the investigation more personal and get me a better grade. So now I know that I want to do it about yeast fermentation, but I am having a big problem figuring out what to actually investigate. A thing I thought about was perhaps finding the optimum sugar concentration for fermentation, but it seems to me that it is a topic that has been overdone and is a bit too simplistic. So I wonder: is there anything else about yeast/yeast fermentation that is worthy of investigation and that doesn't require some advanced lab technique to carry out? Are there any other factors that I could manipulate that will influence the rate of fermentation, or the quality of the fermented drink, or the ethanol content, or the activity of the yeast? Some of the other factors (IVs) that I have thought about: Effect of different vitamins (Vitamin E, vitamin B, etc etc) on yeast activity. It sounds like the most interesting one out of everything else, but I am unsure about how long time it will take me to see any results (I don't want this experiment to be too long) Effect of pH on yeast activity Effect of temperature Effect of different types of sugars on yeast activity (glucose, fructose, sucrose?) Effect of oxygen availability on the rate yeast fermentation (this seems like an interesting one, but not sure how I could manipulate the oxygen supply) I found this on a website: "The presence of oxygen at normal atmospheric concentrations will inhibit any fermentation process. At very low concentrations, however, oxygen can actually increase the yield of ethanol. This is sometimes referred to as themicroaerobic effect. As the level of oxygen is increased beyond this point, byproducts such as glycerol and acetic acid (vinegar) are produced by the yeast in addition to ethanol, and the yield and purity of the ethanol are reduced. As I mentioned before, fermentation will stop altogether once oxygen concentrations become too high. This is sometimes referred to as the Pasteur effect." This seems like the other most interesting thing to investigate out of all the things I have mentioned above, and I don't think that I have seen that many IAs being done on this. But again, I have no idea how I can vary the level of oxygen, so if anybody has any idea I would be really happy Effect of ethanol concentrations on yeast activity So yeah, these are all the ideas that I have so far. Any other ideas, comments on my existing ideas, or pointers towards relevant research or interesting areas would be greatly, greatly appreciated. Sorry for the long post by the way!
  4. So, our teacher in psychology knows absolutely nothing about IB psychology and IAs, so this forum is my only chance of gaining some information! Anyways, here are some questions that I had about it: 1. For the experiment itself, how much are we allowed to copy? For example, we are replicating Bransford and Johnson (1972). There is a passage there about doing laundry, and we wondered if we could use the original passage that Bransford and Johnson used. Or must we absolutely create our own passage? 2. If somebody has any knowledge about that particular experiment, is okay if we use these two experimental groups: 1. context before passage, and 2. no context ? Is the "no context" group the same as a control group? I was a bit confused here. also, is it so that for our IAs, we only need 2 experimental groups? 3. Debriefing: does it have to be verbal, or is it possible for us to later send an email to the participants telling them about the nature, purpose, results & conclusions of the experiment? That's pretty much it I think, thanks in advance for any replies! Also, if you have any tips from your own experience with doing the psych IA, I would greatly appreciate if you would also write them here! For example, errors that we should avoid, things that you did wrong and that we should be wary about, etc.
  5. Like many others here, I am using a Mac (MacBook Air specifically, as it is very light and we have to bring our computers with us every day). I love love love it. I switched to a mac this year and I never want to switch back. It was very costly, but I think it's a nice investment and it makes my studying time/essay writing a much more pleasurable and smooth process!
  6. Basically, the question in the title. It would be cool to hear from you alumni/almost alumni, and might help those who are going into the IB or are doing it right now :')
  7. Yeah, I'm not the biggest fan of HM either, but thanks a lot for the suggestions! I'll definitely use them
  8. I'm sorry if there is thread about this already! But anyways, I'm currently making flashcards for psychology so that I can drill psych studies into my brain. Obviously, memorising all of the studies covered in the course would be a waste of time and energy, so I'm looking for those really central studies that cover more than one level of analysis/as many learning outcomes as possible (example: the case studies concerning HM). Do you guys have any suggestions of some really good studies that I can add to my list? Any suggestions would be greatly appreciated!
  9. I think what you're doing already is quite good! One thing I like to do for biology is create flashcards before every test (they always help me score max points and help engrave information into my brain). I hope that when the time comes for exams, I will be able to use the flashcards I make now as preparation. I am talking about digital flashcards by the way, e.g. quizlet, as I think that physical flashcards are a huge pain to make and also is a waste of time.
  10. Hi! So I've decided to write my EE in visual arts. We have around 2 more weeks to make preliminary research questions or at least decide on an area of study. I'm from Russia and I've always been very interested in the time period around WWII - Cold War and I've recently found out about how CIA used the works of artists like Pollock, Kline and de Kooning as propaganda/weapon against the Soviet Union during the Cold War. This spiked my interest greatly and I would love to write an extended essay about something that has to do with this. But I am not quite sure in what direction I should go and how I should formulate a research question. (Also at that time, during the 1950s, there was a movement in the Soviet Union called "socialist realism" which also served as propaganda as it showed communism in a very good light and depicted the perfect communist society. This movement seemed quite interesting to me as well) The ideas I've had so far are: "How was art used as propaganda for/against communism during the Cold War?" The problem I have with this one is: 1. The time period "Cold War" is too vague, so I was thinking of focusing on perhaps the 1950s 2. I am afraid that the essay with the question "how?" will become too narrative (is this correct? if so, what other word can I substitute it with?) "How/to what extent did art reflect the politics/ideologies of the US and the Soviet Union during the 1950s?" I feel like this option would be less narrative than the former, and allow me to focus more on the analysis of the artworks and the movements rather on actual politics. Something that I could do for an essay with a RQ like this would be e.g. taking 1-2 artworks from the US and 1-2 artworks from the Soviet Union that were created in that time period. I could analyse them and see how they "fit" the artistic movements I am focusing on (abstract expressionism in the US and socialist realism in the USSR). And of course, I could also talk about how these movements reflected the politics/ideologies of the US/USSR at that time: abstract expressionism = freedom/democracy, socialist realism = restriction/totalitarian regime. I am going to have the 1st meeting with my supervisor in around 2 weeks, but I'd love to hear opinions about all of this from you guys first. Should I continue brainstorming on this topic, or should I abandon it and go in a completely different direction? Which of the 2 "research questions" should I go for? Do you have any suggestions on how I could narrow the questions down further, or is the way they are right now more or less okay? Is an extended essay with such focus on politics a bad idea? Any input would be greatly appreciated!
  11. https://www.tine.no/oppskrifter/drikke/varme-drikker/hvit-sjokolademelk Ohhh this is a norwegian "recipe" for white chocolate milk!!! I'm so obsessed with white chocolate, so finding out that it was possible to make white chocolate milk made me crazy and also made me send this link to all of my fellow white chocolate fans
  12. First of all, don't worry - everything will be alright. I was in your position last year, and what I did is that I started to read the books for some of the subjects. We have a school library where we get the textbooks for all subjects, but we couldn't take the books with us over the summer, so I had to find them online. So throughout the entire summer I studied the books little by little (I personally focused on biology more than anything else). I took notes, watched youtube lessons about things I didn't understand, made flashcards etc. You obviously don't have to read all of the books before you start school, but going through at least some chapters in some of the subjects in such a stress-free time as the summer vacation will help you a GREAT deal. Also, since you have a lot of time on your hands now, I'd recommend you to try out new techniques for studying. You might have some techniques that have worked very well for you in the past, but since you have a lot of time now, I suggest you try something new and see how that works for you. Maybe you could find an amazing technique that will allow you to ace every single test in the future? That's what happened to me, but it can take some time to figure out. So use the time you have right now and not when you're in the middle of the IB! Looking around on the internet, or maybe on some of these studyblr blogs on tumblr, will give you many good suggestions Another smart thing to do would be to look through subject guides for all of your subjects. See what kind of assessments you will have to complete, what are the criteria, read some samples from other students, and maybe also ask the IB teachers/students in your school when all of these things will happen? This will help you mentally prepare and to envision all of the things in front of you and help you make a plan. For example, if you know when your school is starting to work with the extended essay, you can start thinking about your subject choices/potential areas of research very early on and therefore be 100% prepared. I started thinking about it in the summer and pretty much had everything figured out. Some of the people I know however, did not, and were quite stressed. If you do all of these things and continue to work well throughout the year, I guarantee you that at least the first year will be a breeze for you. But most importantly, rest well and enjoy your summer vacation! Good luck ☀️😊
  13. Hey! I am considering studying medicine as well, and my subject choices are HL chem & bio and SL psychology, which seems to be a good choice for most universities that I am thinking of applying to. Most unis in the UK require HL chemistry + either HL biology or physics for medicine, all other subjects are pretty much up to you (however I am not sure about the English B one, perhaps you could search around or email specific universities to see if they have anything against this). I am not thinking of applying for psychology, but all of my friends are, and they take SL biology & psychology (and no chemistry). BUT what you should choose depends on the psychology course. One awards you a Bachelor of Arts degree while another awards you a Bachelor of Science degree. If you consider applying for the latter (science), then I think you should at least have 2 HL sciences. But gahhh, don't trust me on this because I've researched this very briefly and cannot say anything for sure :(( But, from all of this I would say: definitely choose biology HL. If you want to get into medicine, choose chemistry HL as well, if you only have one of them in HL, it will limit your university choices considerably. I think I read somewhere that psychology as a subject is not even a requirement for most psychology courses, so I think that psychology SL would be more than enough. But as I said, you should not trust me on this and rather do your own research. Or even better, contact the universities directly and ask if your subject choices are alright. Good luck! :') summary: HL biology and chemistry + SL psychology seems like an okay choice for both medicine and psychology
  14. Hey, I was confused about the same thing before ahah. Basically - I think that it all depends on your CAS coordinator. I think that our coordinator would allow a group of 2 people, but yours might not? I have tried finding information about this on the internet but I have been unsuccessful so far Yes, I think so, but again it depends on your coordinator I think. Me and my buddies asked if we could run a blog and the coordinator seemed okay with that, but he said that we should rather make a youtube channel with videos about that sort of stuff instead of running a blog. We have decided to ditch that idea for now, and signed up to arrange the graduation day for the senior IB class instead Here it doesn't seem as there is a maximum amount of people that can participate. Our coordinator basically urged as many people in our class as possible to help with arranging the graduation, and our class is around 40+ people. So yeah, maybe talk with your coordinator to get the requirements that you need to complete the project? Because in the end, it is he/she who decides whether your CAS project is valid or not.
  15. Here in Norway, all public schools are free for everyone. However for the IB, we have to pay the exam fee (or whatever that is, I never actually checked what the money is used for), which is NOK 5 000 per semester, so 5 000 * 4 = NOK 20 000 after 2 years, which is around 2360 dollars. My mother is paying for it and we both agree that it is a reasonable sum. And how people get into the IB depends I guess :0 If you go to school in Norway, they accept you into the program based on the grades you got in tenth grade. The following info is perhaps specific to my school only: the IB here has limited spaces, but I think that the lowest points to get in was like 4.5 out 6.0, which is relatively easy (here in Norway, 6 is the maximum and they take the average of all the grades you got in all your subjects). But what's funny is that if you finished the MYP programme, or you apply to the school from another country, they don't seem require grades at all and accept you anyways (as long as they have proof that you know English and can handle math). But idk, it seems like IB is not that popular in Norway (at least in my city). Maybe because there's a rumour that it's a program for geniuses only/it's much harder than the normal norwegian program (which is not true) - so the competition is not as big.
