    Psychology help

    Hi what are some good resources to use for psychology hl, like which textbooks? Any particular website? Online Teachers ?
  2. Hi, I need to find ideas for my MATH SL IA and want to do Probability. My 2 ideas are either Probability in testing in medicine (false positives). Problem is I don't know what to do with the idea (what math to use) Normal distribution (any topic, just measuring distribution). If you could help me with ideas on any of the two as in what topics to include to get the highest grade I would be thankful. Is it enough to do a Chi squared test, normal distribution graph and use the equation? (for Normal distribution idea) Please I need urgent help and thanks
  3. Hey, I was really confused about how I should start my IA and about the research involved. Can someone please help me? My research question is "To what extent was Hitler's economic policies helpful in revitalizing the German economy from 1933 to 1941?". Thanks, Payas
  4. Hi everyone, I was wondering if I could get your opinion on whether this topic is appropriate for a Math Exploration in HL. I am planning on analyzing Poker Odds, mainly by focusing on Pot and Card Odds. I will certainly be using conditional probability, Bayes Theorem, Factorials, Permutations, etc. I will basically give an invented scenario and, from there, I will find the probabilities of having a certain hand and of winning based on the opponent calling or betting. I will also use probability to determine if the odds of the hand are profitable to continue playing. So, what do you guys think? Do you think this is a good topic and that the math used is appropriate for HL? If anyone has a recommendation on what I should investigate in the exploration, or on any changes I should make, feel free to tell me! Anyone who has done an exploration or IA on a similar topic, please comment too! Thank you!
  5. Hello everyone, it is urgent. I need to submit my biology lab report on next Monday, if someone is willing to correct it by giving me your Gmail account, it would be so helpful. The lab report is about the yeast respiration (2.8 Cell respiration). Could you please leave comments on my doc? I will share it with you. Thanks for your advance! Yours sincerely
  6. After welllll past 24 hours of brainstorming, I have nothing to show for it. Despite my ideas being somewhat creative and interesting, they are deemed unworthy by my holy chem teacher. It seems like no matter what I do I can't either measure or even investigate the topic. Cab anyone please help me?
  7. Hi, I am doing my extended essay in biology(obvisly from the title). My topic is related to plant and the effects of different concentrations of vitamins on the rate of growth of Solanum lycopersicum (tomatos). I said this to my techer and emailed her my RQ "How does vitamin C, B and multivitamin affect the rate of growth of Solanum lycopersicum?" She told me the topic is good, however the RQ is not developed enough. Can anyone please tell me what I need to add to fix my RQ???? Thanks in advance!!!!!
  8. Hello. I've been trying to find a topic and research question for my extended essay but I have been unable to do. I have found an experimental technique in the calorimeter which measures energy content/calories and I want to measure energy contents in different foods but I do not know what I should investigate specifically and expand on this. I don't want it to be as simple as "as x increases, y increases". Testing out different foods and seeing which one(s) have the higher calories is way too simple and I'm basically stuck..Please help!

    MATHS IA HELP - TIDAL WAVES?

    I have currently chosen to investigate tidal waves for my maths IA. However, I am unsure as to what other explorations I can do under this. (And whether or not this is too simple...) Is modelling and predicting future tidal waves appropriate? I have secondary sources that'll give me data of tides at different points in times at a beach, so I will be able to graph them. I will also use trig and algebra to find the ideal time to visit the beach with my "ideal" tidal height of 1.5 metres I am uncertain as to what other maths/exploration I can apply to this Any suggestions would be greatly appreciated!
  10. Hey, I have a question concerning the EE topics for English B HL, how can i approach a topic, keeping in mind the criteria that is given? This is really important for me, i'm struggling right now trying to find a topic! Can you give me any advice and examples? Thanks
  11. Hello. Recently I have had meetings with school administration regarding which IB subjects I want to select. I am certain of most of my subjects aside from Physics and Psychology. As it stands, my subjects are as follows: HL English Lang.Lit. HL History SL Maths SL French Ab initio I would like to do Physics and Psychology, one of course HL and the other SL. Choosing Pysch HL would allow me to achieve a higher score than doing HL Physics. On the other hand, selecting HL Physics would allow for a wider range of university/career choices. I am thinking of moving into a course studying Artificial Intelligence or something programming related. I have read through the syllabuses of both subjects and have consulted many teachers regarding their opinion. Is Physics HL really as challenging as several students on this site (and many others) say? Any suggestions and opinions are welcome. Thanks.
  12. Helloo there, I'm planning to do an EE on Eng A Lang and Lit and my tentative RQ is "How has the role and perception of women in Western 19th-20th century society changed through the lens of the appearance of women cigarette ads?" Is this specific/good enough? I'm also worried that my RQ is more suitable for an IA rather than an EE.
  13. I have chosen English Lit and Language A as my EE subject. I have come up with some topic ideas, but I want to see what you people think of these topics and RQ's: The effect that an epistolary format has on character development in Jerusalem's Lot and Frankenstein. Jerusalem's lot is a short story written by Stephen King. How does Agatha Christie’s use of literary techniques (red herrings, plot twists etc.) in And Then There Were None and The Murder of Roger Ackroyd mislead the readers about the plot? How does the usage of an unreliable narrator in Shutter Island and The Murder of Roger Ackroyd help create a feeling of suspense? Lack of knowledge as a consequence of censorship in Fahrenheit 451 and The Handmaid's Tale. Thank you!
  14. Want to share the title of your extended essay? Or perhaps need help choosing one? This is the place. Psychology - The Psychology of Road Rage: A discussion of psychological explanations of road rage and policy implications.
  15. Sooo I've been juggling a couple of ideas but my first was to analyse Avatar: The Last Airbender as a EE in Film. That was pretty quickly rejected because of the fact that writing an EE in a course that isn't offered in your school is just a really bad idea... I got really discouraged after something I was so excited to do was rejected flat out. Anyhow, I'm now writing my EE in Lang and Lit and analyzing ads. My research question is something along the lines of: To what extent are traditional gender roles projected in contemporary America through Super Bowl commercials? It has been approved, but I'm not incredibly excited for it, I mean it's cool but what can be cooler than ATLA, right? That's why I wanted to see if it would still be possible to analyze some global issue, even the representation of women, for example, in ATLA as a Lang and Lit EE. I mean, it's very similar to what I'm doing now, but something I'm much more excited about. I figured it'd be best to ask the IB community before pushing the idea further with my school. Any opinions/suggestions? TLDR: can I write an analysis of avatar: the last airbender for my Lang and Lit extended essay?
  16. I wanted to do something about veganism , but can't figure out a proper KQ for the topic , can someone give me some rough ideas for good KQ's?
  17. Hello everyone. I am writing my extended essay in history. I am interested in aviation (mostly after ww2) and also about the eastern bloc during the coldwar. Does somebody know of a topic that would fit those criteria? Plz Help
  18. Hi all! So basically, I had a topic ready for my EE, but then my teacher, who is also my EE mentor, decided that she wanted to put the book that I am researching for my EE as a free-choice for my English class, Little did I know, there is a new rule stating that we can't write EE's on books that we analyze in class, so now I have to change my topic and I need help. I was thinking of doing something on how eating disorders are portrayed in literature, and thus focusing on couple of literary works. Please, if you are a genius and now how to formulate EE questions, and/or know of a good book about eating disorders, please help me out. I will be forever grateful! I wish u all the luck (cause we're IB students and we need it).
  19. Hey! I have decided to do my extended essay in English Lang & Lit, i have decided my topic and the novel i'm gonna analyse. I was thinking of the novel Wuthering Heights by Emily Brontë, and i wanted to explore the topic of obsession and the way obsession is portrayed by the characters in the novel or the way the author incorporated obsession in the novel and its accuracy, considering the time this book was written. what do you guys think about the topic and the choice of this novel ? All help is useful ! 🙂
  20. Hello I'm a new DP 1 student and I started looking for ideas for my EE. I decided to pursue chemistry as my subject and I have a solid topic in mind, but it's not wide enough. I'm going to investigate differents cuts of meat of different ages and I'll compare the values of protein and fats in each. What can I do else? And how can I make this a proper topic? What experiments can I execute? If you're not allowed to help me, just tell me how I can find the experiment needed... Thank you in advance.
  21. Hey there! I was just wondering if anyone knows any good history resources to use. It's quite hard for me to memorize a lot so I'm very slow in comparison to my classmates because I like to take notes on the side of my book to get a better understanding. In my first history book (the move to global war), I was able to find sources on Youtube from a very good highschool professor who went through the book and explained the topics to his students and it helped me a lot. I can't seem to find similar videos for the rest of the books. Right now we're doing Authoritarian States (specifically Cuba and Germany). If anyone knows any places that could help me out i'd love to know. Thank you! Diane

  24. Hi! im wondering how to solve these projectile motion problems: A particle is launched horizontally with a speed of 8.0 m s−1 from a point 20 m above the ground. a Calculate the time when the particle lands on the ground. b Determine the speed of the particle 1.0 s after launch. c Find the angle between the velocity and the horizontal 1.0 s after launch. d Determine the velocity with which the particle hits the ground. A soccer ball is kicked so that it has a range of 30 m and reaches a maximum height of 12 m. Determine the initial velocity (magnitude and direction) of the ball
  25. Hi guys! For my IA, I'm investigating on the relationship between time fall a parachute to fall and its surface area, but I can't get a linear relationship. The parachute didn't reach the terminal velocity, so the velocity is changing when the A is changing and it's also accelerating downwards. What can I do? Help please!!!!!
