  1. My teacher told me the biology ia has to involve the variables. i.e. the investigation must be about the effect of sth on sth. That doesn't sound right to me. Isn't it supposed to be an exploration related to ANYTHING we've covered in the course? I want to do an identification of lactobacilli in yogurt by DNA profiling. Is it possible that my teacher is mistaken? What about other restrictions on the choice of topic? DNA profiling tech is unavailable in my school lab. Is it ok to use more advanced equipment in outside labs? Or would it be considered beyond our level or even academically dishonest? Or, does it have to be a lab experiment at all? I heard about someone doing polygenic traits with computer simulations. Is that also acceptable? Could it be disadvantaged compared with a lab experiment and receive a lower score? P.S. How much time should I spend on my IA in all? I know the guide says 10 hrs but does it take longer in practice if I'm looking to achieve higher scores?
  2. This is a informative and detailed guiding document that give explanations and instructions for understanding and using descriptive statistics in Microsoft Excel. The file is divided into two parts - The first part explaining concepts and the second part giving instructions for how to use it in Excel. Note that this document only covers for: Quartiles Interquartile Range and Semi-Interquartile Range Outlier detection Standard deviation A description for the median will also be explained. As this file is aimed to help those who are doing their Psychology IA there is also a section about how to plot a column chart showing median/mean values with S.D/SIQR as error bars.
  3. Hello, Does anyone know what the word count for an ESS IA is and if there is any abstract required? Thank you very much
  4. I am not sure what I can do my chem ia but I was hoping to do something in relation to medicine if its possible. Do you guys have any ideas of something that I could do? I really need the help.

    Math IA Ideas

    Hey guys! I need some help finding some ideas to do for my Math IA. I take Math SL and I want to do something that correlates with medicine. Can you guys please help find something to do? I am very lost nad could really use the help.
  6. I want to do my IA on cantilevers using a wooden ruler (I know, overdone) but I'm having trouble formulating an actual question. I already know what variables I want to change, would my research topic just be something like, "the factors that effect the period of a cantilever" or something like that? Also, is there a way for me to make this appropriate for HL? Or if I want to do HL, should I do my IA on another topic entirely?
  7. Hi, guys. I am currently having a bit of trouble figuring out how to control oxygen concentration for the yeast and measure rate of respiration (based on carbon dioxide gas production) at the same time. If you have any ideas, please suggest how I could do this? I have never worked with oxygen before or tried adding a gas while measuring another. My biology teacher has told me that physically it may be difficult... But I feel like this is 10000x better than doing sucrose concentration. I have a few ideas such as isolating the yeast in a container with a specific oxygen concentration and having an aspirator/vacuum pump come out of it somehow for the carbon dioxide to be captured but I'm not sure how practical this is. In addition to that, how do I go about finding 'the best' oxygen concentrations for yeast? Do I just find the minimum oxygen concentration needed and then use values significantly higher/lower than that? I've researched that there's a point where that respiration will stop occurring in yeast if the oxygen concentration is too high. I was just wondering how I could go about finding this range/value. In addition to the above point, if this seems too difficult/impractical should I change my dependent variable? Should I measure the rate of respiration by the presence of another variable? Thanks, imperialbee
  8. Hi, I was wondering whether I could use business tools in my SL Business IA that aren't in the Business Management syllabus for SL as well as HL. If necessary, the tool I intend to use is Porter's Five Forces Analysis. I do SL Business Management. Thanks :)
  9. Hi, I'm doing my ia on the topic of women's rights movements and women's suffrage movements, can you guys check my possible question? are they contentious, doable, good questions? · to what extent the war challenged gender roles and to what degree society accepted them (everywhere/America/France/UK/WW1) · to what extent do the suffragette campaigns explain why women were given the vote in 1918 (UK) I also have backup questions: · to what extent was the LON a success (in the 1920's) · to what extent did President Truman help African Americans which one would be best???? Thanks!!!!!!!
  10. Hello guys, I need an interesting bio hl topic for my IA. I was thinking about something connected with allelopathy, for example, planting mint and cucumber near each other and measuring how the cucumber is affected, maybe adding different temperatures so it wouldn't seem so easy? or something with essential oils and how they affect the growth of different plants but I don't really know which I could choose. What do you guys think?
  11. I really need more answers for my survey, my IA deadline is soon, I hope you can fill out my survey really quick!!! https://docs.google.com/forms/d/e/1FAIpQLSe7IuEph8ScgYcmxBfkcb0tid41fV1i1mycGQ-WJdw5q2s2Zw/viewform?usp=sf_link Thank you for your time!
  12. Hi everyone, I am currently planning for my IA and the RQ is about the effect depth of water on the road and weight of a car have on dynamic friction. Is this topic worth investigating (I of course don't know the answer to my RQ)? Or should I find a better real life situation to connect it to? Thanks a lot!
  13. This lab has been submitted and graded by IBO. It received a perfect score in all categories. Research Question: How does changing the angle of incidence of light affect the power output of a solar panel? Includes calculations, graphs, steps to linearize data, and a conclusion to an inconclusive lab. Good example for when you don't get your predicted results from the lab.

    History IA

    I have two questions for which I can't decide which one is the best one for my history IA, which one do you think is better or how can I make one better for my IA? What policies did Hitler enact in order to get total control over Germany? What effect did Nazi Germany have on public and civilian life?
  15. Hello everyone i need help on my biology ib my question is Does the diameter of hair change according to the hair dye colour utilised on it i have no idea what to do pls help thanks
  16. I need some more responses for my Math IA, so I would really appreciate if you would quickly fill out my survey: https://docs.google.com/forms/d/e/1FAIpQLSe7IuEph8ScgYcmxBfkcb0tid41fV1i1mycGQ-WJdw5q2s2Zw/viewform?usp=sf_link Thank you for your time!
  17. Hi guys, I'm about to submit my IA idea for math and I just want a few pieces of advice choosing one. Currently, I'm very much interested in cryptography and machine learning which are the topics that I want to do my Math IA on, are these viable ideas? Earlier when I talked to my teacher, he said that writing about the Global Positioning System (GPS) would be a great idea, but I'd much prefer the other two topics. What should I do to ensure that I get a high grade while doing something that I actually enjoy?
  18. I am writing my math studies IA and am super behind. My topic is on mortality rates in men and women between 1960 and 2010. If anyone could help me with running the data analysis using a chi-squared test I would be eternally grateful!! Thank you!!
  19. Hello, I have written my IA on complex numbers in which I included the "Phantom Graphs" and DeMoivre's theorem. We have had our first draft and my teacher told me what I thought she would, that a) the ideas don't connect and b) its not long enough. I have a couple weeks to complete it and I am panicking as I have no idea what to do with it now. I would like to add some information about the applications of hyperbolic functions of complex numbers and something about Euler's formula, but I don't know how to do it. I know I can't just write out proofs for all this as I might as well have copied that from a book. And so what do I do with the hyperbolic functions?
  20. I'm really confused about the personal engagement stuff that we need to prepare for the global politics IA, so could anyone provide some examples on what they did, or what I can do? I've been looking into human rights but am unsure how I can engage with the issue. Thanks!
  21. I am looking for a maths IA topic about calculus or series or trigonometry. It's better to have a problem that I could use multiple methods to approach... I am a little interested in origami and architecture now. And I was thinking about flexagons but cannot find any problems suitable for our syllabus...Can anyone help me?
  22. I have just finished my product for my ITGS IA. I am doing a DTP software using photoshop. However, my client gave me pictures that can be found in the internet. I absolutely have no idea about this. What should I do? Please help!
  23. How old can data for IA be? Is 2015 acceptable? I can't find it in criteria.
