  1. Hi! So, I have been thinking of possible Maths IA topics for quite a while and have just decided to do it on Vectors (because I'm relatively better at it?). I have heard that quite a few game developers utilise vectors during the game development process, and so it would be in my greatest interest to base my IA on vectors in video games. However, I'm not quite sure on how to go about writing this. I have a basic outline of the structure of my IA (start with 2D then advance to 3D), but I'm starting to worry that it may not be as good as a topic as I hoped it would be. Could someone tell me if this is a feasible topic? What should I do to maybe add more depth to this investigation? Thank you!
  2. Hey guys, can someone please let me know the format of the front page and the other content pages of Business Management HL IA? If possible, please show me an example of the BM IA format. Thank you!
  3. I've been generally panicking about things I've noticed in my IA (which has already been submitted ). I just noticed that I forgot to include an in-text citation for where I got my method from. I used Kjheldahl's method for analysing proteins, and while I gave credit to Johan Kjheldahl for making the method, I didn't state the source I found this information from in the body of text (it's in the works cited though). I also have several instances of using knowledge from the syllabus without citing it. Should I have cited my textbook? I need to put my mind at ease because I'm really worried it could be deemed academic malpractice. Does the severity of infringement decide the punishment? I didn't copy and paste anything, and I'm quite sure my turnitin percentage is quite low, so could the punishment be less severe? i.e I get a 0 for the IA, but can still be eligible for diploma. Sorry for the long post! I can feel my life shortening with every IB panic attack, so I tend to ramble.
  4. Hey! I am writing my first article for IA from Microeconomics. I know that I have to focus on this particular unit (not brining up other topic from our syllabus). I am not sure whether what I want to describe is clearly a micro-case. It's an article about imposition of minimum wage in Ontario, the potential effect of which would be job losses. As the topic is a microeconomic one, I'm not sure whether the solution that I aim to propose is (unemployment is a part of MACROeconomy in the syllabus). I was thinking about offering subsidies to firms to increase the production and therefore, the demand for workers? But I'm not sure. Thanks for your opinions

  6. Hey guys, I recently started planning out my chemistry SL IA. I was thinking of using different materials and analyzing how they affect the calorimeter. I was thinking of linking this to the thermodynamics module. I was thinking for example of using styrofoam cups, metal, plastic. Do you think this would be a viable analysis, as I'm wondering if there really is something to analyze here... thanks a lot, Cyril
  7. hey guys, is it a good idea for me to do the laplace transform for my Math HL IA? I'll base it on simple harmonic motion of bungee jumping, and I need your feedbacks whether this is a good topic or not. There will be some out of the syllabus stuff, but it involves integration by parts, algebra and some basic stuff. I'm displaying the concept in an amateur way. Thoughts?

  9. So, basically me and my coordinator as well as my principal aren't in the best of terms, i was retaking my IB2 year and they decided that I shouldn't retake any classes and as well as my finals. But I know that I can still retake my subjects. Since they didn't want me to do so they will not accept any Internals from me, even though the deadline the school has has yet not passed. Should I get in touch with the IBO or let it be? Subject in matter: psychology and economics
  10. Hey, I need to collect data of many students for my Maths IA and would be really glad if some people could quickly fill it out. It's completely anonymous and only takes around 1 minute to complete:)
  11. Hi! I am currently designing my Biology IA experiment to hopefully conduct this week. I am sure that I want to investigate the affect temperature has on blood pressure because I have my own electric blood pressure cuff. My dilemma is that there are many different ways I could study this relationship and all of my methodology ideas so far have been shot down by my teacher. I would really like to see some decent ideas that can help me better develop the ideas I already have. I know there are many risks I have to be aware of because I am using human subjects and that I also need to control the group of people I choose (gender, weight, etc.) These are what I have already asked my teacher about: -Having my friends over at my house for a few hours and I could change the temperature of my house slightly then test their blood pressures (just a time and control of subjects) -I could put the subjects in my car one at a time and change the A/C and heat of my car then record the temperature of the interior using a probe thermometer (my teacher had a concern of carbon monoxide poisoning even though I was going to do this outside anyway) I know there are so many factors that I would have to control like: what they ate that day, their exercise level, etc. It would be great if I could get eliminate the human subjects factor all together but with my topic that would be impossible. Any and all feedback on my ideas so far or possibly new ones would be greatly appreciated
  12. I am trying to do a Math HL calculus IA on the flute and my outline is due in two days. I started by measuring the distance to the first open hole for each note fingering and graphing it on the x axis with frequency of the notes on the y axis. This gave me a quadratic function that can be differentiated to find the change in frequency with respect to distance (df/dD). I was hoping the differentiation would be a bit complicated but it's just the power rule since I got a quadratic. I am now trying to use related rates to find another rate of change, but I can't think of one that would be relevant. I was thinking of doing something with the volume of air required in relation to the distance to the first hole: dV/dD = dV/df x df/dD However, this would be way too simple. The variables I could change include length of the tube, volume of air, embouchure size, air speed and lung capacity. If anyone can suggest a way to salvage this idea, I would appreciate it. If I can't find a way to make this work I will probably cry myself to sleep because it's the only semi-good idea I've had.
  13. Hi everyone! So I am currently having troubles with finding a topic for my Math IA I actually already have an idea and I also talked to my teacher but she said that I'd need more calculations because all I have right now is just data collection and some basic calculations like calculating mean etc. What I have right now is: I'll collect data from two restaurants (Number of customers from 11am-4pm) One of the restaurants offers buffet and the other one doesn't I can make graphs with the collected data then compare them If anyone has any ideas that can help me, feel free to do so Thanks
  14. Hello! So recently Hurricane Irma hit, and school has been canceled for over a week. I really need data to start my rough draft for my math studies IA, and I would be eternally grateful if you guys would help! Here is the link, and thank you for everything.
  15. Hi everyone, I'm sorry for bothering everyone, but I need help on this one. The only internal assessment I have left to would be the Biology IA, and I am terrible at Biology. Don't get me wrong. I love working in labs and giving my all est to get the best result. However, I am stuck on finding a research question that's osmosis related. If anyone could just give me a tip on how to find a research question related to Osmosis, I'd be very thankful. If not, that's okay as well. Kind regards, Amekara
  16. So I have this idea for my chemistry IA that I'm not sure of. I want to compare and contrast the effect of the different ratio between baking soda and acid vs. the amount of baking powder on the height the cake after baking. Baking powder is a mixture of baking soda and another acid that reacts when mixed with wet ingredient; it is used to make a cake "fluffy." I want to see if baking soda + acid will have the same effect as baking powder and how different amount of it will affect how much the cake rises. Possible variables: Independent- the ratio between baking soda and an acid + amount of baking powder (the total mass of baking powder and acid will be constant, and the mass of baking powder will change) Dependent- The height of the cake after baking Control: size of the mold, the amount of ingredients for the cake (flour, water, oil, etc.), baking temperature & time, amount of batter before baking, type of acid, type of baking powder, type of baking soda. The problem with this idea is that there are too many variables that can influence the result of the experiment. For example, how it is mixed, placement in the oven, spread of the batter etc. Will this be a good topic to do? Is there any way for me to control these variables? Or change some aspect of it to make it more controllable?
  17. My IB psych teacher just warned us not to write in first person POV on the IA, even when outlining our procedures. I was a little confused, seeing as the IAs for every other course seem to encourage the use of first person POV, and in this one I'm literally outlining my research and actions. Is it actually a no-go, or is it just my teacher's personal preference?
  18. Hey guys! I've been trying to work out a Maths IA and I have the idea of creating a dice/coin game and using binomial probability. But I can't seem to think of a game that would allow me to end with a good Internal Assessment. If anyone has any ideas of inspiration, I'd really appreciate it! Thanks
  19. hi guys, I really need your help! I was supposed to do my IA using a physical pendulum, but then my teacher and I realized that it's too complicated and now I have to do something else. Since I don't have much time, I wanted to do a "simple" experiment that doesn't require expensive material and a complex procedure. The areas I'm really interested in (personal engagement) would be guitars (so an experiment on standing waves maybe?) and global warming/renewable energy (but I don't know what kind of experiment I could carry out with this topic), but I appreciate any kind of suggestion. Also, as I understood, carrying out a traditional experiment is the best way to get a high mark, right? Is collecting data from an authoritative source and then analyzing it risky? I have to redo my IA experiment because
  20. I need help choosing my IA topic. Honestly I am really lost right now and I don't know what nd how to do it. I have seen some examples and ideas but some seem way too simple and some seem way too hard. I want to do something on probability, but I think it would be way too simple to just do a probability problem. So i need help. How or where can I get ideas? And how do I know how to perform them (?)
  21. I am doing a database biology IA and I have hypothesised that my two variables are dependent on each other and that there will a positive correlation. However, after doing a chi-squared test I had to accept the null hypothesis and therefore concluded that the variables are independent. My correlation coefficient value also supports this weak relationship as it is 0.2. Does this mean that my investigation is invalid?
  22. This guide comes from the website where step-by-step IA guide is published and IB experts help with IAs. This is a trial version only (and I received agreement to publish it) but still there are many very useful information. Choosing topic: It is very important to choose the right topic (and then research question) of the Internal Assessment. Students are advised to familiarize with the marking criteria at this stage since the topic can be considered as good when it allows student to easily gain the highest score. For example it must enable students to collect sufficient qualitative as well as quantitative data, to support conclusions by available bibliography etc. [...] Common mistake is choosing too broad or too narrow topic. If it is too broad you would not be able to discuss and justify a detailed conclusion and additionally lose evaluation points. If it too narrow you wouldn’t be able to collect a range of data (quantitative and qualitative) and you may lose analysis points or your assessment may be too short and instead you may discuss irrelevant data (whole analysis should aim at answering the research question). [...] Full version includes: - Choosing an excellent topic - step-by-step guide & checklist - Example topics of Internal Assessments which received the highest marks - Structure of the Internal Assessment - to save students' time, not to miss important details as well as useful tips to get all marking points from each section Personal engagement: In this section you should demonstrate that you are particularly interested in the topic you have chosen. It is the best to show why YOU are interested, not only that it is worthy of investigation. Common mistake is to show personal engagement solely in the introduction. There are certain points where personal engagement should be shown to gain all the marks. [...] More important aspects: - how to show personal engagement - section in which you show personal engagement - how much focus should be put on that to gain all points Exploration: Regardless the topic of the Internal Assessment, the moderators search for certain aspects in the exploration. For example, the full list of variables affecting the investigation must be considered. They can be divided into: - dependent [...] - independent [...] - controlled [...] - uncontrolled [...] It is a good idea to put them into a table. [...] Choose the variables from the following list of variables and write them in the assessment: [...] Analysis: Uncertainties should be considered at each stage of the Internal Assessment. For example, if your balance has an accuracy [±0.01kg] your answers numerical values concerning weight should be given in the following way: 1.30±0.01kg. Common mistakes include: - 1.30 kg (without the uncertainty) - 1.3±0.01kg (lack of ‘0’) It is recommended to use dots (‘.’) instead of commas (‘,’). Check if it is correct on your graphs. [...] At the very end use them to show the total uncertainty of obtained results using following formula: [...] Evaluation: Evaluation should discuss strengths as well as weaknesses of the Internal Assessment. Common mistake is omitting strengths. Another error is not considering all of the vital weakness of the investigation or lack of sufficient development of students’ ideas. Excellent evaluations should focus on both systematic and random errors. [...] Additionally areas for improvement should be described and justified according to the strict principle [...] Make use of the following list of errors (already divided into systematic and random) [...] Literature Conclusion and evaluation should be supported by literature. [...] Some students write bibliography/footnotes on their own whereas there are programs which can create it according to the quoting style recommended by IB [...] More important aspects: - how to find bibliography? - what literature is relevant? - how many sources you should use to receive the highest grade? - footnotes and bibliography – requirements
  23. I am currently doing my Biology IA. I calculated the Mitotic index of six onion root tips for five different areas from top to bottom: root cap, mitotiz zone, elongation zone, and maturation zone. Now, I want to use a statistical test to show that there is a general significant difference between the five groups' mitotic index. I decided that an ANOVA (One-way analysis of variance) test will be approriate because it calculates differences between more than 2 groups of data. However, I don't know if IB will allow me to use this test because i heard IB may have restrictions on what kind of statistical test students can use. Does anyone know if such rule exist? If it does exist, then what other statistical tests maybe approriate for my IA? Thank you
  24. Hi! which do you think I should explore? May Days Barcelona, homage to catelonia, in 1937 Why did USA/UK/others turn blind eye to german & Italian foreign intervention any advice? Thanks

    So I chose to make my physics IA on fluid damping. The whole experiment is basically a mass on an oscillating spring and how it damps into a beaker with a different concentrations of sugar water solutions. my teacher want me to find a way to detect the amplitude of the oscillating spring. The whole experiment in the end is supposed to give me an exponentially decaying graph. Any idea on how I can somehow detect the amplitude. This is the website I found my experiment in if you dont get it. Its "Idea 8". PLease HELP MEEEEEE:
