  1. Hi everyone. I am working with string-coupled pendulums, as I am dealing with the relationship of two pendulum, I am becoming increasingly frustrated that that I have not been able to linearize anything - they are sin/cos graphs and it's just so frustrating. Why are we required to produce linear graphs? Why can't I just compare the theoretical equation for the displacement of a pendulum, with the equation obtained from graphing my results? I could compare multiple aspects to get indicators of systematic errors, random errors are just the spread from the sine wave, and as for uncertainties, I can use trigonometric identities. I am so so frustrated. DO WE NEED LINEAR GRAPHS and will I lose marks from not producing one?
  2. Currently, my teacher has approved of my IA idea to investigate factors that affect the lift of a model airplane / helicopter. I can change any variable of my choice. However, as I looked into the topic I realised that I could not think of an appropriate method of testing. My original plan was to place the mode onto a scale ; for a helicopter to hover, the force exerted by the rotor blade on the air must be equal to the weight of the helicopter. (Newton's Third Law). However, in order to do that I have to spin the rotors and I'm not sure how I would approach a proper method to do so consistently. Any suggestions are greatly appreciated. Thanks!
  3. Does the SWOT analysis count in the word count? Let me know plz
  4. My topic is: To what extent was humanitarian intervention used to justify imperialist ambitions by the united states during the Spanish-American War? What part of it would I have to tweak? Is it too broad, or too narrow? I have a lot of research done on the Spanish-American War. I'm afriad that what I sit down and write it my question wil bring me issues or my research and sources will not help me at all. I'm just really nervous that there is still some tweaking to be done with my question, but I don't know what part of it to tweak. Any ideas?
  5. For my chemistry experiment, I decided to find the effect of temperature on the equilibrium constant of the reaction between Fe(NO3)2-and AgNO2- using KSCN to Titrate the equilibrium mixture. My concern is will this method give me sufficient results for the aim of my investigation? Also, I haven't found any applications for this reaction. Please let me know if there are any. thanks
  6. Hi, I started doing my chemistry IA on the effect of temperature on buffering capacity. I added a pH 7 buffer to distilled water and titrated it with NaOH. I then measured the amount of NaOH taken to increase the pH of the water by a unit of 1. I tried this for temperatures between 5 and 80 degrees but there was no significant difference between the data obtained. This there any notable fault in my methodology? I have to finish gathering data for my IA within one week. Since I was going to discuss the effect of temperature on the equilibria of the buffer solution, I am in the process of finding another IA experiment in the same subject area. If you have any suitable ideas or any improvements for my previous method, please let me know. Thank you
  7. Hey everyone, Not sure exactly where this goes, so I'm just posting it here I recently had a situation where the Internal Deadline was reached for my IA, which I only had a draft completed. My teacher, shared on the document, was willing and ready to submit it as my final. In the even of not finishing my work, is my teacher allowed to just send my draft as my final without my consent? Or do they need to ask me first (maybe in the form of some form that I sign "yes, submit this")? Thank you.
  8. I am tasked with writing a math IA for Math Studies, but I have no idea what to write on. Our teacher is heavily leaning on the class to either write about a topic that uses Chi Squared testing or Linear Regression as our higher math process, but I don't know what to choose. I've always been bad with coming up with writing topics, but this one has me totally lost. What are some good topics to write on?
  9. 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
  10. Can someone please grade my IA for me and give feedback. My conclusion is very weak and I feel like my explanations are mediocre. Reply if you are willing to help and I will share a link
  11. So while thinking of an IA topic(TL;DR at the bottom), I ended up going with something related to video games, loot chests to be more precise(In League of Legends). I'll be focusing on the skins that these chests can give to the players and the rerolling system. Basically, if you have three skin shards you can reroll them into a random permanent skins shards. Note that all skin shards have a value attached to them, as well as the final skin itself. You can also disenchant these skin shards to obtain orange essence that is a fixed percentage of the crafting value. I might try to average the amount of RP (paid in-game currency for cosmetics) to equal the orange essence(Can be gained from disenchanting any type of cosmetic item, as well as being bought in bundles with RP) needed to craft these skins to be able to have one unit to measure the value of everything. I wanted to try and calculate the values of everything so that one can determine whether or not rerolling three skin shards would be worth it or not compared to disenchanting the shards and getting the orange essence instead. TL;DR - Loot boxes, comparing the costs of disenchanting 3 skin shards to gain orange essence vs. rerolling the skin shards for a completely random skin. basically seeing at what point is each case more valuable/cost-effective to the player. C&C would be appreciated
  12. Dear friends... Basically it turns out that my original physics ia topic has an immeasurable dependent variable (adding salt to water does not affect its refractive index significantly :'( I tested this out in a preliminary trial), and now I need to quickly find another physics ia topic... I won't explicitly state it because I worry about plagiarism, but basically my Chem EE is about 'x' phenomena, and I can explore this phenomena through a physics aspect by relating it to magnetism and movement. I remember hearing that the IBO does not allow us to "double-dip" EE and IA topics, but I was wondering if it is permitted if the EE and IAs are from different subjects. Thank you.

  14. Hi, I'm taking Latin SL and my we have a new teacher for our class. (he doesn't really know what's going on) I need to know how to format: How do you cite latin translations for the ia when you analyze it? Am I supposed to include the original text along with the translation in my dossier? how do I cite pictures? if you have any links to examples or whatever, that would be greatly appreciated
  15. Basically, I thought I had some really good mathematics in my IA but it turns out that one of my equations was wrong and I can't use that method anymore. However, I still want to show that I have understanding of complex mathematics and I don't want all the work I did to go to waste (I integrated a really gross equation with decimals by partial fractions). Would it be okay for me to present the entire process I did ("I started with x method but I realized it didn't work") so I can still show that work, or would I just seem like an idiot for not realizing the equation was wrong and still putting in so much work to integrate it? Bonus question: Do title page and bibliography count for the 12-page limit? I've heard conflicting answers. Also: My teacher said I have to use the approximate = sign (the squiggly one) for rounded values, but would that apply to a function? It seems wrong to use the approximate equal sign for a function. What if I make it clear that the values are rounded?
  16. Hi everyone, We were asked to think of an IA topic in Computer Science, so I came up with an idea but I'm not sure whether it is acceptable. I thought I could make an application that helps IB students manage their CAS portfolio. So basically, there will be a database storing proposal and reflection forms, and students can fill it up and all this data will be stored in a database. Is this topic acceptable? Thank You.

  18. Do I need to include background information on my IA? My topic is weird, I think it's cool but apparently no one else does since I can't find a single research or even a single web page talking about it. My topic is investigating the relationship between the number of magnets with same pole facing the ferromagnetic sphere in a configuration of a ferromagnetic sphere surrounded by multiple magnets and the magnitude of resultant magnetic field as measured from the ferromagnetic sphere. If you can think of some other research/investigation about this topic please let me know! If not, do I still need a background information section? My entire analysis had some vectors, trig, and some creative thinking trying to create the most reasonable set of independent and dependent variables for graphing. I ended up with the independent variable being the magnitude of the difference of the magnitudes of the combined field strength and the dependent variable being the magnitude of the measured resultant magnetic field strength. Please help!!!! My final draft is due this coming Monday, do I need a background info section or no?
  19. Hello everyone, i am a Math HL student and our teacher is askingus to creat topic proposals for our IAs. Since the level of mathematics used is very important, i want to apply calculus in my ia but i couldnt think of an interesting topic similar to that of modelling rainfall in the sample IAs. So id like to ask for your help and suggest some interesting topics that uses calculus. Thank you!
  20. Hi, I need some help with my IA. I have a database about monthly traffic volume per year. I want to model a function that satisfies with the trend for the last 17 years... I don't know if that is enough for my Math SL course requirements. As well I don't know exactly what to say in the analysis. Thanks. Let me know about any doubts!
  21. Is there anyone here who is good at doing ANOVA? If so please PM me because I really dont know if ive done it right in my biology and chemistry ia's! General feedback on my ia's would also be nice
  22. I am doing Physics SL and thinking about some IA topics. I am interested in drone and would like to investigate on electromagnetic interference on drone/multi-copters. But i don't know what experiment should I conduct and what I am trying to find out. At the moment, I think I can use the Lenz's laws to investigate this topic. Can any physic experts provide some comments/suggestions (experiments, apparatus, formula)? Thank you and much appreciated.
  23. Apparently the page limit is 12 pages including title page, table of contents, and bibliography. I don't have the first two yet, some of my analyses are only in point forms (so might become longer) and already at 13 pages. Can I reduce margins to fit under page limit?
  24. Hello, I found a really good IA topic online for ESS, I wanted to know if it's okay for me to do the same thing? Obviously mine will have different data etc.. but is this allowed?
  25. Hello, If my biology IA data has a linearly decreasing graph but my statistical test shows the data is insignificant, is my IA wasted?
