  1. Hey guys! I'm currently working on my math IA which is on the Enigma Machine and I'm really stressed out about it and I feel likeI'm going to fail. Do you know what happens if you fail an IA? Do you not get the diploma or does it just lower you grade as it's 20% of your mark?
  2. After finishing my IA I realized that my data points failed me. I was testing to see if ethylene had any effect on seed germination, but I rarely even got more than three germination's in a trial. Can I turn in an IA that doesn't have any calculations done because the data wasn't adequate? Or is that not an Internal Assessment?
  3. Hello! I'm stuck with my business IA, which is essentially should _____ stay in the country that they currently are in? Or should they expand into another country? Does this topic work? Should I basically end up comparing the current country they live in to two other countries? I'm really confused as to what financial data I should even get from them. I have the majority of their data from this current year, but should I attempt to get data from several years prior? I'm planning on conducting a SWOT analysis, a forcefield analysis, and a decision tree, but other than that, I really don't know. Any and all input would be really appreciated, as I don't really know 100% what I'm doing at all here. Thanks a billion, guys!
  4. Hi everyone, I was curious if you guys could give me some advice on how to maximize my points for the IA that I have. It's due in one day and I'm retouching it but I have a few concerns. I have a pretty edgy topic that ended up not going too much in my favor for reasons out of my control (but I didn't want to switch topics because it was too late). It is a database IA, so no procedures or such. It is on the effect of electronegativity gap between atoms in diatomic covalent and ionic compounds on the melting point of those compounds. I talk a lot in my background about intermolecular forces, lattice energy, etc. What I ended up discovering was that there really was no noticeable trend due only to electronegativity gap increases which created stronger dipoles. I read into this and it appears that it had to do with the atomic radius and ultimately the distance between the atoms in the compound itself. Thus, since electronegativity and radius are both fundamental properties of elements, it's sort of impossible to isolate either of the variables due to the fact that they are both present in Coulomb's law. My question is that since my hypothesis was that there would be a trend due to the electronegativity gap, is it ok that I'm wrong if I explore the reason for my error? I decided that I could choose three or so compounds with similar distance between the atoms to keep that more or less constant and then see the effect of electronegativity increase on the melting points. Is that a suitable path? Also, since I am wrong in my hypothesis, what would I put for error since really it's kind of the entire thing? I don't expect to get full marks simply because of the topic's inadequacy, but I'd like to maximize my score and get at least a B (6). Thanks!
  5. URGENT Q: I am currently writing my Math SL IA. My teacher mentioned that the "header" of our paper should contain our IB candidate number, but he did not specify and was not sure. Please explain exactly what the header should contain and where it should be located (on all pages, just title page, etc).

  7. Hey guys. So I've finished my EE, my IAs.. everything except my chemistry IA which is proving to be a real pain. My topic was the percentage by mass of ammonium in different fertilizers, and using back titration, I found the percentage by mass. The experimentation was easy enough, and that is all done, and my readings are more or less what I expected. However, I am having trouble with actually writing my IA. For my results analysis, all I can write is which fertilizer is the best out of the three. Is there anything else I can write in my analysis or any possible graphs I can include? Please help, this is the only thing I have left to finish, and its due in less than 3 days. Thanks in advance, you guys!
  8. The IAs are due soon and Ive been procrastinating on working on my Comp Sci IA. Now that Ive finally decided to work on it Ive been struggling with an idea. I was wondering if for my product I could create a map for a game, and if so what would be the requirements for the map in order to fulfill the requirements for the IA. Thank You!
  9. When I was listing various topics for my IA, I realized some of these topics have very simple procedures. Will my marks reduce, due to a simple procedure?
  10. Hello, I have been thinking recentely about my Internal Assessment topic. For now, I have Sierpinski triangle, but I am not sure about it right now, and I am now thinking about connecting it somehow with music. Do you think it is a good idea or maybe the initial topic was appropriate enough for IA? Any comments or advice will be much appreciated
  11. Hello everyone, I have a fairly simple (and maybe a bit dumb) question: For your Math Studies IA, are you supposed to do all your calculations by hand, or can you use Excel/calculators? My teacher said something about doing everything by hand, but that seems like too much work. I appreciate any help! /PL
  12. A couple of my friends last year had written their Business IA's based on a business venture one of their family members own. Will it be possible for me to do the same on my own business - which is legally registered and is a profitable organization with scope for betterment? Or is that some sort of an IB-evil?
  13. I'm starting my computer science SL dossier soon and not sure what I want to school's computer science quality is super low so all we're taught is some java programming, we don't cover databases etc. I love compsci, and I do a lot of programming outside class. I can make animated games and programs. What should I do for my dossier? Someone give me some fun idea
  14. I've completed an IA in physics that is part simulation and part hands-on exploration. In the simulation part, I establish an exponential relationship using a simulation (that I made) which simulates individual particles and some calculus. I was wondering if this is perhaps too mathematics focused and risks straying outside the bounds of the task. I end up concluding that there is an exponential relationship, which is then confirmed using theory (from Option C), then I fit my experimental data to the model to obtain some parameters.
  15. I will get immediately down to the problem- I'm DP2 student doing chemistry HL, my IA nightmare started. I'm the only one in my class who didn't manage to get through with my lab within the time period given, my research question was about how changing the concentration of different solutions would change the voltage in a Voltaic Cell. Now I'm rooting for a Database to use, but I can't find a research question suitable to nature of chemistry data available online, I tried computational chemistry but it was either far too complicated based on quantum interactions between elementary particles, or too limited based merely on choosing values to plug in an equation e.g. Nernst equation. I narrowed down my areas of research to IR Spectroscopy but neither I nor anyone I could ask seem to find some kind of correlation or trend I can analyze for IA. If anyone who knows about IR could please help me by providing some kind of correlation or proportionality trend between independent and dependent variable concerning IR Spectra e.g. Trend in fingerprint-region for alcohols?!!
  16. Hey, everyone! I'd really appreciate if some of you guys could help fill out this survey form ( for my ESS IA Any help would be appreciated! Also, a sentence-long answer in the paragraph/dialogue/text based answers will suffice. I just need you to fill it out as quickly and efficiently as possible. I'll bake you cookies if you do ;D Thank you!
  17. hello everyone, So just last week we started our Internal Assessments for both Biology and chemistry and i just wanted to run some of my ideas through here if anyone could help me. So for biology i have decided to do chromatography on chlorophyll in plants. I was thinking comparing the chlorophylls in aquatic plants and land plants and then also putting them through a spectrophotometer. Can anyone suggest anything better or is this good enough for the IA. For the chemistry i'm seriously stuck. I need to talk to my teacher but first i thought i would come here to ask if anyone could suggest a topic for me (doesn't have to be specific). Currently i've thought of rates of reaction, specifically the effects of a catalyst or temperature on rate but i don't know any reactions that i can use. Another one was titration of something to calculate the concentration of something, which yet again i'm really not sure of, and finally something to do with tap water and whether it is safe to drink. I would greatly appreciate if someone would suggest a topic because i'm really stuck and these are all due formally in december. BTW, EE is over with but the happiness of finishing that kinda faded with all these IAs to do, including the history IA. Again, any practical advice or help would be extremely appreciated.
  18. I am doing my Biology IA on the effect of using your dominant and non-dominant hand on reaction times as a response to visual stimuli. If any of you has some spare time, could you do a very quick reaction time test, which will take maximum five minutes, to provide me with some more data? All you have to do is visit this website: You do the test twice, once with your dominant hand and once with your non-dominant hand. Every test consists of five reaction times. Once you do it, could you please post them for each hand for me? This will mean 10 times in total, 5 for each hand. There is no need for the averages. Just remember that after you click once, you should note down the time because only the average is shown in the end on the website. In case you do it, thanks, it will be such a huge help in increasing my sample number
  19. So I have been thinking of a math IA. I have seen some poor graded math ia's online such as the one with minesweeper and correlation between poverty and gdp of a country. I really want to get this math ia some direction. Right now, I'm thinking of a way to use algebra to solve minesweeper or build up on the poverty/gdp of a country. These are my only 2 ideas, can you guys help me with some ideas. Also, can you suggest ways for me to show the correlation between poverty and gdp of a country.
  20. What I'm planning to do is test the effect of pH on algae growth, but I'm not sure how I'd manipulate the pH (should I use HCl or something?) or how to make algal media (is it sugar, sea water, and plant fertilizer?). Thanks for all your help!
  21. Hey guys, I am going to be brief. I am a little bit lost with my 2nd commentary. It seems easy as it is a very straight-forward work and doesn't require much research. The thing is I guess I haven't actually grasped the essence of writing an Economic commentary. Is it supposed to just explore and explain the discussion in the article, illustrating it with economic theory and diagrams? Or should I produce a discussion myself, with arguments in favor and against, even if they are not mentioned in the article? For example, I am doing on tariffs on China. And as you know there are several arguments against and in favor as to protectionist policies. One that occurs to me is the fact it gives government revenue. But on the article it does not mention it at all. But lets imagine I am actually fond of this argument and could explain it and analyse it neatly. Could I develop and illustrate it on my commentary? Or should I just stick to what the article says and just assess it eventually on the conclusion? Please, I really needed some advice or some general tips on what really consists an Economics IA. Thanks in advance, you can PM if you want.
  22. Hi guys, could you please help me with my internal assessment? I just finished the final draft and.... there is an excess of 240 words... could someone message me privately so i can send it and they can read it and help me? Thank you
  23. Ok, so I'm doing my chemistry IA and I'm not really sure the level I need? I'm feeling like I have a really generic question at the moment. my question at the moment is 'How does increasing temperature affect the equilibrium constant in an esterification reaction?'. As far as I can tell its been done probably a lot before, but I've already done quite a bit of work on it and would like any suggestions on how to complicate it, or make it more unique? I was basically just hoping to get any advice/feedback. Thanks!
  24. Hey everyone, Our experiments for our IAs are starting soon and I am not sure which statistical analysis to use - here is my experimental method and idea so far (haven't checked it with my teacher yet, any improvements or suggestions are welcome!) To look at how pollution affects plant growth I want to investigate the affects of acid rain on seed germination. I would do this by growing my own cress, but watering the different cress plants (in separate pots) with water of different pH, so to simulate normal rain water I would use water of 5.6 (pH) and to simulate acid rain I would use a pH of 4 or lower. I am not really sure yet how I will split the plants up and how to measure the effects other than observing but once again, if you have any advice, that would help me a lot! Now to my actual question: How do I analyse my results statistically? I was thinking of using the t-test but I am horrible at statistical analysis. Thank you!
