  1. 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. https://docs.google.com/forms/d/1kb-aDTj8yZnMb875jNNjXextlC4wBqCOjA7Jz_btDLs/edit
  2. 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
  3. 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?
  4. 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?
  5. 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
  6. 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
  7. 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 (?)
  8. 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?
  9. This guide comes from the website excellentassessment.com 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
  10. 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
  11. 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
  12. physics

    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: https://physics.guzled.com/updated-16-ideas-for-ib-physics-ia-investigations/
  13. I have 2 different ideas for my Chemistry IA experiment and am not sure which one is better. Both of them are on ocean acidification of coral reefs. As coral reefs are 95% calcium carbonate and so are seashells, I'm using seashells in my experiment. 1) My first experiment is on investigating effects of varying levels of concentration of carbon dioxide in water on seashells So I will be investigating different levels of carbon dioxide in the water (varying concentrations of carbonic acid) on seashells in distilled water so I'll be carrying out titration to find the neutralising point and apply that to ocean acidification. 2) My second experiment is investigating different methods of alkaline of reducing ocean acidification in a lab setting So I was thinking of using an antacid tablet and a sodium bicarbonate solution to test on the seashell and measure the mass. The seashell with the larger mass difference is the method with the more ineffective method for ocean acidification reduction. I hope this makes sense! Please feel free to ask any questions. Really appreciate the help.
  14. Hello, my teacher gave me a score on my IA with some feedback, but Im confused as to the whole grading scale. I got a 13/24 but is that a bad score? Also, If it is converted to 40% of my grade and worth 60 points did I do bad? Thank you, any help is appreciated
  15. This is a question I always wonder about. Does IB care about IAs being unique and do IAs score less if they have already been done before? Also, is this 'rule' specific to any subject? I'm taking Bio, Chem and Physics. Do I need to think of unique IAs for all of them?
  16. Hi all, I know that journals are the best sources for information in terms of psychology ia's, but would it be bad if i cite sources such as: a slideshare that has concise information about the topic simplypsychology.org psychyogi.org A citation/reference used in a wikipedia article? I am having trouble finding free (clear and concise) sources for the studies I will be talking about in my IA (Pickel 1998, loftus 1987, Yuille & Cutshall 1986)
  17. Hi pips!! I just wanna make sure... So, I have researched about Written Task 2 and according to my research, WT2 ONLY has to have the following: 1. Outline : includes the question, the section of the course, the text (e.g. novel, play) and the aim. 2. The essay However, my teacher told me that I should add an abstract of 200 words. Can someone please tell me if there is a need for an abstract?? Your answers will be greatly appreciated.
  18. Hi guys, Please help me, I need help with my history IA topic: I cannot decide which question to do. However, I am leaning towards the origin topic question, but it is not "IB worded," and I cannot think of a way to make it IB. I think these questions are sufficient, but I really do not know. Any feedback at all would be awesome...I am panicking because section one of my paper is due next week and I do not know what I am writing about yet! Thank you very much!!!!! To what extent did the Spanish Flu impact Spain’s population and religion? How did the Spanish Flu travel from its origin point to Spain? Where did it come from?
  19. Dear all, At our school we have been panicking about the supposed page limit for the internal assessments. It's a new requirement apparently, but tables and graphs take up way too much space don't you agree? Please let us know if this has been the case for you as well! Pretty much all the IB students at my school are panicking! Thanks!
  20. Hey guys so long story short I decided to hold off my IA until the final week, and I need to complete my experiment basically in the next 3 days or so. My teacher gave me a pH metre, so I'm thinking about doing experiments that involve measuring the pH. My initial idea was testing how the temperature of a solution affected its pH, but my teacher said it was too simple as temperature simply changed the kA. Basically what I'm asking is does anyone have any easy topics for a chem sl IA that involve a pH metre, as well as simple household chemicals(not sulfuric acid or anything lol) Thanks so much
  21. 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?
  22. 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?
  23. 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!
  24. 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!
  25. 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).
