  1. The information given to me by my teacher is a bit confusing in this regard, so I thought I would ask here: Do we get to choose our own topic (using the core topics) for our written assignment? Keep in mind this is for SL. Any help would be much appreciated
  2. Just to get you interested, for every reply I will send a bad chemsitry pun to that person...and will try to make it original... For my chem IA am going to investigate anti-oxidants in health foods. I thought this was a good idea after hearing about all these "free radicals" in the human body and how they are linked to diseases blah blah blah, but antioxidants can remove them. I want to investigate something in this area whether it be looking at antioxidants in food at different temperatures, or comparing them, but I am unsure which path to go down. If you have any ideas how I can progress this idea further please reply (you will get a good pun) OR if you think this topic is terrible, or think you have a better idea, let me know,
  3. Hi, For my IA I settled on constructing an equation that attempts to model the exponential growth/decay of "something". I would then use line of best fit etc. to make it more accurate. Finally, I would use a 'standard formula' and compare accuracies. Do you have any ideas for things that could be modeled? I figured the population of Egypt but it looks more linear than exponential. I would also like something that has a formula other than the standard exponential formula of P=Ce^t. I should note that I was inspired to do this by a sample IA posted by the IB on the cooling of tea. The three methods as well are taken from the IA. (P.s. Would that be plagiarism? I will make sure no figures/formulas are the same. I would just like to mimic how the student went about answering the problem).
  4. Hi everyone, I have a question regarding the CS IA. For quite some time I could not decide on what I should do, since I'm not a particularly good programmer. I watched some videos on Youtube and saw that some people had made games with an editor known as Fusion 2.5. Inspired by a movie I opted to make a playable version of Peg Solitaire in said editor. I already designed the playing board and both the mouse pointer and the playing marble sprites, as well as got the mouse to fnction. However I doubt that I would be able to finish this project of mine, due to a lack of knowledge with the editor. This is the point at which I should point out the big issue, said being my teacher. He is not a quallfied IB teacher, he isn't very good at English and I doubt that he knows anything about the IB or CS in general. So far he was unable to provide me with any concrete details on the rules of what I need to use to make my product. To this day I do not know whether or not my project is appropriate, and as the deadline aproaches, I have less and less faith in it. This got me thinking as to whther or not I should change my topic, and after some time I remembered how I made game modifications for The Elder Scrolls 3 in it's respective editor. Naturally this mod would include custom coding for a quest that could have value both in terms of entertainment and education, for example: explaining chemisty through interaction with in-game characters. The issue with this is that I would need to use already existing character models and assets for the mod to function. I'm intersted as to whether someone has made something similar in the past as well as whether or not my ideas for the IA (both the marble game and the mod) are a good idea. I'd prefer to make the mod one, since I'm more experienced withe the editor. Thanks in advance guys! Ozren
  5. Hey I am stuggling with my history paper. Can you tell me if question do you: How and to what extend Russian minority enriched and influenced cultural development of city of Lodz during 19th and beginning of 20th century? or To what Russian minority in Lodz contributed to the development of the city in 19th and 20th century? are they good topic for IA because I am not sure,.
  6. Hi everyone! Recently I have had all of my wisdom teeth removed and given to me, and I was wondering if you would have any ideas as to how I could incorporate them in an IA. Could I do something with bacterial growth? Thanks!
  7. Hi I asked my chemistry teacher if I could investigate voltage change of galvanic/voltaic cell by changing the size/surface area of the electrodes and he said yes. So i conducted the experiment and found a bit increase in voltage as the size increased, BUT my problem is that I havent found any source that supports it becasue all the sources state that voltage has nothing to do with size of electrode, but resistance has. According to my teacher, I should stick to the topic because other students have done it before me and gotten a good grade , but I cant find anything that supports my experiment. Does anyone have an idea or have done similar experiment? I am in a desperate need of help so any kind of answer would be so much appreciated thanks,
  8. 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
  9. Hi, For my math IA, I chose to model traffic flow (worst choice of my life .... kinda above my math level). My aim is something along the lines of "how does an influx of vehicles cause traffic congestion." The formulae that I am using are mean, poisson distribution, speed, and density (so far). I have good knowledge of the models too. Tbh I could rant on about traffic flow for 12 pages, but I don't know how to make my IA fluid. Any help would be appreciated! Thanks.
  10. I'm currently a junior in high school, and technically am in honors PreCal, and will take AP Calculus/IB Math SL next year, but we're coming up with topics for our IA already, and I'm lost at where to go. Some topics I have in mind: - Creating equations that model the spread of disease (I want to go into a career biology/medicine related) but I don't know what direction I would take with this kind of assignment... - Sine graphs and modeling pitch/chords - really wanted to do this as I'm a musician as well, but I looked at an online example of this type of topic that did poorly and I am concerned I will not be able to explain and incorporate good deal of math to get a very high score... - Something related to the Monty Hall problem also seems interesting, but it seems very statistics-based and while I am good at basic stat, I haven't covered many higher level stat-content in my classes. Any help/suggestions is greatly appreciated!! While I have managed to maintain high A's this year in math, I have no idea how to expand upon what I what I want to do with my IA. The IB life is just starting to catch up to me.
  11. Hey guys I have the first draft of my Bio IA due sometime in the first week of February. My research topic is: " What is the effect of temperature on the activity rate of amylase". Right now I'm having trouble finding a way to get my materials together. My top priority is enzymes as we can borrow scales, beakers and etc. I've been searching online but with no success. On Amazon they have a good deal, but it won't ship to Canada. I saw this other website but the approximate time it takes to ship from their warehouse in Montana to Calgary takes 2-3 weeks, which is past my deadline. As a last resort if I cannot get enzymes, I'm wondering if I could use saliva as it has amylase to convert starches to sugars or use another enzyme (trypsin, but I think this is harder to find). Where do you guys get your materials for your IA? On a side note, I need a way to regulate high temperatures without the use of the incubators we have at our school because our lab technician says most of them are being used for chemistry IAs. -PW
  12. Hey guys, I was just curious about what you guys think about these assignments above. Which one do you have the most and why?
  13. Hi, I was just wondering if I could get some input (or mere approval from current/former IB students) about my chemistry IA research question. Is this a common lab idea? I haven't really seen it anywhere so I'm not sure but I would like to make mine unique. Is it a realistic experiment to conduct within 10 hours? "How does cooking time affect the vitamin C content in various vegetables?"
  14. For my IA, I am trying to determine the conductance (ion flow) in different drinks such as distilled water, Gatorade, Powerade, coconut water, orange juice, Pedialyte, and a solution containing sodium chloride. I was planning on doing this by using a digital multimeter and measuring the resistance of the substance and then taking the inverse of it to get the conductance. I would determine whichever substance had the highest conductance and by doing so, would be able to find the substance with the most electrolytes. Growing up playing sports, I have always been told the importance of staying hydrated as well as replenishing electrolytes after vigorous exercise, and I was interested to see if sports drinks like Gatorade and Powerade were really the best substances for athletes to drink as these companies have claimed. I am worried that my "experiment" is too simplistic since I don't really have any variables. I was wondering if this was enough to do for the IA or if not, I was wondering if there is a way I could alter the experiment a little bit so that it would be more challenging. One idea I had was to take the ingredients of the different substances and "rebuild" the electrolytes found in them. For example, Gatorade contains 230 mg of sodium in 500 mL and 65 mg of potassium, and I was planning on creating a solution with the same concentration of sodium and another with the same concentration of potassium. Then I would add up the conductance of both substances and compare it to the original Gatorade. I have no idea if this would work or even if it makes sense. Thanks in advance, Jerry
  15. Hello! I am conducting a survey to collect data for my Math SL IA, and I would like it if you took some time to take it! The link is below: https://docs.google.com/forms/d/e/1FAIpQLSddox1gjDoGIE46DPZxVI4tHEf4DXgER2gz66roHHVtW_cDBA/viewform Thank you!
  16. 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?
  17. Hi, I'm in the process of writing my math IA and wanted some feedback on my topic. I want to create exponential functions demonstrating the behavior of the S&P 500 in the past 50 years, as well as the GDP of the US. I then want to try to find some kind of correlation between the two functions. I'm in Standard Level Math and am concerned that the level of math in what I propose above is not at the level I need to receive passing marks on my IA. Can someone tell me how I can improve my plan, or if it simply won't work? Thanks!
  18. I did a practical on radial hydraulic jumps and I need to explain the theory behind it. I know how to calculate the pressure using pressure=phg formula but I don't know how to relate the water pressure and the velocity of water. I searched for some equations but they are way to complicated and I don't understand which one to use since they seem irrelevant to my situation. Could you please tell me an equation that simply relates the water pressure and its velocity? Also mention what each variable in the equation refers to. Thanks
  19. Ok so like if I get a 7 on the SL math exam and i only get a 1 on the exploration/ia, what would my final mark be approximately???
  20. So I have been struggling very much with my Business Internal Assessment, it's been absolute hell. I didn't hand in the first draft so I never got it marked and I've missed the internal deadline for the final and I haven't even completed it. I never thought it would be so hard, after all I also did an extended essay on business too. I've been pulling all nighters for almost a week now and I just can't get it right so I'm thinking of just handing it terrible like that. How much would a bad IA affect my results? I'm a predicted 6 but with how my IA is going... Im afraid I wont be able to get my IB Diploma. If I were to score a 3 on my IA for example and a 7 on the exams, what result would my final be? a rough idea? I am in need of a bit of consolation. This task have given me so much anxiety, I've lost my appetite and the will to do anything.
  21. Hello! I literally just came up with this idea (I've been searching all morning) and I was wondering if this theme for my ESS IA would be approved and if it is, how can I carry it out? You know how we discard all types of products in the sink and all of that goes to our oceans and rivers? Well I wanted to test out how can different products with different ph leves affect the growth of plants. I know the question is still too broad but like I said I just got the idea. Any feedback would be genuinely appreciated!
  22. Do you think this topic will work? This is my History HL IA for the new syllabus. To what extent does the interpretation of Japanese constitution article 9 affected the revision of the US-Japan Security Treaty in 1960? If this doesnt work, do you have any suggested topic in this field?
  23. ---Author's Note--- This is the third draft of a concise guide I'm working on in regards to the new mathematical exploration IA; this started as an HL guide but has now been generalized to include the SL curriculum as well. Please do let me know if there are any improvements you can suggest, or any questions you have after reading through this. I plan to keep this updated and add to it as I work though my own IA. Thanks for taking the time to read through! ------------------------ Table of Contents Preface and Introduction to the Exploration The Process (to be added) Formatting (to be added) Acceptable Topics (SL) Acceptable Topics (HL) Grading and Evaluation​​​​​ Criterion A - Communication (to be added) Criterion B - Mathematical Presentation (to be added) Criterion C - Personal Engagement (to be added) Criterion D - Reflection (to be added) Criterion E - Use of Mathematics (SL Only) (to be added) Criterion E - Use of Mathematics (HL Only) (to be added) Sample Papers Postface and NotesPreface and Introduction to the Exploration The Mathematics SL/HL Exploration internal assesment. It is certainly a difficult assignment - a paper on math isn't the easiest thing to write. I've written this guide up to clarify a few questions and hopefully help out with your work. However, please don't just trust what I say do some of your own research as well because I cant hope to claim everything I say is entirely accurate. I hope this helps! In essence, this is an exploration of a topic in mathematics that has a real-world connection, done in a rigorous manner that connects back to the material we have covered and will cover in class. 6-12 pages in length should be appropriate enough to concisely explore your chosen topic with the depth required and complete the necessary parts of evaluation as shown in the rubric. You want to write at a level and regarding mathematics that is accessible to other students. For HL students, this generally means anything within the HL core curriculum and any option is fair game. Just be certain to provide requisite explanation for any material beyond those two areas and for options not covered in class, to the extent that your classmates can understand the work you've done with some thought. The Process <to be added> Formatting <to be added> Acceptable Topics (SL) <to be added> Acceptable Topics (HL) I've been asked a lot of questions about acceptable topics for the IA's mathematical focus. These acceptable topics are mainly focused towards fulfilling the part of Criterion E that requests "sophisticated mathematics commensurate with the level of the course" - more detail regarding the other aspects of this criterion can be found in the Grading and Evaluation section slightly later on. One guideline I've heard from a few sources is to choose something beyond the SL syllabus: a summary of those topics can be found slightly later in this section. Keep in mind you do not have to restrict yourself to these topics, and anything beyond is fine. Also, that a topic in the SL syllabus can be beneficial if done well - it's rather easy to do comparatively and can still net you a 7 on the IA. See the Florence Nightingale Sample IA. Finally, I'm not certain if all of these topics have sufficient levels of difficulty, or if there are any in the SL syllabus that would be acceptable this is simply based on the SL and HL syllabi. What follows is a list of the topics which are in the HL syllabus, but not the SL, to provide a guideline of all acceptable topics within the syllabus: Topic 1: Algebra 1.4: Proof by induction. 1.5: Complex numbers, the Cartesian form of a complex number. 1.6: Modulus-argument of polar form of an imaginary number and the complex plane. 1.7: Powers of complex numbers, nth roots of complex numbers, and de Moivre's theorem. 1.8: conjugate roots of polynomial equations with real coefficients. 1.9: Solutions of systems of linear equations. Topic 2: Functions and Equations 2.1: ONLY domain restriction for inverse functions as well as self-inverse functions. 2.2: The graphs of y=|f(x)| and y=f(|x|), the graph of y=(1/f(x)) given the graph of y=f(x). 2.5: Polynomial functions and their graphs, the factor and remainder theorems, the fundamental theorem of algebra. 2.6: Viete's theorem, or the sum and product of the roots of algebraic equations. 2.7: Solutions of g(x)>=f(x) by graphical or algebraic methods for polynomials up to degree 3. Topic 3: Circular Functions and Trigonometry 3.2: Definition of the reciprocal trigonometric functions sec(x), csc(x), and cot(x). The tangent-secant and cotangent-cosecant forms of the Pythagorean identity. 3.3: The tangent double angle identities, compound angle identities. 3.5: The inverse functions y=arcsin(x), y=arccos(x), y=arctan(x), and their domains, ranges, and graphs. Topic 4: Vectors 4.2: The properties of the scalar product of vectors. 4.4: Specifically intersecting and skew lines in distinguishing between coincident, parallel, intersecting, and skew lines. 4.5: Definition of the vector product of two vectors, properties of the vector product, and the geometric interpretation of the magnitude of the vector product. 4.6: Vector equation of a plane, use of normal vector to obtain a particular solution form, Cartesian equation of a plane. 4.7: Intersections of: a line with a plane, two planes, three planes. Angle between: a line and a plane, two planes. Topic 5: Statistics and Probability 5.4: Use of Bayes' theorem for a maximum of 3 events. 5.6: Poisson distribution. Topic 6: Calculus 6.2: Related rates of change, implicit differentiation, and the derivatives of the inverse trigonometric functions, the reciprocal trigonometric functions, the exponential function, and the logarithmic function 6.7: Integration by substitution, integration by parts. All material in all option topics. Grading and Evaluation You can find the grading scheme for this IA here: http://bit.ly/1iOdQl7. There are 5 criteriae: communication, mathematical presentation, personal engagement, reflection, and use of mathematics. To clarify a few terms used: Personal engagement refers to the intent of the investigation to develop your interest in the area, and its evaluated based on the visibility of your personal engagement in the area and your own individual expression of those ideas. Precise and correct are differentiated by the need of precise mathematics to include proper notation and completely accurate work whereas correct mathematics can contain some errors as long as these errors don't lead to egregious incorrectness. The criterions themselves are defined here in the markscheme. Criterion A - Communication <to be added> Criterion B - Mathematical Presentation <to be added> Criterion C - Personal Engagement <to be added> Criterion D - Reflection <to be added> Criterion E - Use of Mathematics [sL] <to be added> Criterion E - Use of Mathematics [HL] <to be added> Sample Papers Its difficult to understand and conceptualize what is expected without exploring some examples of strong work. So here are a couple example papers, to show you what other students have done in the past, how theyve been evaluated and annotations, the mark they received and grader comments, as well as a couple small notes of my own. Sectors, Arcs, Descriptive Statistics, and Florence Nightingale (Mark Achieved: 20/20 at SL, 17/20 at HL) Paper: http://bit.ly/18KcK5q Paper with Comments: http://bit.ly/1fFkYe2 Marks: http://bit.ly/1dBrz7z This one is a perfect example of the kind of work you want to be doing in your math IA - however, the level of mathematics isn't at a high enough level given that all mathematics used is within the Math SL curriculum. Differential Equations and Modeling Rain. (Mark Achieved: 16/20 at SL, 15/20 at HL) Paper: http://bit.ly/1c491Oi Paper With Comments: http://bit.ly/19KUPKw Marks: http://bit.ly/1d6PSMD This paper has many errors in notation, it is not concise in form, the reflection is not critical, examples are not quite sufficient, and the mathematics is not precise. However, the mathematics is certainly at the level required. Very strong work in general, just missing that final layer of polish. Postface and Notes I hope I've been able to help out with this guide. Please let me know if you find any issues or inaccuracies or if you still have questions after reading through this. Good luck with your IA! Sourcing Notes: A good deal of these links and some of the information was retrieved from M. Chao's blog, which can be found here: http://bit.ly/K12vhF. It was quite useful to me in doing my own research.The IB Mathematics IA website was very useful to me: it can be found here: http://bit.ly/JbK1e4.The SL and HL Mathematics IB Course Guides were useful to me, especially in the analysis of acceptable topics and criterion E.

  24. 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?
  25. Hi In my voltaic cell experiment, Im looking at if changing surface area of electrode changes the voltage I did the experiment and found out that there was no significant change, meaning almost all electrodes resulted in same voltage Can someone please explain why because I really do not understand? Any type of answer is appreciated thanks,
