  1. For my IA this year, I was given the topic of exploring surface area and drag. The assessment requires me to produce a graph with a meaningful gradient. I am using the drag equation to formulate my graph (where Fd = 1/2 p u^2 Cd A) and when I plot drag force against area I get the gradient as (2 Cd/ pu^2). My question is if this gradient is useful? Surely the graph implies the the drag coefficient is a constant, but surface area is changing. Any improvements and/or changes to my possible graph would be much appreciated.
  2. I have just finished my product for my ITGS IA. I am doing a DTP software using photoshop. However, my client gave me pictures that can be found in the internet. I absolutely have no idea about this. What should I do? Please help!
  3. hey, i have to submit my ee topic soon and i was just wondering other than length of the writing and marking scheme, what's the difference between a topic chosen for ee and topic for ia? I'm asking this since i fear that i may choose something for my ee but wish to write something like that for the ia (which isnt allowed) If someone can answer my question that will be very appreciated, thanks for the help!!
  4. I am calculating for the vitamin C concentration of different fruits and using the formula = Molar mass of vitamin c x concentration of DCPIP x volume of DCPIP used. I am confused on how to search for the uncertainty value. Can someone please help me???? Thank you very much!
  5. 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!
  6. 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!
  7. 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.
  8. 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. 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
  11. 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?

  13. 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:) https://goo.gl/forms/D5HvaJpxtSFxZdgt1
  14. 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
  15. 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
  16. 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.
  17. 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
  18. 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
  19. 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
  20. 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?
  21. 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?
  22. 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
  23. 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
  24. 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 (?)
  25. 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?
