    My Maths IA needs more maths!

    Hi, So I was thinking of doing my Math SL IA on the use of the Fibonacci sequence (basic, I know) when composing visuals for film and television. I am thinking of taking stills from famous movie scenes and seeing how the Fibonacci sequence is applied and why. I am just afraid that this will turn into a visual analysis instead of a mathematical exploration and was wondering how I can apply more maths into this. thanks!

    Need help focusing RQ

    Hi, so I'm starting my History IA this year and I am having trouble focusing my RQ. I know I am interested in doing something with women's rights. I dont know if I want an RQ focused on how a war, for example ww2, affected womens rights, or how a women, for exampe coco chanel advanced womens rights. If anyone could provide me with advice or anything to help me, I would really appreciate it thank you.

    How do I write a history EE?

    I am halfway through my summer holiday and I have not started writing my EE because 1. I'm very confused as to how to write it in the first place 2. I don't know where to start. My supervisor left my current school and did not really give me useful advice or insight while he was there, he did not even read the semi-draft that I gave him so I still don't know if what I've done is on track or not! I've read a lot of tips on how to write history EEs but most of them contradict each other so now I'm so confused as to how I should structure or approach my question. Any advice or guide will help
  4. Hi, so I'm just getting acquainted to the BIO IA, I thought about investigating How does a change in oxygen concentration affect the fermentation rate in yeast. The thing is, there are most likely experiments done on that topic before. Am I allowed to redo experiments in that case?
  5. My chemistry IA investigates the different activation energy of the decomposition of H202 with Lead oxide and manganese oxide. My teacher told me to plot 1/Temp against Ln x 1/ Average Time taken but not how to actually calculate Ea. How do I get the activation energy if I have the time it takes for the percentage of oxygen to rise by 15% at 5 different temperatures and have it plotted 1/Temp against Ln x 1/ Average Time taken using the Arrhenius equation.

    Physics IA Uncertainties Average

    Hi~ I am writing my physics IA, and have come across a problem: I have data for six trials, and when I am calculating the uncertainty of its average values, which of the two methods should I use?: 1. (max-min)/2 method 2. standard deviation Should I use the first method or the second method for my average uncertainty for six trials? Which one is the method that is generally approved by IB and is capable of getting a level 7 in the internal assessment? Thank you!!

    Biology IA Qualitative Data

    Dear IB Survival community, I am almost done writing the first draft of my Biology IA. I have investigated the effect of different temperatures on the glucose content in Bananas. I have collected pictures of how the Bananas have ripened and included them under the qualitative data section in my report. Now I´m wondering where do I comment on this qualitative data? Do I talk about this in my conclusion even though it is not part of my research question or hypothesis? Thanks for your help guys :))

    History IA Topic

    I have been trying to come up with a really good question for my history IA, my topic is the Hitler Youth. I have thought about doing, how they were important to the third riech, How did Hitler influence the youth,how they influenced the nazification of Germany. I feel as though it isnt in depth enough and i was wondering if anyone had any ideas or suggestions for me
  12. my HOTA IA is due next Thursday and. I'm. Struggling. I wanted to do something in regards to the cherokee nation because my great grandmother was a cherokee indian. I came up with the question: "To what extent did the trail of tears affect the women of the cherokee indians" but my teacher told me it was too broad and to focus in on one of the tribes instead. so I came up with the question: "To what extent did the Trail of Tears affect the passing down of traditions in the wolf clan of the cherokee indians?" She said it was alright, but I'm struggling to find information on it and I really don't know what to do. Does anyone have any recommendations or advice that they could give me? It would be greatly appreciated.

    Help needed for Business HL IA Topic

    Hello there. I have my research proposal deadline coming up and i was wondering if i could get some help on the Research question. Since I'm taking Business HL, it's recommended to conduct primary research onto a local business. The business owner happens to own two separate businesses that operate in the same field- Electronics and Accessories. So i was wondering if it would be allowed to include both business names in the title... or does it have to be focused on one business only? I'd really appreciate any kind of help :) Thanks!
  14. Hello, has anyone there done an IA in chemistry about activation energy and could share some tips or their marks with me? I have a topic of What is the activation energy of the decomposition of hydrogen peroxide (H2O2) in presence of catalase, by measuring the time taken for 10cm3 of oxygen gas to be evolved at different temperatures? Either at different temp or also without catalase and with MnO2? My justification, in brief, is that H2O2 is present in cells and catalase is needed to break it down so that it isn't harmful and therefore low activation point is important (and I want to see a) what it is b) alternatively how does it compare to reaction without catalase). My teacher says that it's not really a good topic because there's no reason for this experiment and perhaps I should at least compare it with catalysts that include elements that are in human body, but there aren't really such as for example we're better off without Pb in our body. What do you think?

    Math IA

    I really really hate math. I am terrible at it, but I just had to take math at school. Therefore, I have to do IA. What is the easy topic for IA in math? I want a good grade in it. The full score is 20, right? Please help. Any ideas?
  16. Hello fellow IB students, I am currently writing my Biology Internal Assessment Lab-design and I am struggling to determine the controlled variables in my experiment. I am writing about the effect of different temperatures on the ripening process of Bananas. (the ripening process in Bananas is controlled by different enzymes). Now my question is what would be the controlled variables in this experiment? Thank you for your help!
  17. Hi guys, I just wanted to ask if you think these topics are suitable for my Chem HL IA: -Either the pH change of water over a period of time and how it is affected by the temperature -The rate of reaction of glowsticks at different temperatures(Using a light sensor). I would be open to suggestions on titration reactions that I could do. Thanks in advance
  18. I need to start getting solid with my IA topic but right now I am just brainstorming ideas and wanting to hear some ideas from peers. So far I only have around three ideas but are fairly common and perhaps not HL worthy: 1) Calcium content in different types of milk ( not sure how to do this one but interested, wondering if I should use the milk of different animals or different processes and procedures) 2) Enzyme and substrate relationship on how changing the amount of substrate would affect the enzyme activity and perhaps the pH as well? ( Biological catalyst, a bit worried that this is too biology, thinking about using catalase and hydrogen peroxide but afraid that it is too common and also would like to explore different enzymes as well) 3) Best material for cooling pack (quite random really...) I don't really have a lot of confidence in myself and due to previous issues, I have stuff in my chemistry academics to catch up on and find it different to concentrate and understand but I'm willing to learn and work hard. Please do suggest different Chem IA topics as well! I would love to hear them and perhaps find one that I really like.

    biology IA idea help

    Hi, i'm struggling with my idea for my biology IA so guidance would be much appreciated.:) i was thinking of investigating the effects of salinity on the rate of photosynthesis in elodea, but is this too basic and easily answered? Or could i compare the effect of salinity on photosynthesis in an elodea, a pond plant, and compare it to a coastal plant?
  20. Hey, so it's that time of the year where IB Year 1's are getting ready to do their Group 4 projects as well as preparing their IAs. I'm totally stumped on what I want to do, but I do know what topic (Ecology) I really like working with animals but due to ethical reasons, I'm limited to what I can do with them so the teacher suggested to mainly work with plants. I would like to do something interesting with them but I need some help generating a solid idea. Help would be much appreciated, so if you do have just an idea or specific topic let me know

    Plagiarism or not?

    So i sent off my directors notebook officially and i only just noticed that i didn't in text cite the lines from the play text that i used. I put all the quotes together and divided aganist my total word count and it makes 3 percent of the overall word count. I did however put the play text in my bibliography, will I be okay or should i be really scared?
  22. How many marks are uncertainties worth in the chemistry ia? If I were to not include them at all how many marks would I lose? If I did them incorrectly how many marks would I lose?

    Is this IA idea good enough?

    Hello! I wanted to compare natural pH indicators (ex, red cabbage and beets) with the standard ones. I was thinking of just doing pH titrations to compare the results of the natural vs standard. Along with that, I was going to produce the pH curves and calculate the pKa value as well as the equivalence points. Is this good enough for an IA? Should I add anything?

    Chemistry IA Help

    Does the IA topic "To study the changes in the iodine value of edible oils such as olive oil, flax seed oil, coconut oil, canola oil and rice bran oil on subjecting the il to heating and reheating at various temperatures." make good sense. I'm trying to link iodine value to nutritional value. Would appreciate any help in putting this together. I'm confused because they now say saturated fat such as coconut oil is better for health and it has a low iodine value. They say higher the iodine value, higher the unsaturation and better for health...so a little direction would help in streamlining the experiment. Thanks

    URGENT HELP WITH ART SL

    Hey everyone. I've justed started my first year in IB and I switched from chemistry to art sl. I only have a teacher for half of my lessons everyweek, and since i've just started I'm very confused. I have no idea where to start or what I should be doing. I'm also seriously confused about what I put in my process portfolio, like do I just explore random topics, or do i start a project and explore within that project. I'm already 5 weekds behind, so I need help pretty badly hahaha Thank youuu
