    Chemistry IA - 13 Pages

    Hello guys, Simple question, but maybe not as simple answer - Can my Chemistry IA be 13 pages long of the 13th page includes only the citations? I understand that the maximum page number is 12, and I tried to reduce the IA as much as I could, but I am stuck at 13. Thanks a lot 🙂
  2. a) Using diagrams, explain how a change in one of the determinants of demand might increase the price of rice and how a change in one of the determinants of supply might decrease the price of rice. This is the part a) question my tutor gave me and I don't get it. Please help xx.
  3. As you know, for the criterion E of ITGS IA, it says I must use at least three advanced techniques from the list. I am making a website, so I think I must focus on the "multimedia" section. The website was created using WIX. I first wrote about html coding, where I created tables to introduce the products. HTML was also used for paragraphs and introducing the company as well. Secondly, I wrote about Integration of components using advanced features from other applications, that is embedding google maps using html. Lastly, I indicated the Proficient integration of the different elements of multimedia. Here, I talked about creating slideshows and adding various effects using WIX features on the background images. However, I feel these three explanations are too simple. Do I have to add more techniques so that I can show that the techniques are advanced?
  4. Hey, My topic for my Chemistry SL IA is the quantitative analysis of vitamin c in raw tomatoes compared to cooked tomatoes. I thought about making 5 repetitions because of the certainty. I will get 5 results overall. Is that enough? Or do I need more repetitions? Is this topic even useful? If not, what do you request? I'm open for ideas! PS: I have no time left, deadline by tomorrow. Thank you
  5. Hi so I'm thinking of doing my IA on the Racial Equality proposal and am tossed up between these questions: To what extent did Australian opposition of the Racial Equality Proposal during the 1919 Paris Peace Conference impact its failure? What were the reasons for the failure of the Racial Equality Proposal during the 1919 Paris Peace Conference? What were the reasons for Woodrow Wilson's rejection of the Racial Equality Proposal during the 1919 Paris Peace Conference? To what extent was Billy Hughes opposition to the Racial Equality Proposal justified? To what extent were the goals of the Racial Equality Proposal achieved by the United Nations Charter of 1945.

    Math IA Projectile Motion Help

    Hello everyone, currently I am writing a new math IA and i decided to write it under the topic of Projectile Motion. What what I want to do is take a video of a setter (in volleyball) and him setting the ball up. I'll take that video and create a graph and will derive that function. The thing is, I think that this is a little to vague, and I really don't have a clue on what to really explore within my topic. For the volleyball idea, I wanted to originally see what's the best place to put the ball in the air to get a good hit in for the spiker. If you have any further suggestions on what else I should do with this topic, I am open to any suggestions. Thank you!
  7. Hello! I am a grade 11 HL History student, and have the task of choosing a topic for both my IA and EE. I am very interested in ancient history, e.g. the Roman Empire, Alexander the Great or the Greek city states - I told my teacher that I would like to write either the HI or EE on one of these (most likely Rome), and she said that the one glaring problem with such topics is the lack of sources and the need to rely on secondary sources, since these events took place thousands of years ago. For those of you who have written either the Historical Investigation or Extended Essay on ancient history, what do you think of this? Is it any more difficult to find good sources than for an event that happened 70 years ago? Did you have enough sources? Thank you!

    (ASAP) pH 10 buffer solution recipe

    Does anyone know a pH 10 buffer recipe? I showed my teacher one but we didn’t have10M ammonia so it didn’t work out. This is for an EDTA titration and I’m not sure if ammonia buffer is the only one I can use but I’m desperate for any recipes bc i’m conducting tomorrow!!
  9. Hi, I need help with my Physics IA topic. I was deciding on conducting my investigation on Hooke's law and springs. I was thinking of investigating the effect of the length of the spring on the spring constant. Another idea I had was investigating that if a spring with a spring constant of k was cut into four equal springs, would the spring constant of each spring be 4k. I was told by my Physics teacher that this would make a good IA if I was able to explain it correctly, however, I am still unsure. Would this be a good physics IA topic, is there anyway I could expand on the experiment, or should I look for a better investigation? Anything would help Thank You in Advance!!!
  10. HI! So, I'm trying to modify my bio IA rn, but I'm running into some problems. Initially, I was wanting to use Mimosa pudica plants to test the effect of salt concentration on turgor pressure, but apparently my plants may not grow out in time. Does anyone have any ideas about how I can do this experiment with something else? Thaaanks!
  11. I didn't do in-text citation for my math, biology and geography IA. Am I gonna fail IB?

    IB Math SL IA help needed!!

    Hi, so for my IA topic I chose to explore if there's a correlation between race/country and adoption. I've run into a problem though because I'm focusing on 5 different countries and then the number of adoptions from each of those countries over 19 years so I have 5 seperate scatter plots. If I try to find the correlation based off each scatter plot, it would be between the number of adoptions and years for just that one country, instead of all the countries and adoption rate as a whole. How can I fix that? Do I look at it a different way or am I just focusing on it the wrong way? Please help!!

    Math IA - Correlation

    I really need some help rn. I'm thinking of doing a math exploration in the topic of Correlation between GDP Per Capita and Gini Coefficient in Countries. Basically, Gini coefficient is a measure of income equality in a country. The higher the coefficient is, the higher the income inequality. However, the mathematics skills & analyses I will use & do will probably only be from the topics of descriptive statistics and linear modelling. And so far, the IA samples I've seen with similar topics in correlation are only from math studies, so I'm getting concerned. is this topic too simple?

    Summer between DP1 and DP2

    Hi! This forum is to talk about the summer between DP1 and DP2! For example what to do/study, first drafts on IAs, CAS and EE talk! Tips and tricks and reassuring comments are very welcome!
  16. I need help in finding a good microeconomics article to analyse for my Eco IA ! It should be latest, maximum Aug 18
  17. I submitted my Bio IA in the first week of December and accidentally reopened it today, only to realize that I'd typed my name in it. I know that IAs aren't supposed to have names on them... what do I do?? Will I be penalized??

    Maths SL IA Matrix Algebra

    Hi, I came up with a topic “What type of function will produce the most accurate model of population growth in country X?” I made scatter plot using data about country’s population in given year. Now I want to use quadratic function to see how would it fit as a model and I’m wondering whether there is other way to find (a, b, c, and d for the equation y = ax3 + bx2 + cx + d) than applying matrix algebra (X = A-1 B) since matrix algebra is not a part of SL curriculum and I’m worried that using it may lower my mark.
  19. Can i do a history IA on art history? It feels like everyone is doing history from the pov of wars and international relations and politics, but i'm really interested in art history (not propaganda, just art). Can I do it? What could i focus on for example?
  20. Hello! I've decided to concentrate on the antimafia movement's history in Italy for my history HL IA, especially on the grassroots levels and general population's opinion, and how they influenced larger movements on a national level such as Libera. I really don't know how to turn this into a question for an analytical study. Can you help me? Also, do you think the topic is too broad? Thank you

    chem IA research question

    Hey guys, I'm having second thoughts about my research question for my chem IA. I'm doing different catalysts (5) for decomposition of hydrogen peroxide. Does the underlined, red text sound too lengthy and awkward? I was wondering if I should group this into a range like " classes of compounds" but I'm not sure and just confused what to classify these names into. Oh, and for reference, my compounds are maganese oxide, iron oxide, lead oxide, potassium iodide and catalase. Any suggestions to help would be appreciated. Any constructive criticism would be awesome RQ: How does the presence of a transition metal, post-transitional-metal, alkali or organic compound as a heterogeneous catalyst, affect the rate of reaction of hydrogen peroxide decomposition, as measured in pressure (Kpa) of oxygen gas, released over time in seconds?
  22. Hello everyone, Right now I'm really starting to seek out topics for my IA. However the ones that I have found interesting so far ended up being beyond my knowledge to accomplish. For example my first idea was : - To establish at which points and in which environment graphene paints would absorb more CO2 then released while they cured and my other topic was : - To investigate pH trends of heavy metal bioleaching with different concentrations of sulphur Could someone give me a push into the right direction in how I could procure the necessary data or what type of procedure I should use? Thank you in advance!

    Design Technology IA Prototype

    For my IA I am building an automatic pet food dispenser. However, the problem is that the materials are unattainable for be because they're so expensive (Im talking almost $1,000, which I don't have). The prototype is a mandatory aspect of the IA. So, can I make my prototype out of different materials than I listed the actual product would be made out of? I planned for the product to be a combination of plastic and stainless steele, but for the prototype I wanted to make it out of wood. Is there a problem with that because from my understanding prototypes are functioning models, but they don't have to be made of the actual material, unless I'm wrong. Please help!
  24. Hey! I have just finished my draft of the Mathematics SL Exploration. I showed it to my teacher and he said that I have to put double space and separate my calculations from the text. I told that if I do that I will exceed 12 pages. Though, he contends that it is okay. Is it really so? In Maths guide there is nothing on double space and all that stuff that we have in EE. Plus it is explicitly written that exploration must fit into the range of 6-12 pages. So I am confused whether I have to do what the guide is saying or what my teacher claims to be true. Help, please!
