  1. yep my friends used it as creativity: they knitted a final product. OFC to make sure you shld ask ur supervisor
  2. Hi thanks for your response! I was quite silly to not clarify in my post that I'm doing a database 🙄😅 sorry 'bout that!. And the root of my question I guess is in my background information I talk about limiting factors such as temperature and ecological niches; would it be wrong to apply that to a genus rather than a species? Because most research, litreture, on corals is about their genus rather than species. Species ( which is more specific than a genus) was thus hard to find data on. Thank u
  3. Hi guys, This is pertaining to the ecology unit as well: so I'm doing my IA on how an abiotic factor of temperature effects corals. Except I just realized that all my data involved a genus of corals, rather than a species of corals. So I've been investigating the effect of a genus on temperature, but my background pertains to species ( such as ecological niches and species, abiotic factors being limiting factors, natural selection for species). What should I do? Should I apply all this background to investigate a genus and list off the fact that I could not get data on a single species and therefore it is a limitation in the end?? I really hope I haven't messed up my bio IA. help, please!!
  4. So I'm doing a rate of reaction IA with different catalysts. I've calculated the standard deviation and shown them as error bars on my graphs. Now, do I need to calculate absolute uncertainty and if so, what do I do with the calculated values?? Help would be awesome.
  5. 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?
  6. You absolutely can improve. Grade 11, first IB year was so bad for me I was getting like 70s in math and not my best in other subjects either. So in the summer, I studied, and in the second year I broke most 🙈 of my bad habits, and yeah I feel more confident. You have loads of time to improve but start now. Work on your weaknesses, try to study ahead in the summer cuz grade 12 becomes a little bit easier and dont allow yourself to procrastinate. Delete all your social media or whatever hobbies distract you. You can do it!
  7. Hey guys, working on my works in translation ( for final hand in to IB). In class, we talked about psychological setting briefly when discussing short stories. It was basically tone, mood and atmosphere. But im unsure because we only touched upon it. However, in my essay, I want to use it. I searched it up to clarify the meaning of this type of setting but can't find anything. Do you guys know what psychological setting is in literature? I want to know for sure. Thanks!
  8. Hey, In terms of memorizing studies ( ugh torture) it was basically me remembering each study in terms of Aim, participants, procedure and Results, And then I'd have a few key points for discussion such as limitations. I did this because examiners look for these points right away when talking about studies I'd write them down on cue cards, constantly review them. I'd write them in places I could see them so that I could glance at one or two on the train. That's why it's important to start reviewing in advance so you can just review. Although if u are short of time u can still manage because I still did end up cramming allot of studies the few weeks before the exam. Other than cue cards, I also repeated them out to myself, I tried searching up the main studies on youtube cuz watching a visual of the study helps. For example, the crash course helped me remember that Bandura study...I'm surprised that I still remember some of these studies 😮 I also typed up my studies onto an online reader so I could hear someone repeatedly read out the study to me. Different ways of memorizing it helps. Also, a good idea overall is to have some main studies you know super well and try to reuse them as much as you can. Like H.M for localization can be analyzed from a cognitive and biological perspective. Good luck!
  9. Hey guys, so my EEs is on risk perception of GMOs, and how this influences implementations in countries. So I have psych as part of my interdisciplinary and bio. So do I do APA citations or MLA citations??? I'm so confused and this is due tomorrow and i just realized this. Welp
  10. hey guys, I am planning on doing my chem IA on different catalysts impact on the rate of reaction of decomposition of hydrogen peroxide. I was planning on measuring this rate of reaction with gas pressure ( with gas pressure sensors). My different catalysts are manganese dioxide, Potassium iodide, catalase, iron dioxide and lead oxide. So 3 transitional metal catalysts, one ionic compound and one organic compound as my catalyst. But now I am beginning to have second thoughts on this topic because ultimately I am not using a quantitative value as my IV. I've just chosen 5 different catalysts. But I'm not sure how I would hypothesize which catalyst is better than the other, and when I get my results how I would justify. Is me having these types of catalysts as my IV rather than some quantitative value a potentially bad thing or more likely to have a bad impact? Because I dont know how to form my hypothesis and I could not find much research online (quite frankly I dont even know what to look for). So some guidance here would be awesome. : ) so should I try simplifying my topic into perhaps ": varying the concentration of one catalyst and its impact on the rate of reaction of hydrogen peroxide? is that too simple? is my previous topic fine? I feel like I am going in circles.
  11. This question is definitely a great starting point, however, if you want a good and detailed argument (claims and counters) you need to be even more specific. For example in your question, consider: what sort of knowledge? Contextual knowledge? Emotional based knowledge? Is this knowledge the truth? Clarify this. And for the second part of your question consider what types of behaviour? Emotional responses to the historical event? Biases towards different sides? Because really anything can be behaviour. I feel this part of the question could focus on emotion so that your overall question basically ask how does a specific type of knowledge of a historical event impact some sort of behaviour (which is influenced by emotion.) It's up to you what sort of behaviour you want to study. Just some outside perspective and suggestions. Overall, your question is really interesting, just have to narrow down a bit more. Good luck!
  12. hey, well here is a list of ways my teacher suggested in class -measuring the diameter of the stem: how wide it is. You can use measuring tape or string -measure the height of the stem in cm -leaf size can be measured without taking them off, just measure across or from the bud to the end with a measuring tape/ or string. Although I do admit this may be more tedious -you can even try measuring the heaviness of the plant. That would entail measuring the pot with soil at first before the experiment. And then every time you measure your plant in the pot, you subtract the pot and soil weight. Good luck!
