  1. How would you recommend rewriting the newer RQ
  2. How would you answer this question: What role do sense perception and reason play in decision making and judgment calls? What claims could you think of? (going with the same RLS) I said that the humans always feel that they are employing their 5 senses to the best of their ability, however this is limited by their subconscious state of mind. We might be sleep deprived, getting over a tough emotional setback, or being selective in our attention ( I also said however that the level of trust one may place on their senses can be higher or lower depending from person to person. A seasoned veteran pilot, would be able to get over the hurdles of sleep deprivation much better than an inexperienced one.
  3. I want to write a TOK presentation question about Human Error. I had something along the lines of: To what extent can human errors negate the theoretical backing of the natural sciences. My RLS was the Jeju-Daegu air korea plane crash - where the crew were negligent and forgot to read all 12 steps of the safety procedure plan - resulting in a crew miscommunication leading to the crash. What are some other questions related to human error? Is the scope of my TOK presentation a realistic one?
  4. I'm in the middle of planning for my TOK presentation How is this as a potential Question: To what extent is knowledge gained through the natural sciences infallible The real life situation from which this was derived is the series of Korean air crashes in the late 90's specifically the crash in Guam. I was thinking that because of factors such as a lack of sleep in the pilots, the fact that the copilot and pilot were new to working with each other, and that autopilot had been switched off (all considered human errors, relating to the human sciences), it didn't matter how solid the theory behind flying planes is (natural science and knowledge gained through it), the fact that there were human errors made the crashes happen. I'm wondering whether a) this is a good question and b) if an onlooker can understand the question without knowing my background research, and c) what assumptions would I make while making the presentation. Thanks!
  5. Thanks! I was thinking of looking at a) history of the criminalisation of art, alongside graffiti, and b) different schools of ethics thoughts
  6. Here is a revised answer: “It may be ethical and even necessary to criminalise art under certain circumstances, e.g., when civilian safety come under threat; however, on the whole, it should be deemed unethical" For the question, I wrote: "What does art as an area of knowledge tell us about the ethics of criminalising expression of creativity? And so, for the answer, is it necessary to remain unbiased, because it would be odd to write an essay/make a presentation only to end it with, "I'm still on the fence"
  7. How is this as a TOK knowledge question: "Is it ethical to criminalise expression of creativity?", to which my answer is: “Although it may be ethical and even necessary to criminalise art under certain circumstances, on the whole, it should be deemed unethical". I was wondering if it is necessary to reference the AOKs or WOKs in the question itself, or if I need to change the phrasing of my question. Other than that, I do think I have a very "TOKesque" question
  8. I do have access to materials. My one concern is that the change in the mass of the nail will be too small to measure. You mentioned uncertainties; could you be more specific?
  9. I've done some research and have revised my topic: I'm planning on comparing the amount of iron absorbed in absolute terms (Fe only) by measuring the change in mass of the iron nail before and after cooking. Then, I would react the iron in the water to create Ferrous Sulfate, and measure its concentration. (This is because Fe II is the best absorbed form of iron). I would then compare the two.
  10. Hi! I’m currently doing my IB Chemistry EE with the topic of Anaemia I’m investigating the effects of putting iron objects in food while cooking to see if that raises its iron content. I got the idea from a project started a couple of years ago to treat anaemia in Cambodia. I’m having trouble with a research question for this, as I don’t quite know what to focus in on. I thought I’d try to replicate the experiment with just a piece of iron; placing iron nails in a pot of water to see if the iron content would go up, and do my EE as an evaluation and comparison of both the Lucky Iron Fish and ordinary pieces of iron But the one dead end I had was that I didn’t have a way to measure the iron concentration of the water. I thought what I would do is pump the water with air to make Ferrous (II) oxide, as Fe II is the best absorbed form of iron. Then I would use colorimetry to measure the concentration but I need at least one sample of FeO with a known concentration so that I can perform the calculations. What are your thoughts on this, and are there any other ways to find the concentration of Iron?
