    Maths IA topic

    Hi, I am trying to come up with a good topic for my maths IA. So far, I have talked to my teacher about doing something with the Newton's law of cooling. I don't want to apply this to tea/water/etc. as I think that would be too simple, because it is what the law is based around. My teacher suggested doing some sort of experiment myself that I can then apply the theory to and come up with my own formula for that specific experiment, but I am having trouble coming up with an idea for the experiment. The only thing I can think of is changing body temperature in a swimming pool, but I am not sure if that will work for an IA. Any feedback or ideas would be very helpful.

    History HI

    I am starting on my HI in history and have decided to focus on the American civil war with the question: How did the fugitive slave act of 1850 aid in causing the American Civil war? Is that a good question? I also am having a hard time finding sources to use for it, so if anyone has any suggestions, that would be very helpful.
  3. thank you both, this was very helpful
  4. hi, So I have my TOK presentation coming up and this is what I have so far. But I am not sure how good it is and wanted someone's opinion. This is my RLS: Dr. Andrew Wakefield falsely found a correlation between MMR vaccines and the causation of autism. This influenced anti-vaxxers, as they began to believe that they were right in their reasoning for not vaccinating their children. As a consequence, from this the measles broke out again in the US. (Claim: MMR vaccines cause autism) His study was based on 12 children – 8 reported to developed autism after receiving the vaccine and that the symptoms began to appear to weeks after then my KQ is: To what extent do personal beliefs require epistemic justification to be valid? In order to analyse this I am looking at reasoning and faith in the natural sciences: claim: reasoning and faith are unreliable ways of knowing in the natural sciences. Then the justification of personal beliefs: claim: it is really important for personal beliefs to be justified, because otherwise they could evoke an ethical dilemma. Then I am looking at if justification of a belief can be achieved. Claim: a belief can be justified. Then my conclusion is that: within the natural sciences, faith and beliefs are not reliable for obtaining valid knowledge. Reasoning is more reliable though, because it can be justified. Ethical dilemmas can arise if people do not justify their beliefs. But they can also emerge if people do. A belief can never truly be objectively justified. It can be subjectively justified through opinions. - within the natural sciences, a belief would require justification to be valid. However; a belief would have to be justified through reason in this case, because a belief is not reliable for obtaining knowledge. It requires scientific justification to be valid. - A belief can be however, be valid to a certain person, because they can subjectively justify their own beliefs. Relation to RLS: an anti-vaxxer does not require justification to be valid in their opinion not to vaccinate their children, because this is subjective and they can justify their own opinion. But within science, a belief would require justification, which there's doesn't, because science has proven that there is no link between vaccinations and autism. Any opinions or corrections would be very helpful.

    EE biology

    I want to write my extended essay in biology but am worried about the originality of my experiment. I want to do something on how antibiotics can change the growth of plants, but I don't know if that is too simple. I have been looking at some experiments, but just cannot figure out how to make it more original. Any help would be very appreciated.
