IB TOK: Where can I find a real life situation for a TOK presentation?

For a TOK presentation you need to generate your own knowledge question from a real life example. Your presentation offers a critical analysis of the knowledge question.

Real life example 13 May 2014 is BBC’s Day of the Body Clock




General questions

  • What is an optimum amount of sleep to have each night?
  • What can scientific investigation tell us about our ‘body clock’?
  • Does it make sense to talk about a ‘body clock’?
  • What damage does it cause us to ignore our body clock?
  • How far are our lifestyle choices about sleep and food rational?
  • How has the amount of sleep we have varied throughout history and across      different cultures?

Knowledge questions

If you are giving a TOK presentation, generate your own knowledge question. Here are some examples of knowledge questions that arise from the real life example.

  • To what extent is our knowledge in science the product of nature or culture and how would we know the difference?
  • In natural science and one other area of knowledge, what makes a knowledge claim justified?
  • In order to claim that we know something in natural science, what factors should we take into account and why?

In your analysis you could evaluate the counter argument and look critically at the evidence from science and history here which suggests that an 8-hour period of sleep is a product of culture: http://www.bbc.co.uk/news/magazine-16964783
