Biology is ripe for TOK discussion and links, and it seems that every month there are curriculum and TOK-related knowledge issues in the news. This section provides some respources to stimulate discussion and give ideas for your TOK Essay.

Biology and TOK

  • Biology is one of the natural sciences, an area of knowledge.
    • The natural sciences can sometimes be placed in false conflict with the arts or religious and indigenous knowledge systems. These conflicts are rarely helpful to the knower.
  • The natural sciences tend to rely on the ways of knowing of sense perception, reason, language, memory.
    • There are many examples of discoveries made or inspired by imagination, intuition and emotion – however these are then rigorously tested and explained using the scientific method (falsification).

There are many good resources on the natural sciences as an area of knowledge on Mr Hoye’s TOK website. This includes a helpful chart of the explicit suggested TOK connections from the IB Biology subject guide.

Case Studies & Provocations

Here are some ideas for connections to the Biology course, either as case studies or simple provocations that can engage students. Many of them basically boil down to the issue of the scientific method and how we decide to act upon (or ignore) scientific evidence. If you find them useful, or have suggestions for improvements, please let me know in the comments.

“Just a theory?”

  • Evolution, natural selection, the nature of science (and falsifiability) and that tired old saying.

Ode to a Flower. Click for lesson.

Ode to a Flower

  • Richard Feynman on his discussion with an artist friend. Who sees the beauty of the flower?

Wade Davis – “The Plants Talk To Us

  • Outstanding TED Talk stimulus. How do tribal shamans work out which combinations of plants give the correct effects without endangering their lives?

Michael Specter – The Dangers of Science Denialism

  • “You have the right to your own beliefs but not your own facts.”

Homeopathy and Oxygen Water (science or pseudoscience)?

  • By what criteria should a claim be judged to be ‘pseudoscientific’?

Facebook Gives You Cancer

  • Media manipulation of low-quality evidence. Over-reaching conclusions.

Altruism and Selfish Genes: Is Anyone Really ‘Good’?

  • Are we truly unselfish or is kindness a veneer to promote our own reproductive fitness?

Sam Harris: Science Can Answer Moral Questions

  • “How have we convinced ourselves that there is no moral expertise; that every opinion has to count?”

The Most Gullible City in Australia

  • Australian comedy show pranks media outlets, testing their willingness to fact check. Funny, but an indication of the poor standards of ‘be first’ churnalism that we see all too often.

HIV and AIDS: Dangerous Denialism

  • To some it doesn’t matter how right you are, but how loud you shout. Sadly. 

What’s the worst that can happen?

  • Rationalism, scientific thinking and climate destabilisation.

  2. Stephen;

    I really appreciate your stuff. Thanks for being such an encouraging colleague and sharing so freely. If my students do well it will be in large part to your direct conrtribution. If they do poorly then I must be filtering too much of your stuff! 🙂

    Thanks so much!

  3. Thanks for all of this great material, particularly the options. It’s our first cohort for IB and we finish in early April. Your help has been fantastic.
    Mike

  4. I would not have made it through my first year teaching at an international school AND IB without your help! It is very obvious that you love what you do and really try to make the material relevent to the students’ lives. It is an inspiration!
    Thanks so much!
