As a Chemistry teacher candidate, my ToK subject presentation was related to Chemistry, and more specifically, the atomic structure. I would use inquiry to introduce the atom to the class and we would come up with the Bohr model together. Leading up to the ToK discussion, I would introduce the atomic bombing in Hiroshima-Nagasaki and ask them if the idea had not been developed and shared, would that have occurred? Then I’d make them think about the ethics and responsibilities involved with education, knowledge and the power it holds. Thus, if you have knowledge, is it your responsibility to pass it on? Is it ethical to work on something that is potentially harmful? Whose responsibility is it to control the outcome of an experiment especially if it is harmful?
