What is the purpose of art? What knowledge can we acquire through art? These questions can be addressed in many ways. In light of all the attention climate science and climate change have gotten, there are many interesting questions that are raised about why scientists have not been more effective in communicating with the general public issues surrounding climate change and why skepticism and inaction are abound. There are many great TOK connections to these issue. There was an interesting work of public art a few years ago that tried to take the issue of melting glaciers and make it real by lugging giant broken off chunks of ice and bring them to the Climate Change Conference in Paris in 2015. I learned of it from a recent episode of the Netflix Show Abstract. This lesson has a couple of minutes from the show along with a worksheet and article. You can download the handouts I have made here along with the episode of the show.
