There are few lessons that I enjoy teaching more than ‘Don’t Take Our Voices Away’: A Role Play on the Indigenous Peoples’ Global Summit on Climate Change in my science classroom. In part, because it gives tangible details and a human face to the issue, not just a story of polar bears or talk about temperature. This is missing in a lot of the science curriculum we are provided. Likewise, the voice of indigenous people in the world is something quite absent in our westernized science curriculum, which is maybe not surprising because these voices are also being left out of world decisions. Those points are what drew me to teaching the lesson. I keep teaching it because of how my students respond. They enjoy the structure of the activity, that they have some agency and control in what happens, as they get to take on the roles and make proposals.
