Synopsis
This video from Grist discusses the concept of tipping points, specifically with regard to permafrost melting, melting ice sheets, and Atlantic Meridional Overturning Circulation.
The video uses a glass of water that is slowly tipped to one side until it falls over as a visual representation of ecological tipping points.
This video is brief and does a nice job of simplifying the concept of positive feedback loops and ecological tipping points related to climate change.
Prerequisites
There may be a commercial before the video.
It may be beneficial to activate prior knowledge about the albedo effect, the density of water at different temperatures, and the production of carbon dioxide from cellular respiration and decomposition.
Differentiation & Implementation
Science classes can set up their own model demonstration of a tipping point to illustrate the idea or run an albedo experiment using identical objects of different colors to see differences in temperature increase in direct sunlight.
Social studies classes can discuss the human toll and impacts on societies in various locations if we cross these tipping points.
