What Ever Happened to the Hole in the Ozone Layer?

Secondary

Description

Around 30 years ago, scientist found a massive and growing hole in the ozone layer. How is it doing today? This video presents a quick and concise overview of the ozone layer - what it is, what caused the thinning of the ozone layer, the international response to that thinning (Montreal Protocol), and the current state of the ozone layer.

The video subscript is that the lesson learned from the ozone layer story has relevance for the current debate over climate change.

General Assessment

What skills does this resource explicitly teach?

In order to benefit from the viewing of the video, students must practice those listening skills that help them recognize the main idea and the supporting evidence. 

Strengths

While the ozone layer is no longer in the headlines, the response to the thinning of the ozone layer, as represented by the Montreal Protocol, is instructive, in that it illustrates what can be done when the international will is there.  

Recommendation of how and where to use it

What Ever Happened to the Ozone Layer? may be part of those resources used to study climate change. Students may explore to what extent the story of the ozone layer thinning provides a useful parallel in responding to the current challenge of climate change. 

The video also may support the teaching of chemistry units dealing with environmental chemistry and atmospheric gases
