Positives 

• The video builds connections between chemistry, history, and civics.
• Professor Grossman highlights the essential role public policy and global coordination played in solving the ozone depletion crisis.

Additional Prerequisites

• The video and transcript are available to download.
• The video on the MIT site does not have closed captioning or subtitles. However, a YouTube version of the video with closed captioning and auto-translate subtitles can be accessed by clicking the YouTube icon in the bottom right corner of the video.
• Some content presented is copyrighted and is not in the public domain or CC licensed.
• Students should already be familiar with absorption lines, the Bohr model, and writing chemical equations.

Differentiation

• This resource is best suited for use in AP, IB, or college chemistry courses and will need additional context or materials to support student learning.
• This video can be used after learning about degradation reactions, catalytic cycles, absorption lines, and/or the Bohr model to illustrate the importance of these topics with a real-world application.
• Teachers will likely need to explain concepts beyond what is presented in the video, especially for the chemical equations and the solar radiation spectrum. Consider playing the video multiple times so students can process the information and identify questions they still have.
