What it is
- This video explains the connection between global warming and the ozone hole, chemical build-up in our lower and upper atmospheres, increased GWP gases, increased air quality ozone alerts, and the 1987 Montreal Protocol that banned the use of CFCs globally.
- Students will learn about the history of the ozone hole and the efforts to help protect the ozone layer.
Teaching tips
Positives
- The video includes helpful animations to keep students engaged and ends on a positive note.
- The narrator presents information clearly and with a conversational tone.
Additional Prerequisites
- The video mentions Earth's poles, so teachers may wish to have a globe in the classroom to use as a resource.
- Teachers can share this information via social media or embed the video as a link within a lesson plan.
- Because the vocabulary is somewhat rigorous, a definition list will be helpful.
- It may benefit students to know about greenhouse gases, the greenhouse effect, and chemical notation.
Differentiation
- Science teachers can pause the video and have students take notes about the history of CFCs, their effect on the ozone layer, and the different layers of the atmosphere.
- The UN is mentioned, along with the terms "Montreal Protocol," "ratification," and "treaties," so Social Studies teachers can utilize the lesson when discussing the need for the United Nations.
- Students can discuss the influence of carbon emissions on global warming and the poles' recovery and can research solutions for reducing emissions.
- Some students may benefit from guided notes and slowing the video playback speed.
