Stratospheric Ozone Depletion

Positives

• Drawings and diagrams help illustrate the concepts presented in the video and the interactive questions can help students check their understanding.
• It connects the health implications of ground-level ozone and the depletion of stratospheric ozone to human activities that we can change.
  

Additional Prerequisites

• You may want to introduce students to the Montreal Protocol, which limited the production of ozone-damaging substances and saved the planet from extreme UV radiation damage.
  

Differentiation

• Philosophy or English language arts classes could discuss how ozone is helpful when it is in the stratosphere and dangerous when it is in the troposphere. Students could write about something else that has the power to harm or help organisms, depending on variables such as time, place, amount, or application. 
• Chemistry classes could discuss the chemical reaction that occurs when nitrous oxide and volatile organic compounds are exposed to ultraviolet light.
• Other resources on this topic include this American Lung Association article on ozone's effect on lung health, this experiment from the EPA on testing for tropospheric ozone, and this Vox video about the ozone layer.
