How to Visualize One Part Per Million

Positives

• The video was created with the help of over 100 animators to create visualizations of one part per million.
• The examples used are engaging, relatable, and varied which can make it more accessible to different styles of learning.
• The video webpage includes eight "Think" questions, a "Dig Deeper" section with additional resources, and a "Discuss" section with a guided prompt for discussion.

Additional Prerequisites

• Students should know what types of things we measure using parts per million, particularly greenhouse gas concentrations.
• Students should understand that even though one part per million seems small, even low levels of toxic substances are dangerous.
• You must sign into the website to use the interactive features.
  

Differentiation

• Students can create their own analogies to visualize one part per million.
• Students in math classes can convert units using parts per million.
• Students can write an analysis of why they think it is difficult for humans to conceptualize parts per million and relate it to why humans have a hard time conceptualizing long periods of time (like the 4.6 billion years of Earth's history).
