How to Visualize One Part Per Million

|
Ask a Question

Synopsis
  • This video from TED-Ed shows nine ways students can visualize measurements in parts per million, considering it is not inherently simple to conceptualize. 
Teaching Tips

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).
Scientist Notes
The video provides nine clear examples for students to understand ppm which is a common unit for measuring CO2 concentrations. There is no contradiction in the examples given. Thus, the resource is recommended for teaching.
