Instructional Ideas

  • Use the resource as an example of the relationship between pressure and temperature
  • Get the class thinking by showing only the first part of the video, then have them explain what conditions the physicist must control to create identical snowflakes
Classroom Considerations

  • For younger learners, a quick discussion of the properties of water will help them understand how flakes form

  • Time lapse sequences allow students to watch as a snowflake grows and changes
  • Animations help illustrate the movement of water molecules at high altitudes as they react to changes in pressure, temperature, and concentration

  • None
