Instructional Ideas
  • Use the strategies for differentiation as extra credit or extension activities
Classroom Considerations
  • Experiment requires balloons and string; be sure to make these available
  • Assumes basic knowledge of Doppler effect (for understanding redshift/blueshift)
  • This resource is only available on an unencrypted HTTP website. It should be fine for general use, but don’t use it to share any personally identifiable information
Pros
  • Simple experimental setup
  • Virginia teachers will appreciate alignment to the Virginia Standards of Learning
Cons
  • The Student/Teacher Actions section references a resources section, but this section is missing from the lesson; resource is also missing a link to a NOVA video referenced in the lesson
  • Lesson does not include a student worksheet
