Instructional Ideas
  • Facilitate a discussion on how the ear works to receive sound
  • Bring in a stethoscope and determine how it works
Classroom Considerations
  • Instructions for making the testing device suggest using a metronome in a padded box; if a metronome is not available, another adjustable device that makes sound will work
Pros
  • Lists times for each section of the activity
  • Includes questions for the teacher to ask the teams about their designs
Cons
  • None
