Satellite

Curated and Reviewed by Lesson Planet
This Satellite activity also includes:

Learners practice relating rules of trigonometry and properties of circles. With a few simplifying assumptions such as a perfectly round earth, young mathematicians calculate the lengths of various paths between satellite and stations. In a classroom where students likely consider their cell phone as an extension of themselves, finding the many thousands of miles a signal must travel could certainly be surprising.

Instructional Ideas
  • Could be a problem set introduction to a real-life geometry project (calculating dimensions in application)
  • Good open-response practice question for end of course testing
  • Could be done in conjunction with a science lesson on satellites or cell phone signals for a cross-curriculum unit
Classroom Considerations
  • Higher reading level introduction might require ESL support
  • Assumes learners already know how to use Pythagorean's theorem, calculate arc length, use trigonometric ratios, and apply the law of cosines
  • First page worksheet for students has no room for recording answers and calculations 
Pros
  • Challenging but not overwhelming constraints
  • Clearly worked out step-by-step solutions
  • Hints for helping learners avoid common pitfalls
Cons
  • None
