Instructional Ideas
- Use overhead transparencies for students to plot their models for their chosen cities, then place them all together to see how latitude affects length of sunlight
Classroom Considerations
- It's possible that pupils may already know some of the answers to the leading questions from an Earth Science course
- In addition to understanding period and amplitude, high schoolers also need to know how to make scatter plots on a graphing calculator
Pros
- Teacher's guide has more suggestions for modeling with trigonometric functions
Cons
- Internet access is suggested, not required, but some of the questions on the worksheet require learners to access a particular website
- Nonstandard notations for a.m. and p.m. are used in the data table
