What time should school start in the morning? The circadian rhythm is a 24-hour cycle that regulates how a body feels. As humans get older, the rhythm changes...which often leads to conflicts between parents and their sleep-deprived teens.

Students use periodic functions to compare the alertness levels of adults vs. teenagers over the course of the day and debate the merits of starting school later.

REAL WORLD TAKEAWAYS

  • Humans beings’ alertness changes throughout the day because of their natural circadian rhythm.
  • A typical teenager’s circadian rhythm is shifted from an adult’s. Teenagers experience peak alertness later in the day.
  • The typical work day matches adults’ peak alertness; the typical high school day does not match teenagers’ alertness.

MATH OBJECTIVES

  • Identify key features of a graphed periodic function including: period, amplitude, and relative maximums and minimums
  • Interpret a trigonometric function modeling a real-world phenomena and use it to justify decision-making

This complex task is best as a culminating unit activity after students have developed formal knowledge and conceptual understanding.
