Lesson 2: The Endocrine Orchestrator (Hormonal Regulation)
Duration of Days: 4
Lesson Objective
Analyze the negative and positive feedback loops that regulate the male and female reproductive cycles.
How do hormones "tell time" in the body? What triggers the monthly changes in the female reproductive system?
GnRH, FSH, LH, Estrogen, Progesterone, Testosterone, Corpus Luteum.
HS-LS1-3 (Feedback Mechanisms)
Interpreting complex "multi-line" graphs showing 28-day hormonal fluctuations
Description: Students map the interplay between the brain (pituitary) and the gonads.
Purpose: To understand chemical signaling as a controller of systemic change.
DOK 3.
How hormonal contraceptives "trick" the feedback loop to prevent ovulation.
Thinking that "testosterone" is only in males and "estrogen" is only in females. (Correction: Both sexes have both, in varying concentrations).
Create a "Hormone Role-Play" where students act as the Pituitary, Ovary, and Uterus to demonstrate the signal sequence.
"The Hormone Tracker": Given a set of hormone levels, students must predict which phase of the cycle a patient is currently in.
