Teacher's field guide

What Students Need to Do: Students draw or build a model showing where reproductive hormones come from and where they act. They use arrows to explain how hormone changes affect ovulation, the uterine lining, and sperm production.
What Mastery Looks Like: Their model shows FSH and LH traveling from the pituitary to the ovaries or testes. They show an LH surge triggering ovulation, and FSH and testosterone supporting sperm production. They show estrogen building the uterine lining and progesterone helping maintain it.
Common Misconceptions: Students often place FSH and LH in the ovaries or testes instead of the pituitary. They may think progesterone triggers ovulation or that testosterone alone controls sperm production.
How to Assess It: Exit ticket: Draw one arrow chain from the pituitary to an ovary and another to a testis. Label the hormones on each chain and write one effect of each.

Lesson moves

Give groups pituitary, ovary, testis, and hormone cards; have them connect sources to targets with string and label each effect.
Ask students to write: What changes after an LH surge, and which hormone then helps maintain the uterine lining?
Play a card sort: match FSH, LH, estrogen, progesterone, and testosterone to their sources and effects, then correct mismatches.
Show a printed ovulation test result and have students explain why a positive LH test can predict ovulation.
