Lesson Plan: Action of Hormones Science

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to outline the components of the endocrine system and how it functions using specific examples of endocrine glands and the hormones that they secrete.


Students will be able to

  • state that hormones are chemicals that coordinate and regulate responses within the body,
  • state that hormones are secreted by ductless glands called endocrine glands,
  • locate and name examples of endocrine glands in the human body (pituitary gland, adrenal gland, thyroid gland, ovaries, testes, and pancreas),
  • state that hormones travel through the bloodstream and act on target cells/organs in other parts of the body, using GH and adrenaline as examples.


Students should already be familiar with

  • the concept that the nervous system is involved in sending electrical messages from sense organs to the brain,
  • the fact that hormones cause the changes seen in adolescence,
  • the fact that some hormones are produced by the ovaries and the testes,
  • the fact that some hormones play an important role in the menstrual cycle.


Students will not cover

  • names of adrenal gland hormones except adrenaline (no mention of aldosterone),
  • the thymus and the parathyroid gland.
