Active learning ideas
Hormonal coordination introduces the endocrine system as a slower but longer-lasting alternative to nervous control. Students learn about the major glands, including the pituitary, thyroid, adrenal, and reproductive organs. The curriculum emphasises how hormones are secreted directly into the bloodstream to reach target organs. This topic is vital for understanding how the body manages growth, metabolism, and reproduction over extended periods.
Activity 01
Set up stations around the room for different glands (Pituitary, Thyroid, Pancreas, etc.). At each station, small groups must identify the hormone produced, its target organ, and its primary effect before moving to the next.
What is the endocrine system?
Activity 02
Divide the class into two teams representing the two control systems. They must argue why their system is more 'efficient' for specific scenarios, such as pulling a hand away from a flame versus regulating puberty.
How do hormones travel through the body?
Activity 03
Students are given a diagram of the circulatory system and must trace the path of a hormone from the pituitary gland to the kidneys, explaining why it doesn't affect the heart on the way.
What are the key differences between nervous and hormonal control?

A few notes on teaching this unit
Watch Out for These Misconceptions
Hormones only affect the reproductive system.
Students often associate hormones solely with puberty. Using a gallery walk of various hormones like thyroxine and adrenaline helps them see that the endocrine system regulates almost every metabolic process.
Hormones travel through specific 'hormone tubes'.
Clarify that hormones use the existing circulatory system. Peer explanation tasks where students map the blood flow help reinforce that hormones are broadcast to the whole body but only 'unlock' specific target cells.
Methods used in this brief
The Human Nervous System
An investigation into the structure and function of the nervous system, including reflex actions and synapses. Students will understand how electrical impulses coordinate rapid responses.
8 methodologies
Controlling Blood Glucose
Students examine the roles of insulin and glucagon in regulating blood sugar levels. The topic also covers the causes and treatments of Type 1 and Type 2 diabetes.
