Homeostasis (a steady state)Objectives:
all: know that hormones are chemical messengersMost: know about the role of insulin and adrenaline (and be able to outline differences between nervous and chemical control after the next lesson)Some: report how the hormonal systems are protective of the body
This is work towards: UNIT 5P7 describe two control mechanisms which enable the human body to maintain optimum health.M7 describe the differences between the actions of chemical and electrical protective mechanisms of the body.D7 explain the effects of the chemical and hormonal controls on human health.
Ovaries and testes are responsible for sexual characteristics – give examples of these (e.g. voice deepens in males)
Name the male hormone
Name a female hormone

ExperimentTwo samples of ‘urine’ have been provided from different patients. One of the patients has diabetes.

To get rid of this glucose, diabetics may visit the toilet often, and because they lose water develop an insatiable thirst.
