GCSE Biology: Hormonal control (including non-communicable diseases)
Hormones and hormonal control is an abstract concept which many GCSE Biology students struggle with: students often appear to be misinformed about what hormones are and what here role is. It is worth spending some time giving an overview of the endocrine system and then allowing the opportunity for some independent study with students completing set tasks to research about individual hormones and their actions. This research can then be assesed to ensure students fully understand the action of different hormones
Students find it particularly difficult to explain each stage of the menstrual cycle and the role each hormone has. Understanding the role of the various hormones in the menstrual cycle will then enable them to explain how hormonal contraceptives work and evaluate hormonal and non-hormonal contraceptives. Students also need to be able to explain the use of hormones in modern reproductive technologies to treat infertility.
For this topic students need to be able to explain the concept of negative feedback with examples of the action of specific hormones, in particular adrenaline and thyroxine.
