✓ Lots of AFL tasks and activities
✓ Exam questions and mark schemes
✓ Diagrams to print

This lesson on Hormones is designed for KS4 Science students enrolled in the CIE Cambridge IGCSE Biology 0610 (2023-25) course. This is the third lesson in the topic 14 Coordination and Response.

The lesson recaps previous learning from other linked topics to ensure students have a strong foundation before diving into the material. It also includes concise and easy-to-understand information and a variety of quick assessment for learning tasks to help students solidify their understanding of the topic. There is a strong emphasis on answering exam questions, with examples and the mark scheme included in the presentation.

Objectives:

• Describe a hormone as a chemical substance, produced by a gland and carried by the blood, which alters the activity of one or more specific target organs
• Identify in diagrams and images specific endocrine glands and state the hormones they secrete, limited to: (a) adrenal glands and adrenaline (b) pancreas and insulin © testes and testosterone (d) ovaries and oestrogen
• Describe adrenaline as the hormone secreted in ‘fight or flight’ situations and its effects, limited to: (a) increased breathing rate (b) increased heart rate © increased pupil diameter
• Compare nervous and hormonal control, limited to speed of action and duration of effect
• State that glucagon is secreted by the pancreas
• Describe the role of adrenaline in the control of metabolic activity, limited to: (a) increasing the blood glucose concentration (b) increasing heart rate

This lesson would also be adaptable for all GCSE students (whether AQA, Edexcel, OCR) and great for KS3 Science or as a GCSE revision resource.
