The nephron and osmoregulation

2 hour long lessons covering the following learning objectives:

• the roles of the hypothalamus, pituitary and ADH in osmoregulation
• the different parts of the nephron and their roles, including:
• Bowman’s capsule as an ultrafiltration unit
• convoluted tubules in selective reabsorption of glucose, sodium ions and water
• the roles of the adrenal cortex, convoluted tubules and aldosterone in the reabsorption of sodium ions

Designed for a Y12 applied science class (AQA Level 3 Applied Science for Unit 4: The Human Body). It could also be used for a higher ability KS4 class for GCSE biology or A-level biology.

Every activity is fully differentiated. Largely student lead. Help sheets and all activites are included.

L1 tasks: starter to recap on diffusion, think-pair-share activity, intro to nephron, video task with corresponding differentiated question sheet, nephron jigsaw, plenary exam question and mark scheme.

L2 tasks: Big question on urine production, label the nephron activity, think-pair-share, intro to osmoregulation and how its controlled, negative feedback loop task with hint sheet available, differentiated written task and peer-assessment answers, info selection task on sodium ion reabsorption, key word plenary.
