This detailed lesson has been written to cover the part of specification point 6.4.3 of the AQA A-level Biology specification which states that students should be able to describe how the structure of the nephron allows for the formation of glomerular filtrate. The aim of the design was to give the students the opportunity to discover the function of ultrafiltration and to be able to explain how the mechanisms found in the glomerulus and the Bowman’s capsule control the movement of small molecules out of the blood plasma. Key terminology is used throughout and students will learn how the combination of the capillary endothelium and the podocytes creates filtration slits that allow glucose, water, urea and ions through into the Bowman’s capsule but ensure that blood cells and plasma proteins remain in the bloodstream. A number of quiz competitions are used to introduce key terms and values in a fun and memorable way whilst understanding and prior knowledge checks allow the students to assess their understanding of the current topic and to challenge themselves to make links to earlier topics. The final task of the lesson challenges the students to apply their knowledge by recognising substances found in a urine sample that shouldn’t be present and to explain why this would cause a problem

This lesson has been written for students studying on the AQA A-level course and ties in nicely with the other kidney lessons on the structure of the nephron, selective reabsorption and osmoregulation
