| Lesson Topic: Identify, in diagrams, photomicrographs and electron micrographs, the parts of a nephron and its associated blood vessels and structures, limited to: glomerulus, Bowman’s capsule, proximal convoluted tubule, loop of Henle, distal convoluted tubule, c |
Learning Objective/s:
- Identify the glomerulus, Bowman's capsule, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct in diagrams, photomicrographs and electron micrographs.
- Explain the functional relationship between each nephron segment and its associated blood vessels.
- Compare structural adaptations of each segment to its role in urine formation.
- Apply knowledge to label a schematic nephron diagram accurately within a timed assessment.
|
Materials Needed:
- Projector and screen
- High‑resolution nephron diagrams (schematic, photomicrograph, electron micrograph)
- Printed worksheets with unlabeled nephron diagrams
- Whiteboard and markers
- Laptop with image annotation software (e.g., PowerPoint)
- Colored pens for student labeling
|
Introduction:
Begin with a quick think‑pair‑share: Where does the kidney filter blood and how is the filtrate modified? Review prior knowledge of basic kidney anatomy, then outline today’s success criteria: students will correctly label six nephron components and explain their vascular connections.
|
Lesson Structure:
- Do‑now (5'): Students label a blank nephron schematic from memory.
- Mini‑lecture (10'): Overview of nephron structure with projected diagrams, highlighting each segment and its associated vessels.
- Guided analysis (12'): Examine a photomicrograph of the glomerulus and an electron micrograph of the PCT; identify key features.
- Interactive labeling activity (10'): Small groups label printed worksheets containing all six segments; teacher circulates for feedback.
- Concept‑check quiz (8'): Quick‑fire Kahoot questions linking hormonal control to specific nephron segments.
- Summary & exit ticket (5'): Students write one sentence summarising how structure supports function for one nephron part.
|
Conclusion:
Recap the main structural‑functional links discussed, emphasizing how each segment’s design facilitates its role in urine formation. Collect exit tickets as a retrieval check and assign homework to create a labeled digital nephron diagram using the provided images.
