| Lesson Topic: recognise and draw red blood cells, monocytes, neutrophils and lymphocytes from microscope slides, photomicrographs and electron micrographs |
Learning Objective/s:
- Identify and differentiate RBCs, monocytes, neutrophils, and lymphocytes using light, photomicrograph, and electron microscopy.
- Describe the key morphological features (size, nuclear shape, granule pattern) of each cell type.
- Accurately draw each cell with correct proportions, labeling, and a scale reference.
|
Materials Needed:
- Light microscope with calibrated eyepiece micrometer
- Prepared blood‑smear slides
- Printed or digital photomicrograph and TEM images
- Whiteboard and markers
- Worksheet with identification checklist and drawing templates
- Projector for displaying images
|
Introduction:
Begin with a quick visual poll of students’ favourite blood cell to spark interest. Review prior knowledge of basic blood components and the role of microscopy in cell identification. Explain that today they will master recognizing and drawing four key blood cells, with success measured by accurate sketches and correct labeling.
|
Lesson Structure:
- Do‑now (5'): Students label a mixed‑cell image worksheet individually.
- Mini‑lecture (10'): Review morphology table and microscopy techniques, highlighting distinguishing features.
- Guided practice (15'): Whole class examines LM slides and digital images, using the checklist to identify each cell type.
- Paired drawing activity (15'): Students sketch each cell on a template, focusing on shape, nucleus, granules, and scale bar; teacher circulates for feedback.
- Peer review (10'): Pairs exchange drawings, assess accuracy with a rubric, and give constructive comments.
- Whole‑class recap (5'): Teacher summarises key cues and answers remaining questions.
|
Conclusion:
Summarise the three visual cues—size, nuclear morphology, and granule presence—that differentiate the cells. Have students complete a quick exit ticket listing one distinguishing feature for each cell type. Assign homework to practice drawing the cells from provided photomicrographs and upload a scanned version before the next lesson.
