2 2 8 Perform A First Hand Investigation Using The Light Mic

Method:
- The diameter of the LP field was determined using a grid
- A diameter of the HP field was calculated
- A prepared slide of blood cells was observed at HP, and the diameter of red blood cell and white blood cells estimated
- Diagrams of each were drawn.
- Red blood cells: 6-8 microns
- White blood cells: 7-21 microns

Results:
- Red blood cells are generally smaller than white blood cells
- Red blood cells appear biconcave, while white blood cells usually appear disk shaped, and are spherical
- Red blood cells have no nucleus, while white cells have a darkly staining nucleus
