What will we be looking at under a microscope in this lab? Bacteria Cells Plant Cells Animal Cells
Specimen Whatever you want to look at under a microscope. (e.g. hair, blood, cells, insects, etc.)
Preparing Microscope Slides: 1. Grab a clean glass slide. 2. Place specimen on middle of slide. 3. Put one drop Iodine (Blue Dye) on top of specimen. 4. Cover specimen with a cover slip. Specimen Iodine

Cheek Cells – Low Power
Cheek Cells – High Power
Purpose of Iodine: Outlines the big parts of the cell such as the Nucleus and Plasma membrane.
Elodea Cell – Low Power
