Lab-Aids:‚ Blood Smear Kit
This three-step experiment provides students with a clear understanding of lab techniques and an opportunity for self discovery. Students draw samples of their own blood with individualized sterile lancets and prepare smears by applying Wright's stain. Using a microscope, they examine the smears to identify different cell types (erythrocytes, polymorphonuclears, eosinophiles, basophiles, lymphocytes and platelets). This experiment can be safely conducted in a single class period. MICROSCOPES ARE NEEDED.
