How Are Bacteria Identified? Lab Activity

Simple, Student-Directed Science Activity

Learn to characterize bacteria as positive or negative through Gram staining. The differences in bacterial cell morphology will result in staining of bacteria as pink (negative) or blue (positive). Based on this result, the correct antibiotics can be prescribed by a physician to fight human bacterial infections. A basic microscope with 100X magnification is required to view complete bacterial morphology. Includes materials for six experiments. All experiments are created and classroom tested by teachers and science education experts. Each kit includes an experiment guide with background information, procedures, safety recommendations, and an evaluation quiz.
