Introduction to Microscopy

Learning Goal: To compare the different types of microscopes and understand their limitations.

Introduction: Telescopes, magnifying glasses, and other types of lenses have been in use for centuries, especially in the sciences. Early microscopes used visible light to look at objects. These early scopes and light microscopes of today have an effective magnification range up to about 1,000 times, or 1000x. For magnifications higher than 1000x, an electron beam is utilized to illuminate the specimen. Thus, the two basic types of microscope are referred to as light microscopes and electron microscopes.

 

Identifying Bacteria through Staining

Learning Goal: To learn how microbiologists identify different types of bacteria through staining.

Introduction : Under a powerful light microscope, it’s possible to see something as small as a single bacterium. However, different types of bacteria can look very similar even at high magnification. In such cases, scientists use a variety of stains to tell types of bacteria apart. This technique is called differential staining. In this activity, you will observe how different types of bacteria appear when stained using this technique.
