                                  LEARNING OBJECTIVES:  At the end of the lesson, students will: 1.  Define Culturing 2.  Describe how to prepare a culture solution 3.  List the instruments required and the necessary precautions to be taken in preparing a culture solution 4.  Demonstrate culturing and monitor the growth rate of microorganisms . 5.  Identify colonies of microbes present in different culturing samples. KEY VOCABULARY WORDS:  Culture, Agar, Microscope, Petri-dish, Inoculating loops, Hand lens, Slides etc. Culturing simply involves growing microorganisms in special media in the laboratory. It involves making sterile medium, inoculating, incubating and examining micro-organisms. By this means, micro-organisms' characteristics such as colour, the pattern of growth, and appearance can be seen. -   INSTRUMENTS REQUIRED FOR THE PREPARATION OF CULTURE SOLU...

They exist almost everywhere, in water, air, soil, surface of objects, as well as on and within living organisms.  They are carried by air currents from the earth’s surface to the upper atmosphere. They occur most abundantly where there is food, moisture and adequate temperature for their growth. It was the invention of microscope that opened the gateway to the world of these minute living organisms. The first person to discover microbes was a Dutch man called Anthony Leeuwenhoek (1632-1723). Using a simple microscope, he was astonished to discover that rain water that had been collected from pools was full o...
