My purpose is to show that the bacteria content does increase in a water bottle when it is not properly washed between uses. In the summer during swim team, I see my teammates fill the same water bottle every day for the whole season.

Although we can't always see them, microorganisms are present in almost all environments. Many can be grown in the laboratory on plates containing a solid, nutrient-rich medium (agar plates). After several days, a single bacterial cell grows into a population of bacterial cells that is visible to the naked eye. This population of cells is called a microbial colony. In this exercise we will test fo

The purpose of this experiment was to compare the bacterial content before and after the use of Clorox wipes on the inside and outside door handles of restrooms. I became interested in doing a project on bacteria because I am interested in a career in medicine, biology or microbiology. In addition my mom has taught me about avoiding bacteria in restrooms and encouraged me to use a paper towel
