The hypothesis is that extremely high temperatures will kill more bacteria than extremely low temperatures.

You will make a turbidity suspension in normal saline solution for each different bacterium, separate the solution between vials, label them according to their names and temperatures, store them at the respective temperatures, and then count the number of bacteria colonies killed.

You will need 7500 micro liters of Bacillus Cereus, Clostridium Perfringens, Mycobacterium Tuberculosis, and Salmonella, cotton buds, normal saline solution, 120 vials/test tubes with stoppers, 120 Petri dishes filled with blood agar, a box of disposable plastic pipette tips, a 10 micro liter pipette, a 250 micro liter pipette, a calorimeter, goggles, and a lab coat.

The results of this experiment showed that extreme high temperatures killed more bacteria than extreme low temperatures. This information is important for scientists to develop effective methods for killing harmful bacteria.

This science project is interesting because it explores the effects of extreme temperatures on the growth of bacteria, which is an important factor in understanding how to prevent contamination.

Variations of this experiment could include studying the nature of the bacteria used in the experiment and exploring other alternatives to kill bacteria.
