The purpose of this experiment is to investigate if extreme temperatures kill bacteria more effectively, especially so if the bacteria is exposed to extremely high temperatures (as opposed to extremely low temperatures).  

Instructions preview
1. The independent variable of this experiment is the temperature of storage of the bacteria. The dependent variable of this experiment is the number of bacteria colonies killed. The few constants in this experiment include: the amount of bacteria used, the type of blood agar used and the length of time used. 2. Make 70% turbidity suspension in the normal saline solution for each different bacterium. 3. Separate one solution of bacteria between 30 vials, with 250 micro liters per vial. 4. Choose 5 of these vials and label them according to their names, their temperature of storage, and .....
