This science fair project aims to discover which type of processed poultry meat possesses the largest amount of bacteria. This experiment will be conducted using meat from a fresh chicken, irradiated chicken and frozen chicken
1. The independent variable for this science fair project is the type of processed chicken meat – fresh, frozen and irradiated. The dependent variable is the size of the bacteria growth in the Petri dish. This is determined by measuring the size of the bacteria growth using a ruler. The constants (control variables) are room temperature, the amount of sunlight and the ingredients in the Petri dish agar. 2. Prepare 3 Petri dishes using agar and store them in a refrigerator. The Petri dishes are brought to room temperature before the start of experiment by taking them out of the .....
