Description | ||
This science fair project was done to compare the effectiveness of using a Microban polymer-based chopping board and a plastic chopping board, against bacteria growth. | ||
Instructions preview | ||
1. For this science fair project, the independent variable is the type of chopping board used – plastic and Microban polymer based. The dependent variable is the number of bacteria colonies growing in the petri dish. This is determined by observing and counting the number of bacteria “spots” (colonies). The constants (control variables) are the room temperature, the amount of sunlight and the ingredients in the petri dish agar. 2. The 6 petri dishes that have been prepared with agar are stored in a refrigerator. The petri dishes are brought to room temperature before the start of the science ..... |
