Materials

The materials required for the science fair project:

-    300g of fresh steak
-    300g of fresh chicken breast
-    300g of fresh salmon steak
-    3 large bowls
-    6 bottles of Coca Cola

Procedure

1.    For this science fair project, the independent variable is the type of meat used - steak, chicken breast and salmon. The dependent variable is if the meat immersed in the Coca Cola beverage will dissolve. This is determined by checking and observing the bowls containing the meat every day. The constants (control variables) are the size of the bowls, the amount of Coca Cola poured into each bowl, the temperature of the environment (which will remain at room temperature) and the length of the experiment.

2.    Clean the 3 bowls and place a piece of steak, chicken breast or salmon inside each of the bowls. Pour two bottles of Coca Cola into each of the bowls. The meat in the bowl must be fully immersed in Coca Cola.

3.    Inspect the meat in each bowl every day to check if the Coca Cola has succeeded in fully dissolving the meat. Record your observations once a day over the next 5 days.
