Which type of meat will tenderize most using cola drinks?
-To help Namibians use a cheaper, easier and always available type of meat tenderizer. Hypothesis:
Beef will tenderize most.
In my research,”Phosphoric Acid”, the main ingredient of cola drinks, is assumed to be of high enough concentration to deteriorate a piece of meat. So in this experiment, I want to prove if cola drinks can tenderize meat and what type of meat can it tenderize most. Plan:

The plan is to come up with my researches and seek help from others. Then, I have to understand every single step from the start until the end, to reach to my conclusions. -Variables
* The independent variable in this experiment is the kind of meat using: * BEEF
* The controlled variables are the following:
* Cola drink’s quantity
* Meat’s weight
* Bowl’s size
Meetings & Discussions:
At first, I researched for experiments that can be done and I ask myself how cola drinks can clean rust and by that I found out that it was because of phosphoric acid. So, that brought me up to the idea of this experiment.
