Slight change in experiment title and aim

Due to feedback from my Science teacher Ms Tan Beng Chiak, I decided to modify my experiment title and aim slightly. This is so that I can make use of data collected from set-ups in experiment 2 which used root beer.

New details of experiment 2 as well as report

Research question: What is the effect of phosphoric acid used in soft drinks on meat?

Hypothesis: Phosphoric acid used in soft drinks is unable to breakdown or significantly alter the structure or appearance of a small piece of meat within a short time frame of 48 hours.

Independent variable: Type of solution pieces of meat are placed in

Dependent variables: Mass, total surface area, overall structure and appearance of pieces of cooked and raw meat

Constant variables: Amount of solution used in each set-up, duration of experiment, place where experiment is conducted, time when experiment is conducted, approximate size of pieces of meat, temperature of solution, shape of container (as long as pieces of meat are able to be fully submerged in the solution, the container qualifies) pH of solutions, type of meat used(meat pieces must be compared with others of the same type), condition of meat-cooked or raw(meat pieces must be compared with others of the same condition)
