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)
