Food Absorb, Food Digested

Problem--> What brand of dry cat food will be will have the most food digestion and absorption?

Hypothesis--> The most expensive brand of dry cat food used will have the most food digestion and absorption.

Procedure-->
 * 1) Collect materials.
 * 2) Label the large beaker stomach and the other four beakers the brands of cat food you are using.
 * 3) Pour the 1200ml of hydrochloric acid into the large beaker.
 * 4) Add tap water until it is the right pH (a pH of 2), using the pH paper to make sure.
 * 5) Pour the mixture of hydrochloric acid and water into the other four beakers (300ml in each one.)
 * 6) Put about 150 grams of cat food into each of the beakers. (one in each beaker).
 * 7) put the beakers aside for the next 12hours.
 * 8) After 12 hours pour the mixture of hydrochloric acid and the water out using the strainer.
 * 9) Pour 300 ml of meat tenderizer into each beaker.
 * 10) Put the beakers aside for the next 12 hours.
 * 11) After 12 hours strain the meat tenderizer out of the beakers.
 * 12) allow the cat food to dry for a day.
 * 13) using whatever food is left as the weight of the "feces", use this formula, % food digested = (Start weight - final weight) / start weight x 100%.
 * 14) Be sure to record any data.

Materials-->
 * 150grams of four brands of cat food.
 * 1200ml of hydrochloric acid.
 * a large beaker.
 * pH paper.
 * four beakers.
 * one measuring cylinder.
 * 1200ml of meat tenderizer.
 * tap water.
