9/7-9/8 Lab

We learned about the digestion system and stomach. The materials we used were a test tub rack, pepsin, water, 4 strips of litmas papers, boiled eggs, graduated cylender, hydronic acid and 4 test tubes with stoppers. We used the eggs as the meal, and the hydronic acid as hydronic acid. We used the beakers for your stomachs in our body. So all in all we put the eggs in the bakers and added acid to some of the beakers and we used enzymes in the beaker too. The next day we found out that the digestion system takes a long time because our eggs had not digested all the way.
