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.

Chicken Wing Green Class

One thing i learned from the chicken wing experiment is that the chicken wing was just like the human arm. One way it is the same as the arm is that both have muscle and bone that move the part. We also learned that the chicken wing also has muscle just like the human arm. We also now know that the wing has bone just like the arm. We also know that the chicken has ligaments in the wing just like the arm. Those were the facts that stud out to me the most because they were the ones that we most like the human arm.

Science Green Lab 10/11/11

I learned that when you mix the solution in the beaker ( iodine) and the solution in the bag (starch) the starch turns purple but the iodione stays orange. Also i learned that even though the cell membrene controls what goes in and out of a cell little things can still get in. Also I learneed that starches are kept in the cell.
