As The Stomach Churns Lab: Part 1: Day 1

In class, we did a lab using egg whites and hydrochloric acid. We had four test tubes, A. B, C and D.
Each test tube had three pieces of egg whites. We also put something different on top of the egg whites in each test tube. In test tube A, we put 10 mL of enzyme pepsin on top of the egg whites.  There was no immediate reaction in the egg white appearance. In test tube B, we put 5 mL of water, and 5 mL of pepsin. The egg whites started bubbling. In test tube C, we put 10 mL of hydrochloric acid. There was no immediate reaction. In test tube D, we put 5 mL of hydrochloric acid and 5 mL pepsin. The egg white was melting slowly. We then took stirrers then put them in each test tube then on to blue litmus paper. Test tube A solution, there was no immediate reaction. Test tube B solution, the litmus paper gets wet. Test tube C solution, the litmus paper turns pink, because when the hydrochloric acid touches blue litmus paper it turns pink. Test tube D solution, turns pink and for the same reason.

Chicken lab: Class Response

The chicken lab showed us how bones, blood vessels, and organs work. When Mrs. Rousseau pulled one muscle the other one relaxed. When one muscle contracts the other relaxes. Nervous tissue carries messages back and forth between the brain and every other part of your body. Mrs. Rousseau cut off the skin and then through some muscle and then blood came out because she cut through a blood vessel. Then Mrs. Rousseau cut the top of the bone off and then showed us the bone marrow.

OKAY, THIS IS JUST WEIRD. I MEAN, I DIDN'T EVEN READ IT, BUT I CAN TELL THIS IS WEIRD JUST BY THE TITLE.

Class Response: Diffusion Lab

The diffusion lab was not a success because the corn starch did not turn dark purple when the iodine was put in the beaker.  Mrs. Rousseau put some more iodine in the beaker and as we waited about fifteen minutes. After fifteen minutes we pulled out the bag and the bottom of it was dark purple. The reason this lab did not work is because the plastic bags were too thick and did not allow in the iodine with the corn starch. I think it would have worked if we poked a small hole in the bag and let some of the corn starch out into the beaker. 

DRUNKEN MOOSE ENDS UP IN STUCK IN SWEDISH APPLE TREE

I didn't want to show the picture because it was quite disturbing but for anyone who wanted to see it:

Apparently, the moose got drunk on fermented apples, and in the autumn there is always at least one case of intoxication.

A Giant panda dies at the Chinese Zoo, at age 34.  The name of the panda was Ming Ming, and she had kidney failure. Giant pandas are among the worlds most endangered species list with about 1600 in the wild, and there are more than 300 captive in China most for breeding to help boost the Giant Panda population. On average, wild pandas live up to 15 years, and the ones in captivity live up to 22.

5/17 Science Blog: Are coffee drinkers less prone to aggressive breast cancer?

http://health.yahoo.net/news/s/hsn/arecoffeedrinkerslesspronetoaggressivebreastcancer


I think that it is amazing that drinking coffee can reduce the amount of breast cancer. Before, there was no cure for breast cancer, and then just by some swedish women, there is a way to reduce breast cancer. It is not a cure, but I am almost sure that scientists will figure out a cure for breast cancer, by using the discovery that coffee reduces breast cancer. I think the key is to find out what kind of coffee reduces breast cancer and to find out which ingredient in particular reduces the chance of breast cancer. Sooner or later, I know that there will be a cure for breast cancer.
