Chicken Wing

On Thursday our science class dissected a chicken wing.  We learned the diffrent parts in a chicken wing, what color they are how they feel, etc.  My favorite part of the chicken wing were the tendons.  The tendons were shiny and white.  The tendons were at the end of the muscles that attached the muscles to the bones.  It was sooooo cool when our science teacher pulled on the tendon and the bones moved.  I thought it was freaky but also cool.  The part that I thought was disgusting was the fat.  The fat was yellow, and it was under the skin.  EEEWWWW!  The reason we did this lab was so we could see how human's arm work.  Other terms we learned were; Cartilage, Ligament, Muscle, and Skin.  Not only did we learn these terms but we also learned what color they were,the texture it had etc.

Diffusion Lab

Today in science class I learned new words such as diffusion and osmosis.  I also learned that if you put a bag of starch mixed with water into a beaker filled with water and iodine the bag of starch and water turns purple after 15 minutes.  In the beginning when we put the baggie into the water/idoine the water was orange but grudually changed color.  From this lab i learned an intresting fact, that molecules don't like to be crammed togather they want to move around freely.  An example Mrs. Rousseau gave was that if she put all of Omega and Chi in the science room everyone will be crammed together.  When she opens the room people will start to drift out, this is the same with molecules.  I also learned that the plastic bag was permeable to iodine since that was what the lab thought us.
