Natalia Wierzchon A.P. Biology Lab: 1. Osmosis 09/10/2010 I. Introduction a. Purpose: The purpose of this lab was to observe the diffusion process of water‚ osmosis‚ as well as create an understanding of water potential‚ the basis of osmosis. The experiment proved how water molecules in a solution are able to move from an area of low solute concentration‚ high water concentration‚ to an area of high solute concentration‚ low water concentration‚ diffusing “down” the water gradient.

theories is Skinner’s Operant Conditioning in which an element of reinforcement and punishment is utilized to shape the child’s social and behavioral skills. It will be the parent’s job to reinforce wanted behavior and punish unwanted behavior. For example‚ if the child throws a temper tantrum‚ her parents might put her in time out to show that this type of behavior is not acceptable. The punishment therefore reinforces that if she acts this way again‚ she knows she will be placed in time out. Essentially

it was not until my first test in AP Biology‚ that I realized I actually had to go the extra mile and put forth maximum effort into studying and reviewing. I needed a biology mentor like Mrs.Ciasulli to bring out the best in me because she knew of my aspirations to work in the medical field. Although she attempted to make my life as difficult as possible‚ she made me fall in love with the material and gain much more appreciation for the study of biology. AP Biology then became the class I was most
