Honors BIO Day 4
Osmosis Lab Day
The main purpose of the class today was to be able to take a crash course in Osmosis and then perform a lab to achieve a deep understanding of it. We began the class by taking a short quiz on water and then dove straight into the concept of Osmosis.
Mr. Quick taught with a diagram of NaCl in a glass of water and showed the semi-permeable membrane on the NaCl that allowed the water to diffuse into the cell. He then explained that if the cell became too full of water it would burst, otherwise it would just continue to fill up forever without ever stopping which is impossible.
After the crash course in Osmosis and Diffusion Mr. Quick gave us an overview of what we were to accomplish in the lab. He demonstrated by creating a "cell" and filling it with fructose and then tying it off at both ends. Overall, the lab was extremely stressful because we were constantly struggling against time restraints; however, in the end we managed to complete lab and uploaded our data to the class data folder. David Lee then came back at night and took the data from the Potato and Sports Drink portions of the lab that we were unable to take data on during class.
