LAB REPORT OUTLINE FOR DIFFUSION/OSMOSIS LAB
Introduction: Diffusion is the net movement of small or uncharged molecules or substances from areas of higher concentration to areas of lower concentration. There is simple diffusion, as explained, and facilitated diffusion. Facilitated diffusion, on the other hand, involves larger or charged molecules or substances that need a protein tunnel through the membrane to help the substance enter and leave the cell. Since the substance will move in its direction, diffusion does not require energy. Diffusion helps rid of waste because the waste moves out as well during the process. Once diffusion occurs and the substance is dispersed completely, there is equilibrium. Osmosis is the diffusion of water from an area of high concentration to an area of low concentration. The more dissolved substances a solution has, the lower its concentration will be. …show more content…
Cup #1 should be labeled water, Cup #2 should be labeled salt water, and Cup #3 should be labeled sugar water. Next, select 3 differently colored gummy bears. After you select the color gummy bears that you want, label each cup to indicate which color will go in each cup. Fill each cup half way with water. Then add about 1tsp. of salt to cup #2 and stir. Then add about 1tsp. of sugar to cup #3 and stir. Lastly, place the gummy bears in solution and be sure to match the color that is labeled on the tape. You must wait 24 hours to observe results.
Results:
The original gummy bear weighed 0.08 ounces. After the green gummy bear remained in the water, it dissolved entirely. The red gummy bear that was placed in salt water was no longer transparent and shrunk slightly in size, weighing 0.045 ounces as a result. The yellow gummy bear grew larger and became lighter in color, weighing 0.23 ounces. Each of these gummy bears came out with a jelly-like texture.
