Osmosis

Rationale: Standard seven means that I have the ability to to plan my instructions with being being able to meet every students needs. The artifact I have selected for standard seven, is the Osmosis Lesson Plan. I selected this artifact because it reflects on the different adaptions and modifications I would have set up for my students within one lesson for that subject. Another reason why I chose this artifact is because I was able to provide my students with a hands-on science lab, while being…

Results and Discussion A. Diffusion of selected plant pigments In conducting the diffusion of 4 different kinds of treatments (distilled water, distilled water placed in boiling bath, vegetable oil, heated vegetable oil), the researchers made use of the atsuete and sugar beets. The different kinds of treatments determined how the temperature will affect the color intensity of the atsuete and sugar beets. There were 4 test tubes used in each atsuete and sugar beets with each having a…

Conclusion The overall results support the hypothesis. The experiment involved soaking 20mm (±0.5mm x 2) apple cores in 10cm3 (±0.5cm3) of saline solutions in 0%, 1%, 3%, 5% and 7% concentrations for 1800s (±0.3s (human error)) and comparing the initial masses (g±0.01g) with their masses after soaking (g±0.01g). There was an outlier in the 13% mass change of the apple core after soaking in 7% saline solution, as shown in Graph 2. However, this outlier and the general trend of the data support…

Purpose This lab’s purpose was to experiment how much of a syrup solution would seep through a dialysis bag at different temperatures. Procedure We prepared by filling up three dialysis bags with about 100 mL of a syrup solution. We tied knots on either end and measured the initial mass of the bags. The bags were measured in grams. Then we added water to three different beakers, each being a different temperature. One beaker was room temperature, another was heated to about body temperature…

Moreover, homeostasis is significantly important to the cells of the body as these rely on the movement of chemicals. Chemicals that need to be sent in out out of cells are oxygen, dissolved food and carbon dioxide; this being performed by osmosis and diffusion. Also, osmosis and diffusion rely on the balance of the bodies water and salts, this being another aspect that is maintained by homeostasis. However, the cells rely on enzymes to make the chemical reactions that occur within the body, to…

When osmosis is applied, it dictates that the movement of water across cell membranes and the balance of water between the cell and its environment (Reece et al., 2011). On the first experiment of the effects of Osmosis on Potato cell, the plain potato was compared with a potato that had salts on. The plain potato was the negative control, and it changed to brown…

a process that seeds undergo when the correct exterior conditions are met and water is introduced, allowing seeds to begin the process of growing into a fully mature plant. When enough water is near the seed it enters the cell by osmosis, specifically a type of osmosis called imbibition when the seeds are in a dormant state. The flow of the water into the seed reinstates a hypotonic environment.This recreates turgor pressure inside the cells causing the cell walls to be rigid, the cells to…

Water purified by means of reverse osmosis, and other demineralizing procedures is not healthy for human consumption, and the distribution of this water is unethical because of these health issues. It turns out that the purification of water removes vital nutrients and minerals, not just the toxins in the water. Water purified by reverse osmosis is in fact water in its purest form, almost 100% H2O, but that does not make it healthy for the human body, which requires minerals which…

character who is at one with self and country. the African-American females of A Raisin in the Sun give a firm, plain vicinity. Their attention on the quest for home and character is to a great extent interior or social, instead of the manly examples of osmosis and securing. Rather, these homemakers…

Previous scientists have found that placing a gummy bear in water will result in the largest increase of size. Other liquids can affect the size of the gummy bear, but not as much as water. When the gummy bear is placed in a cup of water, osmosis takes place. Molecules from the water in the cup go through the semi-permeable membrane of the gummy bear. The molecule smove from the less concentrated solvent into the higher concentrated one. The molecules of water in the cup become crowded…
