Science Diffusion Conclusion

In science there was a lab that I explained already below. This is the conclusion of the lab. The purpose of the lab was to see how the cell works in an animal. The solution in the bag was corn starch; in a beaker was diffusion iodine. The iodine was in water which lowered the concentration. The bag was permeable, and the corn starch could not come out. The corn starch or carbohydrates was white, and the solution was brown. Osmosis is the change of concentration in a solution when you add water or take away water. The hypertonic iodine which means that it was more concentrated, leaked through the bag and changed the color of the corn starch, which is less concentrated or hypotonic, changes color when it revealed by the indicator, the iodine. The iodine is more concentrated then the corn starch but it is still less concentrated the original iodine. What happen was that when water was added to the iodine is lowered the concentrated, this process is called dilution. The prediction of it staying white was incorrect.
During this lab the class had many implications. The implications of the lab were to figure the ways how the permeable bag is like a cell and to see how it lets the iodine in but doesn’t let the corn starch go anywhere. In the beginning, the class took about two spoons fills and put it the the permeable bag. Later, the class poured 500 ml in a beaker. Iodine was added which lower the concentration. The bag was put in the beaker. After 15 minutes the class did analyses on the bag. The color had changed.
There are many examples of diffusion. One example is a campfire. If there was a campfire the the smoke would spread a wide amount of area. Another example of diffusion is when somebody is baking cookies; the smell of the cookies fills the house. A third reason is when a person is smoking a cigarette the smell and puff of smoke hovers around the person. Last but not least is the way ink spreads in a cup of water. Let’s say there a cup of water and you drop ink in the cup. The ink spreads around and changes the color of the water in the cup.
