Conclusion
Our next egg we submerged into Gatorade and it led to the egg gaining 14.4 grams to its original weight, which was 76.9 grams. In the end the egg weighed 91.3 grams. Not only that but the egg also turned red. Therefor the Gatorade was a hypotonic solution causing diffusion and osmosis to take place. We predicted that the egg would expand because the Gatorade was a hypotonic solution, and had a low concentration so the solute (Gatorade) would pass into the cell. Our prediction was supported by our data because the egg did expand in size due to the the Gatorade being so low in concentration.
The last egg that we tested in Rubbing Alcohol weighed 65.3 grams before we placed it in the solution. The next day we noticed that the egg was white and weighed 55 grams, and lost 10.3 grams. When we put the egg in Rubbing Alcohol it led to the egg shrinking only a little bit because the rubbing alcohol had almost the same amount of concentration as the cell. Due to diffusion the amount of solutes almost completely evened out. We predicted that if we put our egg in Rubbing Alcohol then it would stay the weight because the egg has the same amount of concentration as the rubbing alcohol. Our results were supported with our data. Not only did the eggs weight stay the same but when we opened it the edges were cooked! It was so interesting! We definitely want to push forward and learn more about how that happened so we are going to do an experiment by soaking an egg in the rubbing alcohol for more than 1 day, maybe 3, and see how long it takes for the egg to fully cook!
When we water plants the roots and the soil take in the water. The soil uses the water as air pockets for the plant to breathe and also receive more water when needed. When the roots take in the water, but they only take in a certain amount so that osmotic pressure does not take action, because that could kill the plant. The cell wall is important in this situation because it allows water to leak through if there is too much inside the plant. Its almost like sweating!
