My design is repeatable by another person because it clearly tells you what to do on the procedure and how long it would take, I also mentioned the amount of liquid poured in to the container so that if people repeat my design, they should get a result similar to ours. Therefore, my design is repeatable because it shows you what to do clearly, the specific amount of time, and the amount of liquid to pour in the container. I also defined the IV and the IDV along with constants to make sure that it doesn’t go wrong.
I realized that not coloring the parts with my IV and DV on my design might have been an issue in my data collection because as scientists, we need to organize our data so that it would be easier to follow and define parts of our investigation. I did not do that so my design might be hard to follow. Therefore being an issue to my design. Another improvement I would like to make is make sure my procedure and data table is clear so that it would be easier to know the change of the mass of the egg. Also, even if my procedure is really specific, it is not clear due to the limited space on the paper, therefore being a challenge.
An improvement that I would make if doing this investigation again is coloring my design so that it would be easier to follow since it would clearly explain how my IV and DV is related to my procedure and model of my investigation, therefore being easier to follow and will be a huge improvement to my design. It would also be good if I could make my graph and procedure more clear so it would be easier to follow my procedure which makes sure its easier to follow my investigation and easier to follow my data.
Additional information that I would like to collect to have me understand more about this phenomenon is a time laps of my investigation when the egg was put in a certain liquid for twenty four hours, it would be easier to understand the phenomenon because we don’t just observe what happens as a result, we will understand how it happened. Furthermore, a microscope would benefit this design even more, because the egg is a single cell and we can see the membrane but not the cracks in it, if we can use a microscope we will understand why water makes the egg increase in mass while corn syrup decreases the mass of the egg.
When I first watched the phenomenon, I thought that the egg was some how losing mass in corn syrup and it was increasing mass in water. My guess was that the egg was somehow like a balloon, the water inflates the balloon and the corn syrup deflates the balloon, my evidence supports that because before the experiment, one of the eggs weigh 64.59 grams, after we took off the shell and put it in water for 24 hours, the egg weighed 88.5 grams, showing an increase in mass of about 22 grams. Therefore, water does inflate the egg and increase its mass. However, when another egg was out in corn syrup after we removed the shell, the mass of that egg decreased. Before the experiment, the weight of the egg was 63.29 grams, after the experiment the mass of the egg changed into 41.1 grams.
The corn syrup also changed the mass of the egg by about 22 grams but negatively. Now I think that there are gaps in the cell membrane (security system of the cell, lets water and air in and removes waste from the cell) and the water can get through therefore increasing the mass that is inside the egg. However, the corn syrup particles are too big to get through the gaps, so it pushes itself against the egg and forcing particles inside the egg to come out of the egg, therefore decreasing the mass of the egg. Our observations show that the corn syrup becomes more runny and it becomes more transparent, showing that something has changed the liquid from corn syrup to a cross between corn syrup and another substance. This shows that something has came out of the egg and actually affected the corn syrup, therefore causing the egg to lose mass and change the corn syrup. Key evidence to support this is my observations after the experiment.
Materials moves in or out of the cell by passing through the cell membrane/cell wall and cell membrane. In plant cells, the cell wall is a nonliving layer surrounding the outside of the cell protecting it and supporting it. The cell wall is made up of a tough material called cellulose, even if its hard for some substances to get through, its easy for substances like air and water to get through. After the cell wall (animal cells don’t have cell walls), there is the cell membrane which is inside the cell wall or in some cases, protecting the cell from the outside. The cell membrane controls what gets through and out of the cell like a security guard where you show them your ID to get in and your ID to get out, the guard won’t let people without IDs in just like the cell membrane. The cell membrane lets particles such as water and air to get in and let its wastes out in order to live. The function of the membrane is to choose what goes into the cell and what goes out, the structure has little holes in it that blocks big particles such as corn syrup to go through and lets small particles such as water and air particles to go through, this is how structure and function is in this phenomenon. This is also the idea behind the increase of the mass since water particles are small and can go through the egg, therefore increasing the mass. This also shows why corn syrup doesn’t increase the mass of the egg since it can not go through the membrane, therefore not increasing the mass but decreasing it.The movement of matter is based upon the size of the particle, there are cracks in the cell membrane, the cracks are enough for small particles like water and air, but too small for big particles such as corn syrup. This controls the movement of particles in the cell. This could be related to the egg, the membrane of the egg (Because the egg is a cell) keeps corn syrup out and water in, therefore the egg changes mass upon its own will since it lets water in to increase its mass and of course keeping it alive. My evidence supports this because when it was in water, the egg’s mass increased by about 22 grams (64.59-88.5 grams) where it did not in corn syrup, this shows that the water got pass threw the cell and into the egg where it did not for corn syrup.
The cell (smallest functional unit of a living organism) consists of 3 main parts: cell membrane (security centre of cell), a cytoplasm (Contains the most things inside a cell such as organelles and cytosol), and a nucleus (the control centre of the cell; directs all of the cell’s activities).
