Egg Osmosis Lab Report

For this past week in my science class I have been working on Egg Osmosis with my class. In my lab I had to place an uncracked egg in vinegar to remove its shell and to leave the semi permeable membrane exposed. Then I placed the egg in light corn syrup(a hypertonic solution) then after place it in water ( a hypotonic solution). Then I observed the osmosis of the egg. The egg has been in each solution for twenty four hours and I had to measure its mass in between each solution it gets put into. Some of the procedures that went into this lab were lengthy but it all turns out to show an egg’s osmosis, for the first day we started this lab me and my group had to observe the egg as it was still normal with no change then we had to figure out the …show more content…

My hypothesis was proven in the second day when I took it out of the beaker it was really squishy and mellow unfortunately that's the only thing I thought that would happen. The mass of the egg between these days has gone up and down it has started at 63 and climbed up to 83 in day two this means it massively increased at the cost of the vinegar on day three it dropped to 56 grams and it turned out to be like a deflated beach ball. On the final day the mass of my egg was 96 and it felt like jello it was really dense and it's like it took a lot of water out of that beaker. With my data from my graph there was a pattern that it increased then it decreased and increased again from 63 to 83, 83 to 56, and 56 to 96 grams this means on the graph it made a zigzag pattern in the egg osmosis lab. The volume of the liquid inside each beaker after each day was a starting from 200 mL to 170 mL, 170 mL to 160 mL, and 160 mL to 137 mL. This answers my problem question because it shows my data going up to my final answer of 96 grams and a volume of 137 mL this means it has started off a number and has increased and then decreased to a lower number than that start number then increased to a higher number than that other increase. The independent variable is the solutions, the dependent variable is the mass, the controlled variable is temperature, egg classification, and the time. My hypothesis was proven in a way but not thoroughly made clear through each day which means I kind of got it correct I had it correct when the egg will shed or melt its shell that's really
