- I see that the egg sunk to the bottom of the solution, after 3 days the egg cracked and became squishy. What this means is the the egg had a low concentration of vinegar inside, and a high concentration of vinegar outside the egg, this would make the vinegar ahyper tonic solution, hypertonic solution means that there are more solutes in the solution , after a few days the vinegar flowed inside through the eggs semi permeable outer layer, this would mean the water is flowing into the egg. The eggs mass went from being 65.8g to being 104.15g. The vinegar was a less viscous and a more liquid substance with a yellowish tinge.

- I see that the egg is now floating in the solution and has cracked more. The egg is floating because of the difference in density from vinegar to corn syrup. After 1 day the mass decreased from 104.15g to 71.4g, this shows that the vinegar went through the semi permeable outer layer of the egg, which shows that there was a high concentration of vinegar inside and a low concentration outside making it a hypo-tonic solution, a hypotonic solution means that there are less solutes in the solution. This would mean the water is flowing out of the egg. The corn syrup was more viscous and looked more like syrup, the corn syrup had a very clear appearance.

- I see that the egg sunk in the water and after 1 day the egg grew in size. This means that water flowed through the eggs semi permeable membrane, meaning the water flowed into the egg. This would make the water a hypertonic solution because the water went to the low concentration in the egg. This shows that the concentration gradient is Low on the inside and high on the outside of the egg. The size of the egg increased along with the mass, the mass increased from 71.4g to 105.86g. The water was very liquid, not viscous, had a clear appearance like the corn syrup but for distinguishing purposes the water is blue in this storyboard.
