In my hypothesis...
Yes, my hypothesis was correct. The one that we put in colored water did turn pink, it turned bigger, heavier, and softer. On the other hand, the one in corn syrup shrunk a lot and turned to a brown-like color. I knew we didn’t make a mistake about it because we followed our procedure and did everything correctly.
Discussion of my procedures, variables, and controls
As what I have written down in my procedure section already, our group has followed the procedures properly and did whatever was needed. The colored water and the corn syrup were independent variables because they didn’t depend on anything and they never changed because of other variables. The diffusion of water, as also known as the process of osmosis, was a dependent variable because it changed through out the lab and it changed depending on the situation. Such as if it was in corn syrup then it would shrink, and if it was in coloured water then it would expand. The size of the beaker, temperature, and the place were controlled variables. They never changed through the whole lab and they stayed the same.
In our lab our variables were considered, identified, and controlled because we used every item carefully, we knew which one was which and did everything properly. Good job!

Discussion of my results
Many things have changed since the before state. The eggs looked a lot different after being submerged in different variables. All eggs used to be healthy and normal; however, after egg 1 was submerged in to the colored water it turned bright pink, got heavier and bigger. Egg 2 was submerged in to corn syrup; the resulting aftermath was amazing. The egg shrunk to half of its size and turned brown in colour.
The insides of the eggs also looked very different then before. For Egg 1, it had normal yellow yolk, but the other parts of the egg were starting to turn pink. Egg 2 had brownish-yellow yolk. Also, there was less liquid inside the egg.
The egg that was put in to corn syrup had lighter mass after it was taken out; this is because corn syrup have lower concentration of water particles, and therefore it attracted the substance of the egg, making some of the particles go out. Egg 2, on the other hand, was put in to colored water. Therefore, the higher concentration of water particles outside of the egg, causing some of the particles to go in and making the egg heavier. This process is called osmosis.
The water left in the beaker also experienced much changes. There was less liquid left in the colored water than before, and that is because some of the particles went in to the egg. There was more liquid left in the corn syrup beaker, and that was because water from the egg came out.

Reflection on experimentation
The experiment was very successful, I learned a lot more about osmosis. I think everything went really nice and there is no need for any change. If I repeated the project then I would test a potato, because it is a simple and easy to understand tester.
This is a link that I think really explains osmosis (and diffusion)
