Cellular Osmosis

Experiment: Cellular Osmosis
Control: Egg in water
Variables: Egg in Salt water, Egg in sugar water, Egg in vinegar

Day: 1
The water egg is normal, and is sitting at the bottom of the jar which is covered in bubbles.
The vinegar egg is at the bottom and has bubbles all over the egg, some of the bubbles are floating to the surface.
The salt water egg is floating at the very top of the jar with a small pile of salt at the bottom, it also has small air bubbles.
The sugar water egg is floating, you can see very little sugar at the bottom, and it has little sugar studs floating to the very top.

Day: 2
The Water control egg, is cracked and the jar is completely filled with bubbles.
The vinegar egg is floating at the top now and looks as if it is turning yellow, still covered in bubbles.
The salt water egg stayed the same, floating at the top.
The sugar water egg, sunk and looks soft.

Day: 3
The water control egg is the same, except for the crack got bigger
The vinegar egg is looks yellow. but is still the same
The salt water egg is the same except it lost all of the salt at the bottom.

Day: 4
The water control is the same with a ton of bubbles.
The vinegar egg sunk and is yellow with less bubbles on it and seems very very soft.
The salt is the only egg floating now.
the sugar sunk and looks very hard.

Dissecting  Day:
Egg from the fridge: It became our new control because the egg in water had a hidden crack. It was normal, the shell was soft to the touch, the yolk was a dark yellow, when the yolk is poked, the color of it is still the same dark yellow.

Water control egg: is no longer our control, the bubble was a membrane, when we cracked the egg, it was full of water, the crack in the egg had filled it with water, the yolk color before and after it was popped is the same dark yellow.

Salt water egg: feels normal. it was the only egg floating at this time, when you put it up to the sun, you can see the yolk, as well as you can see the salt inside of the egg,when we cracked it the yolk was thick, you could even pick it up a little.

Sugar water egg: is soft to the touch, and if you put it up to the sun, you can see the yolk in a short of blob shape, you can also see the particles from the sugar. when we cracked it, the yolk seemed soft, but turns out it was even thicker than the salt water.

Vinegar egg: It has no shell, the shell disintegrated and left us with the membrane which seems pretty solid, it is very squishy, and can be bounced. When we popped it, we realized it wasn't as solid as we though it to be. The yolk had shrunk into a small solid yolk ball.

Watch my short video bouncing the egg soaked in vinegar. It was my favorite part of the whole experiment.
