Potato Osmosis Paper

I. Introduction: The purpose of this experiment is to observe the osmosis reaction in a potato with salt and water. In cooking cooks will soak their cut potato's in water if they will not use them immediately. This allows the potato's to be used later without turning color. The experiment shows the flow of water through the membranes of the potato with salt over a period of four hours.
II. Objective: The reaction of the potato to the side submerged in water and the half excavated with salt.
III. Raw Materials: Potato, Salt, Water, clear container, knife.
IV. Procedure: 1. The potato was cut in the front, back, and sides. 2. The inside was excavated for a space to place the salt. 3. Potato was then placed in a clear container. 4. The container was then filled with water, filling up only up to half of the potato. 5. Four hours allowed to elapse.
V. Data Once the potato was cut into a cube shape, it was placed into a container with water. Salt was then added to the excavated part of the potato. The potato was firm and had its natural color in the beginning of the experiment. Within the first hour the water turned light orange/pink in color. The exposed part of the potato also began to change color from its natural beige to light brown. The top part of the potato began to slightly lose its firm shape.
In the second hour of the experiment, the water changed into a darker orange/pink color, the potato color grew darker as well. By the second hour the side walls of the exposed potato began to slightly cave into the middle.
By the third hour the water continued to change into a darker orange/pink color. The side walls curved inward, causing an hourglass shape. The potato also lost its firmness and became brown/black in color.
In the fourth and final hour the water was a dark orange/pink. The bottom part of the potato was cube shape and beige in color, while the top part turned black/brown in color. The exposed top half curved further
