Demonstrating Osmosis in Potato
The data we had did not support the definition of Osmosis, Osmosis is the diffusion of water through a partially permeable membrane from a region of lower solute concentration to a region of higher solute concentration; the data we collected did not seem to fit into this. The potato chips were suppose to lose more mass in the higher concentrated solution as the water from the potato chip will flow out to the higher concentrated solution as the water inside the potato has a lower solute concentration but this did not happen in our experiment. The results did not seem to match with the meaning of Osmosis, so we had to use the data given to us by Mrs. Walters. By using the new data and converting it into a graph we can see that the mass of the potato decreases when the concentration of the sucrose solution increases. By looking at Mrs. Walters result we can know that a hypertonic environment would have been created if the potatoes were left overnight on the test tubes because the water was flowing outside from the cell which resulted into its losing its mass.

I will begin by ranking the errors we had in this experiment. No repetition, Condition of the potatoes, Electronic balance, and Temperature.

No repetitions
I think this was our major flaw in this experiment of not repeating the experiment. Repetition would have given us a more accurate and reliable data to support our argument on Osmosis. We could not repeat our experiment because of lack of time. Repetition is essential for scientist because if Mrs. Walters was not there then we would have used the wrong data; it was her who pointed out that our data was incorrect. So an improvement to this is if we do a experiment next time we should at least repeat our experiment 3 times. Condition of the potatoes

Our experiment was not successful because of the potatoes we used in the experiment. The potatoes were frozen, so this could have an effect in...
