Biology investigation Osmosis For this investigation we are going to find out whether potato chips placed in a range of different concentrated sugar solutions increase or decrease in mass. Background knowledge Osmosis is the passage of water molecules from a weaker, dilute, solution into a stronger, more concentrated, solution through a semi permeable membrane. Each cell in a leaf is surrounded by a membrane, which separates the contents of the cell from the outside. The …showed first 75 words of 1368 total…

…showed last 75 words of 1368 total…chip didn't gain as much weight. The results I have gathered support my prediction of which chips would gain or lose weight. The graph produced from my results also matches my predicted graph. Evaluation Overall the investigation went well, apart from the first set of results not turning out as expected. The final results proved my prediction and showed whether potato chips placed in a range of different concentrated solutions increase or decrease in mass.
