Prediction I predict that the higher the concentration of salt, the lower the mass the potato cylinder will become. This is because there is a greater concentration of water molecules inside the potato cylinder, so the water will drain from the cylinder by osmosis, to where there was a lower concentration of water molecules, so therefore the mass of the cylinder would decrease. If there was a low concentration of salt in the solution, the cylinder would increase in mass. This is because there is a higher concentration of water molecules in the potato cylinder than in the solution....
not a big change in the mass of the potato. The graph showed me that my line of best fit was almost like straight diagonal line with a positive gradient. I did have one odd result which I could have improved if I had repeated the test. My table showed that the higher the concentration of salt, the lower the mass of the cylinder will be. This is because if there is a high concentration of salt the water in the cylinder will diffuse through the semi-permeable wall of the potato cell where there are less molecules of water.

Investigation For this experiment we plan to investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato core of a given size. Osmosis is defined as the net movement of water or any other...

Hypothesis: The higher level of concentration of the sugar solution, the greater reduction of the potato cylinder will be. Prediction: I think that the higher the concentration of the sugar solution, the bigger the length difference will be. This will be because the water molecules will flow out of...

Aim The aim of the investigation is to see the effect light intensity has on the rate of photosynthesis. Background Information The rate of photosynthesis is affected by a number of factors including light intensity, temperature, water, carbon dioxide and availability of nutrients. If the conditions the...
