Prediction Osmosis is defined as ?â??the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low water concentration In a high concentration of water the amount of solute e.g. sugar is low. This could be called a weak or dilute solution. In a low concentration of water the amount of solute e.g. sucrose is high. This could be called a strong or concentrated solution. When two such solutions are divided by a semi-permeable membrane the water will move from the area of high concentration to the...
could be prevented by amalgamating sets of results, for example of a whole class, where each experimenter used a different potato. I think that three sets of results was a good number. However, I think that in order to improve my results, the last concentration 1 moler needs to be retaken as it is an anomalous result. Further work could be carried out to include concentrations that increased in 0.1 M rather than 0.2M. This would increase the accuracy and improve the graph. Other investigations could include using different varieties of potato or different plant tissues e.g. carrot.

Prediction and scientific theory: I predict that my results will show that as the concentration of Copper Sulphate CuSO4 increases so will the current passed through the circuit. Here is a small sketch on what I think may happen. I made the above prediction using the...

Several methods may be used to prevent aeolian erosion, to increase the height and stability of existing dunes, to repair damaged dunes and to encourage sand accumulation. Where fresh sand deposits around obstructions such as grass clumps show conditions conducive to natural dune formation, plantings of native vegetation or...

Prediction I predict that the more catalase used will speed up the reaction rate between the catalase and hydrogen peroxide. On a graph, as the concentration of catalase is increased the rate of reaction will increase forming a series of positively correlated lines, increasing in gradient as the catalase...

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...

Man has major effects on the planet earth. These include litter, noise, traffic pollution and deforestation. All of these are increasing problems and if solutions are not found soon these problems will reach the point of no return. Pollution is one of the main causes that I agree with...
