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...

My Views on the Process of Evolution For many years people have asked the questions, "How did we get here?", and "How did mankind come to exist?" Astronomers, philosophers, and even mathematicians have come up with explanations. I believe in the theory of Theistic evolution. It is the belief...

An investigation into how the amount of oxygen is produced by changing one variable effects the decomposition of Hydrogen Peroxide in the presence of the enzyme. Hydrogen peroxide Water + Oxygen 2 H2O2 2H2O + O2 This shows us that when the H2O2 has reacted with the...

Introduction Osmosis is defined as the diffusion of water molecules, down a water potential gradient, across a partially permeable membrane. If the solutions on each side of the partially permeable membrane are equally concentrated then there will be no net movement of water across the membrane. If the solution...
