are the slower rate of movement.1 2.3. The aim of this investigation is to evaluate the process of Osmosis and Diffusion on different concentrations of sodium chloride on a de-shelled chicken egg over a period of 24 hours. 2.4. My hypothesis relating to this investigation is that the de-shelled eggs in different sodium chloride solutions will absorb the water through the process of osmosis which will cause the eggs to increase both their weight and size. 2.5. The outcome

There was seven different substances that were being tested; Mossy Zinc (Zn)‚ Magnesium (Mn)‚ Copper (Cu)‚ Magnesium Oxide (MgO)‚ Copper II Nitrate (Cu(NO3)2)‚ Copper II Carbonate (CuCO3) and Sodium Chloride (NaCl). There were four test tubes set up for the experiment. Each substance was divided amongst

The second model which I will be talking about is the stages of change model. This model has been broken down into 5 various stages and they are the pre-contemplation stage‚ contemplation stage‚ preparation‚ action and finally maintenance and in these 5 stages which is used to change something as part of our lives. The model has now been accepted and we see that it is used in substance use services like alcohol and other illegal substances. The first stage is called the pre-contemplation‚ this is
