Material and Methods * Osmosis : -thistle funnel tube -dialysis tubing sack -saturated NaCl w/food coloring -beaker with distilled H2O The experiments begins with the construction of a simple osmometer by obtaining pre-soaked length of tubing ‚opened and tied at the end. The tube is filled with saturated NaCl solution (with added food coloring) and the thistle is inserted in the dialysis tubing. The dialysis tubing is sealed to the thistle funnel with dental floss and placed in a beaker

The Effects Sodium Chloride has on pond water Introduction Ponds are depressions in the ground that fill with water from either run offs or melting snow or rain fall from many different weather changes. There are two types of ponds permanent and temporary. Ponds tend to be much smaller in size and are usually only six to ten feet in depth. This differs from a lake because the size of a lake is much larger and is much deeper. The temperature of a pond is usually the same from top to bottom and

amount of ATP the seed can generate in order to grow‚ the temperature of the environment and the amount of sunlight the seed receives (Ghaderi-Far et al.‚ 2010). The purpose of this study was to observe the effect of different concentrations of sodium chloride have on the germination of lettuce seeds‚ Lactuca sativa. A study done by Katembe et al.‚ (1998) stated that an increase in salt solution in the environment of the seed will slow down water imbibition‚ therefore‚ preventing germination and root growth

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 varied
