An example of a scientific investigation design that uses independent variable and dependent variable in its design is a research that seeks to find out the effect of two different fertilizers on the growth of a tuber crop (yam). The independent variable in this case is the type of fertilizer used while the dependent variable is the corresponding growth of the tuber crop. In a research set up, the independent variable is the variable that causes a change in the dependent variable and the dependent variable is the one that is been measured.

When grapes are soaked in water, the grapes then swell up because grape's cells have a high concentration of solutes in comparison to the water. In other words, grapes have low concentration of solvent (that is water molecules ) in comparison to the concentration of solvent in water. In this situation, there will happen a process known as osmosis in which water molecules moves from a region of concentration of water to a region of low concentration of water through a semipermeable membrane. (the cell membrane of the grape's cell is also semipermeable,which only allows solvent molecules to pass through it)
