 ScienceExample of Independent and Dependent Variables If a scientist conducts an experiment to test the theory that a vitamin could extend a person’s life-expectancy, then:The independent variable is the amount of vitamin that is given to the subjects within the experiment. This is controlled by the experimenting scientist. The dependent variable, or the variable being affected by the independent variable, is life span DensitySink or FloatWhile their mass may be the same (1kg), the volume of lead is a lot smaller than that of feathers. As there is the same mass stuffed in a smaller space, it must be denser. The density of water is 1 g/cm3, so if the density of the lead is more than 1g/cm3, it has to sink. On the contrary, the feathers' density is probably less than 1g/cm3, which makes them float.In other words, whether an object will float or sink in a certain liquid (or gas) depends on their density with relation to the density of the liquid
