The controlled variable is the penny. The independent variable is the water. The dependent variable is the amount of water able to fit on the penny.
amount of light amount of water amount of force amount of heat etc.the variable that changes and the one that the dependent variable depends on to change
the Independent variable is the variable that is not effected in any way by the dependent variable, where as the dependent variable is. for example, amount of water that has flown through a tap in a set number of seconds. the number of seconds is not effected in any way by the amount of water, as water flow has no effect on the passing of time. however, if water is coming out of the tap at 1liter per second, then the amount of time that has passed has a significant impact on the amount of water (after one second, 1 liter will be present, after 2 seconds 2liters etc.).
An independent variable. This is because you can manipulate the variable so it is said to be independent of the other variables. This is different from the dependent variable which is the variable you are measuring the change in. For example in an experiment to see how the amount of water given to a plant affects it's height, the amount of water is the independent variable, because it is the variable you can change, while the height of the plant is the dependent variable because we want to see how the change in the amount of water affects it.
something like time. Like say you want to work out how much water will be in a trough that has water coming in at 2 L per minute - the amount of water in the trough is dependent on the time at which you are trying to calculate the volume of water. so in this case time is an independent variable and the amount of water is the dependent variable... hope that helps. :) example of a variable

I dont know about the control but the independent variable is the amount of salt water and the dependent variable is the amount of water and salt rendered.
The independent variable in an controlled experiment is what you are changing (for example, amount of water or sunlight a plant gets). The dependent variable changes because of the independent variable. Its the outcome of the independent variable.

The quantity of salt added to water is under your control and it will change the boiling point of water,i,e. the temperature of water. So quantity of salt is an independent variable while the temperature of water is dependent variable, when other factors are kept constant.
independent variable is the water i dont know

The independent variables are the milk and water, while the dependent variables are the plants, because they don't change.
The independent variable is the number of tickets purchased and the dependent variable is the amount of money spent.
Observing the change in salinity of water over time can be independent or dependent. This depends on the experiment.
