What is the control and independent and dependent variable in the 'how many drops of H2O can fit on a penny'?
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.
What is a dependnent variable?
A dependent variable depends on the independent variable. If you are doing an experiment about how temperature affects the heat of water then the independent variable would be the temperature, as that is what you are going to change, and the dependent variable the water as the temperature of the water depends on the temperature surrounding it.
What is the independent and Dependent variable in will fish tank water and tap water differ when used for tomato plant growth?
the independent of the tomato plant is the leaf and the dependent variable is the root
What a testable question about the natural world that contains an independent variable and dependent variable?
That the surface tension of water varies with the water's temperature. In this case, temperature would be the independent variable and surface tension would be the independent variable.
Suppose you set a glass of water in direct sunlight for 2 hours and measure its temperature every 10 minutes What would be your dependent variable and what would be your independent variable?
Independent variable is time; dependent variable is temperature.
What best describes the relationship between a dependent variable and an independent variable in a scientific investigation?
The independent variable is what you are changing in the experiment to get varied results. The dependent variable is the result of what you have changed. So the dependent variable depends on the independent variable. For example, if you are experimenting with the effect of water on height of a plant, the different amounts of water that you give the plant is the independent variable. The height of the plant that you measure as the result of the water is the dependent variable.

What role does independent and dependent variable play in controlled experiments?
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.
Things that may change during a experiment are called?
'Variables' are any factors that can be controlled, changed or measured. There are two types: the independent variable and the dependent variable. The independent variable is the condition that you change and the dependent variable is what you are observing. So if you are trying to measure the effect of water on plant growth the water would be the independent variable and the plant growth would be the dependent variable.

the independent of the tomato plant is the leaf and the dependent variable is the root
What is a dependent or an independent variable?
An independent variable is something that you can change in your experiment. A dependent variable is something that changes depending on what your independent variable is. Example: You have two plants. You water one every day and you water the other one every other day to see how fast they'll grow. Your independent variable is water, because you can change how much you give to the plant. Your dependent variable are the plants, because they'll change depending on how much water you give them.
What a testable question about the natural world that contains an independent variable and dependent variable?
That the surface tension of water varies with the water's temperature. In this case, temperature would be the independent variable and surface tension would be the independent variable.
What are the independent variable and the dependent variable?
An independent variable is the variable you can change in an experiment. On a graph, it's on the X-axis. A dependent variable is the result of changing the independent variable. It is literally dependent on it. The dependent variable goes on the Y-axis.
Suppose you set a glass of water in direct sunlight for 2 hours and measure its temperature every 10 minutes What would be your dependent variable and what would be your independent variable?
Independent variable is time; dependent variable is temperature.
What is the dependent variable in an non-experiment project which describes the water cycle?
If you are not doing an experiment, there is no variable.
Describe the difference between a dependent and independent variable?
The dependent variable changes as a result of changes in the independent variable.Put another way,The Independent Variable is manipulated, and is known as the changed variable.The Dependent Variable is responding, and is known as the result.Example : In an experiment to test the effect of heating on evaporation, the various temperatures would be the independent variable, which will be changed by the experimenter. The amount of water that evaporates in a given time is the dependent variable, which is the data sought in the experiment.
