The independent variables are the milk and water, while the dependent variables are the plants, because they don't change.

What are dependent and independent variables in an observational study?
The independent variable is the factor in an investigation that the scientist is changing. The dependent variable is the factor which is measured. All other variables, factors which could affect the experiment, are controlled, or kept the same. For example, in an experiment to find out how light intensity affects bean plant growth, the independent variable would be the intensity of the light. The dependent variable would be the amount the plants grew. The controlled variables would be things like the temperature, the acidity of the soil, the amount of water given, the amount of CO2 in the air; in short, anything that could affect the results.
The effect of Gatorade VS water on seventh graders pulse rates while exercising what are the dependent and independent variables of this exeperiment?
Independent . . . what substance the 7th grader drinks Depoendent . . . his pulse rate
What are the independent and dependent variables in a small size bottle of water cost 1.99 and a large size bottle of water cost 3.49?
Either- and most people are ignorant of this fact. If your study is about how the size of the bottle affects the price, then the independent variable is the size of the bottle and the dependent is the price. However, if your study is to determine how the price that you pay affects the size of the bottle, the independent variable is the amount of money and the dependent is the bottle size.
What are the dependent and independent variable in what is the water cycle?
independent variable is the water i dont know
How are dependent and independent variables used in an experiment?
An independent variable is the variable that was changed. The dependant is what was measured. Eg. If you filled 3 cups of water - one with 1/4 of a cup, one with half a cup and one with 3/4 of a cup. Then you grab a spoon to find the highest note, then the amount of water is the independent variable and the sound is the dependant.
What do dependent and independent variables represent in science?
In science, independent variables are variables that you control the change of, to see how somethings changes as a result of changing these variables. Dependent variables are variables that change because the independent variables are changed, but you don't change directly. A good example of this would be an experiment where you're measing how cold a glass of water gets after putting in different amounts of ice in it and wating 5 minutes. The independant variable would be the amount of ice you put into each glass, because that's what you're directly changing. The dependent variable is how cold each glass gets, because that's the result you're trying to see by changing the independent variable - it changes because something else changes. Additionally, when graphing, independent variables are put on the x-axis (horizontal line), and dependent variables are put on the y-axis (vertical line).
What are the controls and variables for Seperating salt from water?
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.
What are the independent and dependent variables of adding salt water to boiling water?
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.
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.
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.

What is the independent variable on graphs?
it is the variable that you change during an experiment and is placed on the x axis. for example, if you are checking for the effect of light intensity on water uptake by a plant, the independent variable is the different light intensity values that you have and the dependent variable is the rate of water uptake which will be on the y axis.
Is water a variable?
It can be, it depends on your experiment. Independent variables are the variables in an experiment that will not change. If you want to do an experiment that tests how something reacts with water, then starting with a clean controlled water sample for each test would be necessary and an independent variable. Conversely, if you were testing the cleanliness of multiple water sources, then the ideology of clean water would be your dependent variable, which would change upon each testing. WIth your given information I cannot say whether or not you would want water to be either a dependent or an independent variable for your experiment.

Why is a control especially important in biological investigations?
There are three types of variables in a scientific experiment: Independent: Changes which you, the experimenter, control. Dependent: Changes which occur based on the changes you make (Independent) Control: Anything else which might change or influence the dependent variables outside of the independent changes made by the experimenter. Control variables must be monitored and controlled during an experiment to make sure that they are kept equal, otherwise they could make your results false or unreliable. In the Cool Science Projects link, they discuss a plant growing project. You wish to determine the growth difference between plants which have a full eight hours of sunlight versus plants which receive four hours of sunlight. The amount of time the plant is in the full sunlight is the independent variable and one of the dependent variables is the growth rate of each plant. There may be other dependent variables, such as the overall height of each plant. A good example of a control variable might be the amount or type of water used to hydrate the plants during the experiment. If you were to give one plant more water than another, or different qualities of water, you would be further influencing the experiment beyond the initial independent variable. You could not then say that it was strictly the duration of time in the sun which caused the growth or height differential, as it may have been other variables which caused these changes. It's important to be aware of exactly what changed within an experiment, and what did not, in order to keep your findings valid.
