How many variables do you need in a science experiment?
Ideally, an experiment should test only one variable (the independent variable) at a time. If you have two or more variables changing at the same time you have no way of knowing which variable is causing your results.
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.
What are the 3 scientific variables?
The three scientific variables are independent variables, dependent variables, and controlled variables. The independent variable is the variable that is manipulated or changed by the researcher. The dependent variable is the variable that is measured or observed in response to the changes in the independent variable. Controlled variables are the factors that are kept constant to ensure that they do not influence the relationship between the independent and dependent variables.
What kind of variable is part of the experiment that is affected by the independent variable?
Dependent Variable the independent variable is the one you change to get the dependent variable. The control group is the thing that you leave the same throughout your experiment. Hint: You don't want too many independent variables, it will mess up the experiment.
Can there be more than one independent variables in a experiment?
In general yes. But it really depends on the experiment. If you want to know if it hurts to punch a wall, you don't need an independent variable (unless you want to compare the magnitudes of the pain). But for school experiments, most of the time, if not all of the time. Yes.
How do you pick out independent variables and dependent variables?
An Independent variable is what you control; you decide the focus of your experiment and what you control on the independent variable. Dependent variable is what you want to look at or find results for; you decide what you want to see from manipulating your independent variable.
How many variables are supposed to be in a science experiment?
Most science experiments will have two independent variables. Fundamentally, an experiment will want as few variables as possible for better results.
What are Confounding Variables?
In any experiment there are many kinds of variables that will effect the experiment. The independent variable is the manipulation for the experiment and the dependent variable is the measure you take from that experiment. Confounding variables are things in which have an effect on the dependent variable, but were taken into account in the experimental design. For example, you want to know if Drug X has an effect on causing sleep. The experimenter must take care to design the experiment so that he can be very sure that the subjects in the study fell asleep because of the influence of his Drug X, and that the sleepiness was not caused by other factors. Those other factors would be confounding variables.

How many variables does a controlled experiment test?
As many as you need. You can't change more than one if you want accurate results.

What have you learned about variables?
1) I learned that you can have as many variables as you want. 2) You can change the variables. 3) Variables is used in an experiment. 4) A variable is something that can be changed, such as a characteristic or value. Variables are generally used in Psychology experiments to determine if changes to one thing result in changes to another.
What is true about a controlled experiment?
Scientists perform controlled experiments in order to reduce as many third variables as possible. This means they are trying to prevent variables not directly related to the study from influencing the results.
How do you come up with a hypothesis for a lab?
The lab would be used to test your hypothesis to whether or not you were correct. You would first want to form a hypothesis and then gather data to support or discredit your hypothesis. The hypothesis could be testing anything essentially.
