What else can I help you with?
What reason is the primary rationale for controlling variables in an experiment?
To eliminate alternative explanations for the result of an experiment
A controlled experiment allows the scientist to isolate and test what?
to isolate and test single variables
What does the word dependent variable mean in science?
In an experiment the variables whose values are measured. A scientist measures how these variables respond to changes they make in an independent variable.
What type of variables are in experiment?
the only variables in an experiment are the independent variables [the thing in an experiment your going to change. and the dependent variables [the thing in an experiment your going to measure.
What controlled variables in science?
The number of dependent variables in an experiment varies, but there is often more than one. experiments also have controlled variables are quantities that a scientist wants to remain constant, and he must be observe them as carefully as the dependent variables.
How can you eliminate confounding variables in your experiment?
To eliminate confounding variables, or variables that were not controlled and damaged the validity of the experiment by affecting the dependent and independent variable, the experimenter should plan ahead. They should run many checks before actually running an experiment.
How many variables does a scientist change in an experiment?

In which step of the scientific method would a scientist determine the specific variables of the experiment?
Observation.
What are variables that the scientist changes in an experiment?
Scientists change the independent variable but measure the dependent variable; other variables are kept constant.
A controlled experiment allows the scientist to isolate and test what?
to isolate and test single variables
What is it called when a scientist is conducting an experiment and and it has factors that can affect the results?
If they are supposed to affect the results in the experiment ie. they are what is being tested, they are the test variables. If they must be kept the same to ensure a fair test ie. the scientist is not testing with them, they are called control variables.
When controlled experiment is not possible why do scientist try to identify as many relevant variables as possible?
to gather data from data to create an controlled experiment
What does the word dependent variable mean in science?
In an experiment the variables whose values are measured. A scientist measures how these variables respond to changes they make in an independent variable.
The variables that do not change in an experiment are what?
Variables that do not change in an experiment are independent variables.
What are variables that do not change in an experiment?
Variables that do not change in an experiment are independent variables.
What is manipulated variables in experiment about boiling point of water?
Manipulated variables are variables that a scientist deliberately adds in to tweak the outcome of his or her experiment. For instance, a scientist may choose to add certain compounds into a pot of water to see if it may affect the boiling point.
