Only one at a time, since you would not know which variable(s) made the observed changes. You would need to measure each change separately. But if you want to test multiple variables, then you would need to test every possible permutation. If you want to test two chemicals, then you should test your control (a placebo using neither substance), substance A, substance B, and both substances.

What are the variables of fair test?
In a fair test, the key variables are the independent variable, which is intentionally changed or manipulated; the dependent variable, which is measured or observed; and the controlled variables, which are kept constant to ensure that any observed effects are due solely to the manipulation of the independent variable. Maintaining these variables consistently allows for accurate comparisons and valid conclusions about the relationship between the independent and dependent variables.
Do you change the variables in a fair test?
In a fair test, only one variable is changed at a time while keeping all other conditions constant to ensure that any observed effects can be attributed to that specific variable. This controlled approach allows for accurate comparisons and valid conclusions about the relationship between the variables. If multiple variables are changed simultaneously, it becomes difficult to determine which one is responsible for any differences in the results. Thus, maintaining the integrity of a fair test relies on careful manipulation of just one variable.
What is variable in conducting a scientific experiment?
In a scientific experiment, a variable is any factor or condition that can be changed or controlled to test its effects on the outcome. Variables are typically classified into three types: independent variables, which are manipulated by the researcher; dependent variables, which are measured and observed; and controlled variables, which remain constant to ensure a fair test. Properly managing these variables is crucial for obtaining reliable and valid results.
What is any condition in a experiment that can be changed?
A condition in an experiment that can be changed is known as a variable. Variables can be independent, dependent, or controlled. The independent variable is manipulated to observe its effect on the dependent variable, while controlled variables remain constant to ensure a fair test. This allows researchers to draw meaningful conclusions from the data collected.
Define a fair test?
A fair test has many differences from an unfair test. For example, a fair test is where if you have studied, there would be question-related to what you have gone through like if you are learning density, you would learn how to calculate it. But if the questions are unrelated to your research or what you have been tasked/ assigned, then that would be unfair and therefor wrong.
What type of experiment is it when one variable is changed while the other variables are controlled?
its called a fair test. :)

What is fair test?
A fair test is when you test something equally changing the variables but keeping everything else the same
How do the test variables and outcome variables in an experiment compare?
Test variables are the factors that are intentionally changed or manipulated by the researcher in an experiment, whereas outcome variables are the factors that are measured and affected by the test variables. Test variables are the independent variables that are controlled by the researcher, while outcome variables are the dependent variables that change in response to the test variables. The relationship between the test variables and outcome variables is explored to determine the effect of the test variables on the outcome variables.
How many variables will change in a fair test?
In a fair test, only one variable should change while all other variables are kept constant. This helps to isolate the effect of the variable being tested and ensure that any observed changes are a result of that specific variable.
How many independent variables should an investigation have?
There can only be one independent and one dependent variable. All other variables should be classed as control variables and must be kept constant to achieve a fair test.
What is any condition in a experiment that can be changed?
A condition in an experiment that can be changed is known as a variable. Variables can be independent, dependent, or controlled. The independent variable is manipulated to observe its effect on the dependent variable, while controlled variables remain constant to ensure a fair test.

What is fair testing in science?
Fair testing is when you test something with many variables, but you must change one variable. e.g. testing the different types ofdrinking water. [Tap water, hose water, etc.
What is the word for the one variable that is purposely changed to test a hypothesis?
The independent variable is the one that is changed by the scientist.Control variables are kept unchanged in an experiment.Dependant variables are those that change as a result of the independent variable being changed.
What are the examples of fair test?
Examples of a fair test include control experiments where only one variable is changed at a time or repeat trials to ensure consistent results.
