it is a fair test
A controlled experiment
the dependant variable
Independent variables are variables that can be changed in an experiment, while dependent variables are variables that change as a result of an experiment. In other words, independent variables are what you change, and dependent variables are the results of the experiment.
A variable.
the things you change
In an experiment, factors that you change are called independent variables.
Control Variable
A constant is a variable that does not change in an experiment. It is used as a point of reference or comparison to measure the effects of other variables.
A constant is a part of the experiment that remains unchanged throughout the testing process. It provides a baseline for comparison with the variables being tested to determine their impact on the outcome of the experiment.
Control Variable
if any factor in an experiment changes, you have a brand new experiment. -A factor in an experiment that can change is known as a variable.
The variable that does not change in an experiment is called the control variable. It is used as a benchmark for comparison to observe the effects of the other variables being tested.
