In order for the results to be valid, the dependent variable can only be affected by the independent variable, so somethings need to be kept CONSTANT. The things that need to be kept constant are called CONTROLLED VARIABLES. Even if controlled variables are affecting the dependent variable(s), which they usually do, keeping them constant will ensure that all trials of an investigation were equally impacted by the controlled variables, therefore allowing one to see the impact of an independent variable on the dependent variable.
All in all, a 'constant' in a science experiment should actually be called a 'controlled variable' and the description of such a variable is described in the third point. Hope this clarifies.
so scientist can compare result
The constants in an experiment is any factor that remains the same and does not change. These things are kept the same throughout each trial of the experiment.
A constant in an experiment is the object or value that does not change through out the experiment.
things in an experiment that stay the same are called constants.
the constants are....how much ice creamwere placedtemp. in room
In a lab experiment, constants are the conditions that are kept the same throughout the experiment to ensure that the results are valid and reliable. Variables, on the other hand, are factors that can change; they are typically categorized into independent variables (which are manipulated) and dependent variables (which are measured). Managing constants and variables is crucial for establishing a clear cause-and-effect relationship in the experiment.
they are the things that don't change in an experiment/ that don't receive any special treatment.

Constants
In a soccer experiment, constants could include factors such as the size of the field, the type of ball used, the duration of the match, and the rules of the game. These are elements that do not change throughout the experiment and are kept consistent to ensure reliable results.
In an experiment, constants are variables that are kept consistent and unchanged throughout the testing process. These variables help ensure that any changes observed in the experiment are due to the manipulated variables and not external factors.
