You don't want a lot of the factors && different things in an experiment to be changed because if they are all changed every now and then, it will completely change the experiment.
what is the factor that can change an experiment
It depends what kind of experiment you do. For some you just need one. For others you may change two variables. In most cases you only change one
A constant is an ingredient or part of the experiment that does not change. A control is also a required ingredient, however it can change. (this change could be MANY things depending on the experiment type.
A variable.
they are the things that don't change in an experiment/ that don't receive any special treatment.
variables
A variable represents things that are involved in an experiment. The control is the variable that doesn't change regardless of the experiment.
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.
An experiment is almost always designed so that two (and no more) things will change.-- You, the experimenter, will change one of them as you desire.-- That will cause a change in the other one, which you will carefully measure.
Facts in science change because scientists do experiment's and find out new things.
the things you change
in a science experiment many things are measured. it depends on what experiment one is conducting.
