Variables that are intentionally manipulated or changed in an experiment are called independent variables. These changes are made to observe their effects on another variable called the dependent variable. By controlling and changing the independent variable, researchers can determine its impact on the dependent variable and draw conclusions about cause and effect relationships.
I assume the term for something that is not changed during an experiment is called, the control. Any changes observed in the experiment, can be compare to the control, which is still be in the original form before the experiment began.
Four things that indicate a chemical change probably happened include color change, formation of a precipitate, evolution of gas, and change in temperature. These signs suggest that a new substance with different chemical properties has been formed.
They smell like rubber when you first get them but they can change their smells if things like hairspray and perfume touch them
An experiment should consist of an independent variable, which is the variable that is manipulated or changed by the researcher, and a dependent variable, which is the variable that is measured or observed to determine the effect of the independent variable.
yes **Why? I need more than just yes. Tell why.** ok ok ok its not always a sign that there is a reaction but in most cases it will be. things that show a reaction are temperature change (usually increase but not always) mass change, state change or physical change. hope this helps
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.
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.

You only change 1 iv ( independent variable in a experiment ) HOPE IT HELPS :)
A variable.
they are the things that don't change in an experiment/ that don't receive any special treatment.
It could be one of at least two things. If it is a thing that you intentionally kept from changing, it is a control variable. If it is a variable that you left free to change, then you may have confirmed what is called the null hypothesis. The effect you hypothesized did not occur.
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.
variables
Facts in science change because scientists do experiment's and find out new things.
the things you change
Things that are kept from changing during an experiment are invariant.
