contrast
* independent variable:in an experiment there is only one variable and its set by the person carrying out the experiment . * dependent variable: measured in all set ups during the investigation. * controlled variables: are quantities that the scientist wants to keep constant. so , the part of the experiment that does not depend on the variable is the controlled variable.
The scientist was smart.!

He observed the same movement. When the experiment was repeated with rock dust the same movement was observed.

The variable that the scientist changes in an experiment is called the independent variable. This is the factor that the scientist manipulates or controls to observe its effects on the dependent variable, which is the factor being measured or observed.
This procedure is called an in vitro experiment, which refers to experiments conducted outside of a living organism, typically in a laboratory setting.
The rate of movement observed in the experiment was 5 meters per second.
The rate of traffic observed in this experiment was 100 vehicles per hour.
Experiment
The rate of evaporation observed in the experiment was 0.5 mL per hour.

bacteria
The variable that changes as a result of a scientist changing another variable is called the dependent variable. It is the variable being observed or measured in an experiment to see how it responds to the changes made to the independent variable.
