Explanation:
Independent variable.
It is the factor that the scientist can change to obtain
Different results
Example:
In Galileo's experiment on the free fall of bodies,
Galileo was throwing a stone from a certain height and half the
time it took to drop an object.
In this case the dependent variable is the height from where
launched, since Galileo decided from what height he could throw the
object.
- Dependent variables.
This variable depends on the independent variable and its values
will vary according to how the scientist changes the variables
independent.
Returning to the example of Galileo's experiment, the variable
Time is dependent, since Galileo could not decide how long the object was going to take. The time it took for the object to take
reaching the ground depended on the height at which he threw himself.
The objective of the experiment in general is to observe how the
dependent variable is provided as we change the variable
Independent.
- Control variables
The control variables are the ones that remain constant every
Once we performed the experiment. These variables we cannot
control, and will not change when we move the
independent variables.
In the case of Galileo's experiments, some variables of
control can be the temperature of the day when the
experiment or wind speed. Galileo could not control the
temperature or wind speed. And when he threw his
objects these variables did not change.
They are called variables because they change per day and almost never
They are equal.
These are sometimes variable if they affect the measurements made.
That's why it's important to report them when the experiment is done.
