(A) Dependent variable: Temperature of the water
(B) Independent variable: Depth of the pond
Independent and dependent variables:
The experiment we are analyzing is measuring the temperature of a pond at different depths.
it is obvious that as we go down the pond the temperature of the pond must decrease as it is less exposed to the sunlight or say open surroundings.
An independent variable is a variable that is not dependent on any other factor or variable. It can be manipulated by the experimenter to observe its effect on other variables.
A dependent variable is a variable that is dependent on other factors or variables. It changes according to the change in the variable on which it depends.
In the given experiment, the depth of the pond does not depend on any other factors, an experimenter can take a measure of temperature at different depths of the pond, and the temperature varies as there is a change in the depth of the pond.
So, the depth of the pond is an independent variable.
And the temperature of the water is a dependent variable.
