scientists often test their hypotheses with controlled experiments. which of these is a rule for conducting a controlled experiment?
a. change at least two variables at a time
b. keep all variables constant
c. change as many variables as possible
d. change only one variable at a time
Answers
Changing only one variable at a time is a rule for conducting a controlled
experiment.
Controlled experiment involves the use of dependent and independent
variables . Changes in the independent variable brings about a
corresponding change in the dependent variable which is then recorded.
It is however important to note that changing more than only one variable at
a time won't accurately determine if the changes in the results were as a
result of one cause. This is why only one variable has to be changed at a
time.
