Question

In Science experiments, it is very important to "control the variables" so that there is only ONE independent variable and ONE dependent variable. We "control the variables" by making anything else that could change during the experiment into a constant. For example, if you are doing an experiment to find out what material can hold more water, then it is important to make sure all the materials you are testing are the same size. Why is it so important to control the variables? What would happen if we did not control them?

Answer 1

Answer:

See the answer below

Explanation:

It is important to control the variables so as to isolate the dependent and the independent variables from other variables. Since the value of the dependent variable varies with the independent variable, not isolating the variables would lead to interference of multiple variables, and hence, knowing which variable produces a particular effect will be difficult. In other words, the primary aim of experiments would not be achievable without isolating the dependent and the independent variables.
