Once you've developed a hypothesis, you must design and conduct an experiment that will test it. You should develop a procedure that states very clearly how you plan to conduct your experiment. It is important that you include and identify a controlled variable or dependent variable in your procedure. Controls allow us to test a single variable in an experiment because they are unchanged. We can then make observations and comparisons between our controls and our independent variables (things that change in the experiment) to develop an accurate conclusion.

We can define science as a methodical approach to the acquisition of knowledge . This important word distinguishes how a scientist works from how other people learn about the world. Science is an approach that is methodical, and that approach helps acquire knowledge. Science is not the knowledge gained through the approach. Knowledge can be gained through a variety of ways, but science acquires knowledge methodically.
