Science is a pursuit that has no end. As long as we breathe, we ask questions and try to find answers to those questions. To find answers to our questions, people conduct experiments. The results of each experiment help us to better understand how things work. How we conduct our experiments is very important. That's why we need to learn about experimental design.
Experiments are written with very precise steps so that the scientist can precisely repeat the experiment to verify the result. Also, before your result can be considered true and valid, your peers, other scientists, must verify your results by following your experimental procedure precisely.
Sometimes, due to poorly written or poorly followed procedures, experiments lead to unintended consequences. Those consequences could include loss of money, time, points toward your grade, resources, and injury to yourself or others.
Every procedure should have the following:
If other people follow your experimental procedure and get the same result, you may have discovered a previously unknown truth about the universe! If other people follow your experimental procedure and get a different result, it may mean that your experimental procedure is flawed and will need to be rewritten and retested.
