This paper demonstrates how the scientific method applies to ordinary, everyday situations rather than formal laboratory settings. Using two practical scenarios — a house losing electrical power and a laptop computer failing to turn on — the paper walks through each of the six core steps of the scientific method: asking a question, conducting background research, forming a hypothesis, testing the hypothesis through an experiment, analyzing data and drawing a conclusion, and communicating results. Drawing on Merriam-Webster's definition and supporting scholars, the paper shows how structured scientific thinking can guide anyone through systematic problem-solving in daily life.
Imagine coming home after a long day at work, flipping on the light switch, and nothing happens — the light does not come on. What do you do next? This everyday situation is actually an opportunity to apply the scientific method, a structured approach to problem-solving used across all scientific disciplines.
Merriam-Webster's dictionary defines the scientific method as all of the "principles and procedures for the systematic pursuit of knowledge involving the recognition and formulation of a problem, the collection of data through observation and experiment, and the formulation and testing of hypotheses" (Merriam-Webster 2011).
Asking questions is an extremely important part of the scientific method and of scientific experimenting. It is perhaps the most important part of scientific research, because everything else that is done is based on the question asked at the beginning of an investigation. All other components of a project exist to answer the initial question posed. Scientists have stated that "almost all scientific inquiry begins with an observation that piques curiosity or raises a question" (Harris 2012). Without a question, there is nothing for the scientist to investigate and therefore no experiment to conduct. Before a scientist can begin their work, they must formulate a question. The question is also known as the purpose of the experiment, because it asks the investigator to identify the goal of their scientific inquiry.
Why are the lights not turning on in this house?
It is important to be as informed as possible on any subject before beginning a scientific experiment. For example, if a person did not know about the dangers of mixing acids and bases before conducting a chemistry experiment, they could seriously harm themselves or others.
In this scenario, the individual checks other light switches in the house and determines that those lights are also not coming on. From there, the person checks whether any other devices in the house are receiving power — for example, appliances that normally display a light source, such as the clock on the microwave. After completing these checks, the person has determined that power is not reaching any visible sources in the house.
A hypothesis is an educated guess as to what explains something or answers a given question. It is called an educated guess because it is almost always based on knowledge a person has already gained about a given topic. For a guess to qualify as a hypothesis, it must be testable — that is, it must be something that can be examined through scientific inquiry. Additionally, the guess must be capable of being proven untrue. A hypothesis can either be confirmed or falsified; if there is no possibility of proving it wrong, it is not a true hypothesis. As Dr. Anne Marie Helmenstine (2012) explains, "It's easiest to test the null or no-difference hypothesis because you can prove it to be wrong. It's practically impossible to prove a hypothesis is correct."
Hypothesis: The power has gone out because of the weather.
An experiment is the means by which a hypothesis is tested to determine whether it is true or false. Experiments must be designed to test only the question on which the hypothesis is based; otherwise, the experiment is not appropriate for the inquiry (Popper 2003). They must also be designed to minimize errors so that the data collected from the test is accurate. Researchers should also remain aware of potential biases in the tests, as these could influence the results.
To test this hypothesis, the person could visit their neighbors and determine whether their power is also out.
"Interpreting experiment results and revising hypothesis"
"Applying all six steps to a dead laptop"
Use some means of reporting the information that has been learned through the scientific experiment. In Scenario 1, if the lights are not on in neighboring houses, then no further action by the individual is necessary. If the problem is isolated to the person's house, they should call the power company to report the outage and investigate further.
