The scientific method is a series of steps used to identify and execute hypothesies in an attempt to clarify scientific processes.
The scientific method will be applied to the following scenario: ? You arrive home late at night. You walk up to the front door, unlock it, and reach in to turn on the light switch located just inside the front door. The light does not come on! Now what? Accoring to the scientific method the first step in this situation would be to state the problem.The problem is obviously that the light will not come on. The second part of the scientific method would be to make observations about the past statement. Obviously the light will not come on so I would look across the room to see if other electrical devices are working in order to determine if the supply of electricity into the house is flowing and it is judging by the glowing lamp on the side table. The switch seems to be operating judging by feel and sound of the clicking noise as the switch is operated.
I look up and do indeed see a bulb screwed into the light fixtured. It appears that the light should come on when the switch is activated. The third part of the scientific method would be to state a hypothesis: If I replace the light bulb with a new one, then the light should come on. I then acquire a new bulb from the pantry and attempt to execute my expierement. The new bulb also did not come on when the switch was activated. Since I have replaced the old bulb with a known new and operational bulb, I know the bulb is not the problem.Since my hypothesis did not appear to be true, I must come up with another: If I replace the switch, then the light should come on.
At this point, I know that electricity is flowing into the structure and there is an operationally known bulb now in the fixture. The only variable could be the switch which is responsible for interrupting the current flow in order to control the light. I proceed to replace the switch and after it is replaced, viola, the light comes on. My second hypothesis was true and the switch was the problem to the dark entry.The next problem is a problem that the scientific method can be applied to and that we all can relate to: ? The car will not start when the key is turned. The scientific method indicates that one must first state the problem which is that nothing happens when the ignition key is turned in order to crank the car. Upon opservations, none of the interior lights of the car are coming on either.
The car does make a clicking sound when the key is turned which indicates that there is some electricity in the battery.A hypothesis: If I replace the battery in the car, then the engine should rotate and start. After executing the hypothesis and replacing the battery, the engine does start and runs. The engine runs form quite some time but then dies and the same problems as stated in the observations appear again. Since the battery is now know to be good, we know that this is not the problem. Upon further research, the recharging system in the car could be bad and is not recharging the battery.A new hypothesis: If I replace the alternator, then the battery should stay charged and the car should always start right up.
After the battery has been charged and the alternator has been changed, the car starts up and runs as well as the battery showing signs of being recharged. These two examples of the scientific method show that the method is used to continuously dissect situations until the correct problem or observation is noticed and can be addressed by the person using the method.The scientific method is still used today by many scientists. To say we can live without science is to say we can live without air to breath. Science embodies everything we humans come in contact with everyday of our lives. Most of us go through our daily lives and do not pay any attention to science but it is still always there. The following is a typical day in my life and the science that I come in contact with.
