PART I: SCIENTIFIC METHOD Scenario 1: 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?   Observation: I switched the Lights on and nothing still dark. Question: Why isn’t the Light cutting on? Hypothesis: Light Bulb is blown Experiment: Change the bulb and see if a new bulb will work. Analysis: Changed the bulb and the light came on Conclusion: The Hypothesis is not rejected I put the new light bulb in the lamp and the light came on so the hypothesis is true. If this doesn’t work I will start over with another Hypothesis. Hypothesis: Maybe there is a power outage. Experiment: I can look around to my neighbor’s houses and see if they have lights. Analysis: Looked around at my neighbors houses and they do not have lights either. Conclusion: The Hypothesis is not rejected since the neighbors do not have lights either so the hypothesis has proven true. Scenario 2 : I walk outside to go to work open my car door go to start up the car and it will not start. Now what? Observation: I turn the key in the ignition but the lights do not cut on and the engine does not turn over. Question: Why isn’t my car starting up? Hypothesis: I think since the lights are not turning on and the engine is not turning over then the battery is dead.
Experiment. I will get a friend to come over a jump start my battery. Analysis: My Friend jump started my car and the engine fired up. Conclusion: My Hypothesis cannot be rejected I need a new battery since the engine started right up after being jump started.
