Scientific Method Case Study: Resolving a Lawn Problem
Introduction
The scenario for this case study is that you notice that the grass around my house is brown, short, and dead. The grass around my neighbor's house is green, tall, and alive. Utilizing my understanding of the Scientific Method, my intent is to explain what the problem is to develop a hypothesis. After developing the hypothesis I will then design and perform an experiment to test my hypothesis; analyze my data and reach conclusions regarding my hypothesis. I will discuss various ideas regarding watering and fertilizing methods and the type of environment required that will help produce healthy growth in my yard.
The Scientific Method Traditionally, there is a series of steps used by all scientists to study natural occurrences. Some problems lend themselves to solution by designing experiments; others are solved by detailed observation of processes or structures. The scientific method is an objective process that helps ensure accurate observation. Scientific Method is defined as a system (step by step process) of thought and procedure that reflects how scientists define and study a problem. (1) There are several steps used in the Scientific Method:
1. Recognize a question or a problem. State the problem as a question.
2. Develop a hypothesis. A hypothesis is defined as a tentative proposition suggested as a solution to a problem; a statement of the researcher's expectations about the relationship among the variables of the study. Basically it is a prediction about what will happen.
3. Design and perform an experiment to test your hypothesis. Plan how you will test your hypothesis.
4. Analyze the data and reach conclusions about your hypothesis. Summarize your findings.
