What distinguishes science from other fields of study is the way in which science seeks answers to questions. In other words what separates science is an approach called the scientific method.

History Beginning in Ancient Greece with philosopher Aristotle using a method of induction, reasoning, observation and measurement with all of his research. This led to the organization of similar reasoning lending way to the different fields of scientific study.

Middle Eastern (Muslim) influence added to the scientific method Aristotle used. Scientist Islamic al-Haytham developed a scientific method of: stating the problem testing a hypothesis through experimentation Interpreting data to reach a conclusion Publishing the results

During the Renaissance Period scientist Roger Bacon used the same method adding the repetition of the experiment.

Galileo used the existing steps adding that empirical data could not be obtained from every experiment, therefore, through repetition the repeated outcomes could stand as a theory.

The method was so strong in its effectiveness that it remained in tacked until the 20th century. Scientist Karl Popper found that a set list of steps does not work with all types of experimenting. He found that the scientific method with its limitations should be a guide and not a rule.

The basic steps in the scientific method are: 1. Stating the problem 2 The basic steps in the scientific method are: 1.Stating the problem 2.Gathering information on the problem 3.Forming a hypothesis 4.Performing experiments to test the hypothesis 5.Recording and analyzing data 6.Stating a conclusion 7.Repeating the work

Stating the Problem This is the first step. Determine what it is you want to experiment and why. This can also be in the form of a question.

Gathering Information on the Problem The next step would be to research information related to your problem.

Forming a Hypothesis Using all information that has been gathered develop a suggestion of a possible answer/solution.

Performing Experiments to Test the Hypothesis Evidence that will either support or disprove a hypothesis much be found. The hypothesis must be tested to show whether or not it is correct. Experiments follow set rules that will ensure the correct answer. This would be similar to a recipe when cooking.

Variable This is the factor that is being tested. Only on variable should be tested at a time. A control must be present as well (an aspect of the experiment that stays the same)

Recording and Analyzing Data Gathering / recording information that is collected during experimentation. This can be numbers or observations Analysis occurs when this information is placed in a chart, table or diagram.

Stating the conclusion Answering the hypothesis giving evidence gathered during experimentation as your defense for your answer.

Repeating the Work Allows for the work to be verified. Repeating an experiment concluding with the same evidence makes the answer reliable.

Communicating Results A report of the experiment findings should be detailed enough so that scientists through out the world can repeat the experiment for themselves ending with the same result https://www.youtube.com/watch?v=i8wi0QnYN6s

Changing Factors Scientists use an experiment to search for cause and effect relationships in nature. In other words, they design an experiment so that changes to one item cause something else to vary in a predictable way.

These changing quantities are called variables These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent Dependent controlled.

Independent Variable An independent variable is the variable you have control over, what you can choose and manipulate The independent variable is the one that is changed by the scientist. To ensure a fair test, a good experiment has only one independent variable.

Dependent Variable A dependent variable is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it "depends" on the independent variable The scientist focuses his or her observations on the dependent variable to see how it responds to the change made to the independent variable.

Control Experiments also have controlled variables. Controlled variables are quantities that a scientist wants to remain constant, and he must observe them as carefully as the dependent variables.
