Q: Summarize the steps of the scientific method. Describe an experiment of your choice, which demonstrates the basic considerations that must be taken in the design of a good, manipulative experiment. Now that you know some details of how scientists solve problems, how might you apply that knowledge to your daily life?

A: The scientific method is one of the most if not the most important method that scientists use to learn about the earth. The goal is to apply the scientific method to determine a cause and effect relationship. The scientific method is made up of five detailed steps, these steps are:

I. Make an observation

A scientist sees something that he cannot explain, but is very interested and would like to explain the phenomenon.

II. Ask Questions

After the observation is seen, the scientist comes up with a group of questions such as who, what, where, why, and how. These questions significantly help the scientist narrow down the effects of the phenomenon.

III. Develop a Hypothesis

A hypothesis is a proposition set forth as an explanation for the occurrence of some specified group of phenomena, either asserted merely as a provisional conjecture to guide investigation or accepted as highly probable in the light of established facts. This hypothesis must have the ability to be either true, or false.

IV. Make Predictions

If the hypothesis is correct, scientists will make a prediction on how they think the experiment will end. This helps them have a starting point if the hypothesis is correct.

V. Test the Predictions

Experimental tests may lead to the confirmation of the prediction, or to the corruption of a prediction. If the hypothesis is not correct, the scientific method requires that the hypothesis must be modified. The prediction must agree with the experiment to believe that it is a valid description of nature.

A great experiment that demonstrates the basic considerations that must be...
