Informative Speech Outline

I. Introduction

A. Attention Getter: Jane Brox said, “Time and task were both disorienting. For if you were to remove everything from our lives that depends on electricity to function, homes and offices would become no more than the chambers and passages of limestone caves… simple shelter from wind and rain. No way to keep out cold, or heat, for long. No way to preserve food, or to cook it. The things that define us, that without their purpose, they lose the measure of their beauty and we are left alone in the dark with countless useless things.” (Jane Brox, Brilliant: The Evolution of Artificial Light)

B. Thesis Statement: Today I will inform you about the significance of electricity and the role it plays in our everyday lives. In 2006 Laura Robertson from http://ngm.nationalgeographic.com (Which has been around since 1888), stated that the United States of America is the world's second largest producer and consumer of electricity. It consumes about 20% of the world's supply of electricity, with California as the greatest consumer of all the states.

C. Preview: First, I will talk to you about the beginnings of electricity, and the scientists who have helped evolve it into what we use today. Second, I will talk about what humans are trying to accomplish by harnessing and using electricity for our personal gain. Thirdly, I will be talking about electricity’s legacy and impact on human civilization.

Support: On October 1, 1995 the Media & Public Communications Office of the Commission, at http://www.energyquest.ca.gov (Which is the award-winning energy education website of the California Energy Commission.), stated that Gilbert wrote about the electrification of many substances in his "De magnete, magneticisique corporibus". He also first used the terms electric force, magnetic pole, and electric attraction.

b. Impact: This shows us that Gilbert was one of the first people to recognize the significance of electricity.

b. Impact: This was the birth to modern day power plants and nuclear power plants/generators due to the demand of people wanting electricity.

Transition: Now that I have told you a brief history of electricity and the people who helped discover it, I am going to talk about how scientists began to harness and use electricity to our advantage.

B. Topic Sentence: Scientists soon realized that the world could harness and use the power behind electricity for our own personal gain, and there are many examples of this in today’s society, such as.

1. Claim: The telephone and the telegraph are used by almost everyone these days....
