Bài giảng Electricity as energy

Learner Expectations:

Content Standard: 14.0 Energy

The student will investigate energy and its uses.

Learning Expectations:

14.3 Recognize the basic concept of electricity.

How is Electric Energy Produced?

Atoms are made up of protons, neutrons, and electrons. The electrons have a negative charge and can move freely.

For example, rubbing two objects together can cause electrons to move from one object to another. This movement of electrons is called ELECTRICITY !

Electricity as Energy 
Write On Grade 5 
Learner Expectations: 
Content Standard: 14.0 Energy 
The student will investigate energy and its uses. 
Learning Expectations: 
14.3 Recognize the basic concept of electricity. 
In this activity you will: 
Learn about electricity as a form of energy. 
What is Electric Energy? 
A form of energy where the electrons flow, which carries electric energy from place to place. 
How is Electric Energy Produced? 
Atoms are made up of protons, neutrons, and electrons. The electrons have a negative charge and can move freely. 
For example, rubbing two objects together can cause electrons to move from one object to another. This movement of electrons is called ELECTRICITY ! 
How do electrons move? 
Electrons move in two different ways: They can jump through the air as sparks or they can flow smoothly. 
When electrons flow smoothly, they make an electric current. 
What is the difference in conductors and insulators? 
Conductors allow electricity to flow through very easily. Metals and humans are both conductors. 
Insulators do not allow electricity to flow through easily. Rubber, glass, and plastic are all good insulators. 
Types of Circuits 
The two types of circuits are called open circuit and closed circuit. 
In order for electric current to flow, the circuit must be CLOSED! 
A switch controls the opening and closing of a circuit. Example: flashlight 
Writing Activity 
Write a paragraph about electric energy. Include the following: 
What is electricity? 
How is it produced? 
What are the two types of circuits? 
What are some ways that you use electricity every day?
