- Content Standard: 14.0 Energy
- The student will investigate energy and its uses.
- Learning Expectations:
- 14.3 Recognize the basic concept of electricity.
|
|
3
|
- Learn about electricity as a form of energy.
|
|
4
|
- A form of energy where the electrons flow, which carries electric energy from
place to place.
|

|
- 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 !

|
- 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.

|
- 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.
|
|
8
|
- 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
