# PS.11 a - Electricity

The student will investigate and understand basic principles of electricity and magnetism. Key concepts include

a) static electricity, current electricity, and circuits.

Bloom's Levels: Analyze; Understand

### BIG IDEAS

• Electricity is a form of energy that makes many modern conveniences possible.
• Energy exists in many forms and has the ability to do work or cause a change.

• I can explain why my clothes sometimes stick to me, especially in the winter.

### UNDERSTANDING THE STANDARD

• Several factors affect how much electricity can flow through a system. Resistance is a property of matter that affects the flow of electricity. Some substances have more resistance than others.
• Friction can cause electrons to be transferred from one object to another. These static electrical charges can build up on an object and be discharged slowly or rapidly. This is often called static electricity.

### ESSENTIALS

In order to meet this standard, it is expected that students will

a)  design an investigation to illustrate the effects of static electricity.

construct simple circuits to determine the relationship between voltage, resistance, and current.

### KEY VOCABULARY

static electricity, current electricity, series circuit, parallel circuit, magnetic field, electric current, motor, generator, voltage, resistance, current, direct current, electromagnet, conductor, alternating current, insulator
