Electricity

Chapter 9: Electrostatics
In Chapter 9 students investigate the properties of electric charges and learn about the model for the electrical nature of matter. Students then learn three methods of charging objects and develop an understanding of the effects produced when electric charges interact with electrical insulators and conductors. They investigate some of the ways to remove electric charge from objects and identify how these methods are used in everyday life. The practical applications and ways of controlling some of the hazards related to static electricity are introduced and explained.

Chapter 10: The Control of Electricity in Circuits
This chapter focuses on the functions of the different parts of an electric circuit, the introduction of electric potential (voltage) through the study of dry cells and batteries, and electric current. The emphasis then moves to the study of electrical loads and the investigation of electrical resistance. Finally, the two basic kinds of electric circuits are studied, and the characteristics of series and parallel circuits are determined by investigation.

Chapter 11: Harnessing Electrical Energy
This chapter focuses on developing an understanding of electrical energy and power and the many kinds of energy sources that are used to produce electrical energy. Students are first introduced to the concept of energy by using batteries to understand the factors that can be used to calculate the amount of scale energy production to the large-scale methods used in the many electrical generating stations.

Chapter 12: Using Electrical Energy Safely and Efficiently
In this chapter students learn how to describe and explain the operation of household electrical wiring systems, and the importance of safety when using electricity and electrical devices. They learn the relationships between electrical energy, power, and time interval, and calculate electrical energy and the efficiency of electrical transformations. Students conduct a family energy audit and suggest ways to reduce energy consumption. Students are given the opportunity to create a plan to use renewable energy resources to meet the needs of a dwelling, farm, or small community.
