Designed to provide the ideal solution for teaching junior science, "New Star Science 4" books are aimed at the fourth primary school year. These teacher's notes provide a background to the unit as well as photocopiables and assessment material. The focus of this text is "circuits and conductors".

Middle-graders often wonder how electricity is transmitted and how we are protected from being shocked. Pegis takes these readers along on an exploration of the roles conductors and insulators play in the transmission.

This book briefly describes the functions of conductors and insulators in electricity.

Electricity and Magnets Electrical Circuits • Understand the elements that are needed to crate an electric circuit • Distinguish between the features of a series and a parallel circuits Conductors and Insulators • Review of the parts of a simple circuit • Understand the terms conductor and insulator • Explore the properties of various materials as conductors or insulators Magnets • Recognize and describe magnets, their poles, properties, and uses • Categorize materials that will or will not attract to a magnet • The earth as a magnet introduction Electromagnets • Discover how to crate electromagnets, and how the strength of an electromagnet can be altered by changing elements such as the number coils and the strength of the current. • Recognize how electromagnets differ from permanent magnets, and be able to identify examples of where electromagnets are used in daily life

Introduces electric circuits, discussing the different types, their parts, and how they work.
