Lesson 13 - Conductors and Insulators

Introduction

Not every atom is created equal. The structure varies from atom to atom. Some atoms are incapable of holding their outer electrons together. They are called free electrons because they can roam freely from atom to atom. These electrons pass electrical energy from one particle to another thereby transferring energy in the form of electricity. A conductor is a substance in which electrical charges can flow through. In contrast, an insulator resists electricity. Let’s study the difference between the two.

Conductors and Insulators

In your Science Journal:

    1. Write down today’s Lesson Title at the top of your next Journal page.
    2. Write today’s learning objective on the first line.
    3. Explore the Module 8 - Lesson 13 presentation below. Today, we’ll learn about materials that allow the flow of electricity - conductors and materials that resist the flow of electricity - insulators.  We’ll be exploring a Google Slides presentation. It is a presentation that will help you understand conductors and insulators.
    4. Write down the important terms and their definitions and important diagrams (yellow boxes) in your Science Journal.

 

Video

Check out this video where kids use a variety of materials that make good conductors, including aluminum foil and a coat hanger, and find out how difficult it can be to complete an electric circuit.
