Chapter 3 – Get a Charge Out of Matter

1. Chapter 3 – Get a Charge Out of Matter

2. Chapter 3: Get a Charge Out of Matter • Create a Chapter 3 Title Page in your notebook. • Goals: • What happens when atoms interact with other atoms? • How does chemical bonding explain properties of different compounds? • How does bonding within molecules affect interactions between molecules? • How can different models of microscopic behavior help explain the macroscopic behavior of compounds?

3. Engage: What’s Shocking Create a new title/thread “What’s Shocking?”. Update your Table of Contents with the correct page number. Learning Target: I can recall what I know about the electrical nature of matter by predicting what will happen with a conductivity tester in different solutions.

4. Engage: What’s Shocking Read Introduction p. 102 P&P 1: Sketch each beaker, and label it with the name of the substance, and the chemical formula. P&P#2: Predict which substances will conduct electricity. Sketch the conductivity meter in your notebook with a brief explanation of how it works.

5. Engage: What’s Shocking • P&P#5: Make a list of as many conductors and insulators as you can think of. • Conductor: a material in which heat, electrical charge, or both can flow readily. • Insulator: a material that is a poor conductor of heat, electrical charge, or both. • P&P#7: Record your observations as we use the conductivity meter in each of the solutions. • What do you think causes some substances to conduct electricity, while others do not?.

6. Engage: What’s Shocking What do you know about Vandegraaff generators? Let’s see what happens when we put different things on the Vandegraaff generator... Let’s take a closer look at how the generator works http://www.virlab.virginia.edu/VL/VDG.htm/state/4
