1 Starter: Directions: Copy the questions and answer the questions. You will have to answers for each questions. Use the following terms to answer the question: Conduction/Induction, Repel/Attract 1.A positive glass rod on a string is brought near another positive glass rod on a string. What will happen when the two come in contact with each other. What type of charge transfer is happening between the two glass rods.

2 Review Directions: Draw and Classify Which One has an Overall Positive Charge, Overall Negative Charge, or Overall Neutral a.+ - + + b. + - + - + c. - + - - - + - + - + - + - + - + - -

3 Review Directions: Draw and Identify as Repelling or Attracting. - - + - + +

4 Review Explain what is happening.

5 What is this a picture of? What are the three parts of an atom? Which two are found inside the nucleus? Which one is found outside the nucleus?

6 Conductors vs. Insulators ConductorInsulator Allow electricity to Resist the flow of flow through. Electricity. Keeps electricity out. Examples: Any Metal, Examples: Rubber, Metal Wire Wood

7 Conductor or Insulator Directions: Copy and Answer using the terms insulator or conductor. 1.Silver8. Aluminum 2.Wood 3.Air 4.Glass 5.Copper 6.Gold 7.Styrofoam

8 Batteries=Produce Voltage (Potential Difference) A.Dry cell – Has positive and negative terminals. Electrons flow from the positive terminal to the negative terminal.

9 B. Wet cell - Contain metal plates placed in a chemical solution (electrolyte). Ex.: Car battery

10 Resistance=Resistors slows down the speed of electrons flowing through wire. (Dims Lights)

11 Current Moving electrons; moving negative electrons through the wire to the resistor (light).

12 Electricity Book

13 Circuits Directions: Using your worksheet draw a simple open circuit with 4 light bulbs, 1 battery, 3 resistors, 1 switch and wire. AND A closed circuit with 2 light bulbs, 1 battery, 2 resistors, 1 switch, and wire. Your light bulbs and resistors should NOT be together separate them.

14 Circuits 1.Series circuit – only one path for the electricity 2. Parallel circuit – More than one path for the electricity with each branch having the same potential difference. 3. Complex circuit – contains both series circuits and parallel circuits
