Presentation transcript:

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.

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

Review Directions: Draw and Identify as Repelling or Attracting

Review Explain what is happening.

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?

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

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

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

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

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

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

Electricity Book

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.

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
