This document discusses current electricity and circuits. It defines current electricity as the flow of electrons through a conductor. It explains that circuits must be complete loops with a power source, wires, and a device in order to work and that conductors allow the flow of electricity while insulators do not. Switches are described as opening or closing circuits to control the flow of electricity. Links are provided to online activities about circuits and a quiz.

2. Objectives Learn: Circuits must be complete in order for them to work properly. Do: Identify the components of a complete circuit. SIF: You can create a complete circuit by selecting different conductors.

4. Current Electricity Electricity runs many objects in our everyday life. What are some objects that use current electricity? Current electricity is the flow of electrons through a conductor (Furgang, 2004). How would life be different if we didn’t have electricity?

5. Current Electricity is All Around Us (Discovery Education, 2008)

6. Circuits All current electricity flows through circuits. Circuits are closed paths where the electrons can flow through (Furgang, 2004). If there is a break in the circuit the electrons will no longer flow. Draw a picture of a closed and open circuit.

7. Circuits All circuits must include an electricity source like a battery, wires that are made from conductors, and something that needs electricity like a light bulb (Furgang, 2004).

8. Conductors Conductors allow energy to pass through freely. Metals Water Heated Gases Human Body

9. Insulators Insulators do not allow energy to pass through freely. Glass Rubber Plastic Wood

10. Switches Why do we have light switches? How do you think they work? The job of a switch is to open or close a circuit. Let’s look inside to see what is happening.
