### Transcript

• 1. Electricty/Energy
Vocabulary & Terms
• 2. Static Electricity
• When you take off your wool hat, it rubs against your hair.
• 3. Electrons move from your hair to the hat.
• 4. A static charge builds up and now each of the hairs has the same positive charge.
• 5. Remember, things with the same charge repel each other. So the hairs try to get as far from each other as possible. The farthest they can get is by standing up and away from the others. And that is how static electricity causes a bad hair day!
• What is a conductor?
• 6. Conductors
Allows electric energy/current to flow through it
Best conductors are
Silver
Gold
Copper
Is Water a Conductor?
• 7. What is an insulator?
• 8. Insulators
Restrict (stop or limit) the flow of electricity through it
Some insulators are:
Paper
Plastic
Glass
Ceramic
• 9. How a Wire Works…
• 10. A Battery is…
A container full of chemicals that produce electrons. These electrons produce energy.
Where do you use batteries?
• 11. Light Bulb
Turns electricity into light through
the filament inside the glass bulb.
What is the insulator?
What is the conductor?
• 12. Types of Circuits
Open Circuits
Closed Circuits
• 13. Series and Parallel Circuits
• In a series circuit, both bulbs are connected in a row, with electricity passing first through one then the other.
• 14. In the parallel circuit, electricity passes through both bulbs at the same time.
• 15. A major advantage of parallel circuits is that if one bulb malfunctions, the other bulbs continue to function.
• 16. In a series circuit, when one bulb breaks, both bulbs stop working.
• Which is Which?
Series Circuit
Parallel Circuit
