Static Electricity 1. Matter is made up of particles that have mass & volume. 2. Particles of matter also have a property called an electric charge. 3. A particle can have a positive (+), negative (-), or no charge.

Static Electricity 4. Normally, objects have an equal number of positive & negative particles (neutral). 5. Rubbing two objects together can move negative particles from one object to another.

Static Electricity 6. A charge is measure of extra positive or negative particles an object has. 7. Rubbing can give one object an overall positive charge, and it gave the other an overall negative charge.

Static Electricity 8. The charge that stays on an object is called static electricity. 9. Static means ‘not moving.’

Current Electricity 10. A flow of electricity is called an electric current. 11. A current is measured in amperes, or amps. 12. An amp is a measurement of electrical current in a circuit.

Current Electricity 13. A flow of electrical charges is called an electric current. It is like a moving stream. 14. An electrical circuit is a closed path that electrical current follows.

Current Electricity 15. Volts are a measure of force, or pressure, behind the current. 16. Watts are amps times (x) volts. This derives the total measurement of power

Current Electricity 17. A path that is made for an electrical current to flow is called a circuit.

Current Electricity 18. A battery is an electric cell, which supplies energy to move charges through a circuit.

Current Electricity 19. The energy a battery provides is measured in volts. 20. A material that a current can pass through easily is called a conductor.

Current Electricity 21. Most metals are good conductors. However, other materials can conduct electricity as well. 22. A material that cannot pass a current easily is called a insulator.

Current Electricity 23. A switch uses conductors and insulators to make a circuit. 24. When a switch is on, two conductors meet and the circuit is complete.

Current Electricity 25. When a switch is off, air separates the conductors, breaking the circuit. 26. Some materials cut down, or resist, the flow of charges. These materials are called resistors.

Series Circuit 28. A current that has only one path to follow is called a series circuit.

Parallel Circuit 28. A parallel circuit has more than one path to follow. If the current stops flowing in one of the paths, the flow will continue through the alternate circuit.
