2. Static Electricity
This is an electrical charge that builds up on a material
Static electricity is present on some materials such as your hair, or a comb.
These charges can build up and cause a discharge, causing a shock, especially when it is cold outside.

3. Before Static Discharge
A negatively charged object, (my hand) is attracted to the positively charged object (the door knob).

4. During Discharge
When the two objects come into contact, the oppositely charged objects exchange particles and a shock is produced.

5. After Discharge
After the discharge the two objects return to their original neutral state.

6. Conductors and Insulators
Conductors are materials that negatively charged particles flow through easily.
An example of negatively charged particles would be an electrical current.
Examples of some conductors are silver, gold, copper, and water

7. Examples of Conductors
COPPER
WATER
GOLD
SILVER

8. Insulators
Insulators are materials that electric charges do not flow through easily.
Some examples of insulators are rubber, glass, wood, plastic, and air.

9. Examples of Insulators
PLASTIC
WOOD
RUBBER
AIR

10. Circuits A circuit is the pathway that an electrical current follows.
The three items needed for an electrical circuit are a light bulb, wire and a battery.

11. Types of Circuits There are three types of circuits:
Open or incomplete circuit
Closed or complete circuit
Switch circuit which can be complete or incomplete

12. Incomplete Circuit
An incomplete, or open circuit, has a gap which does not allow the electricity to flow through the wire from the battery and light the bulb.

13. Complete Circuit
A complete circuit is one in which there are no gaps. In this kind of circuit electricity flows without stopping through the wire from the battery to the light bulb and lights it up.
COMPLETE CIRCUIT

14. Switch Circuit
A switch circuit contains, in addition to three items needed for the other two circuits, a switch that can be opened to stop the electrical flow or closed to allow the electricity to flow and light the bulb.
SWITCH CIRCUIT

15. Two Types of Switch Circuits
There are two types of switch circuits:
Series circuit – in this kind the parts are connected so that the electric current passes through each part one after another along a single pathway
Parallel Circuit – in this type the current passes along more than one pathway

16. Bar Magnets and Electromagnets
There are two main types of magnets that are used by people BAR MAGNETS and ELECTROMAGNETS.

17. Information on magnets
A magnet is an object that attracts iron and other certain metals.
The force of a magnet is stronger at two areas called the magnetic poles

18. Electromagnets
Electromagnets are strong temporary magnets that are created by electricity running through a wire or other conductor.

19. Electromagnets Electromagnets attract objects that are made of iron.
The advantage to this kind of magnet is that it can be turned on and off.
Electromagnets have no poles.

20. Bar Magnets

21. Bar Magnets
Bar magnets are permanent magnets. This means that they keep their magnetism for a long time.
The earth is like a bar magnet because it has two magnetic poles.

22. Bar Magnets
Bar magnets have two unlike poles, their force of magnetism is stronger at each pole.
Unlike poles attract one another, and like poles repel one another.
