4. My homemade flashlight
We made it out of a battery, two wires and,
and light bulb.

5. Why does a light bulb stop
burning?
The reason why the bulb stops burning because
the light bulb runs out of gas.
HTTP://www.bing.com/images/search
Burned out light bulb.

6. How does a light bulb work?
The light bulb has to be connected to 2 wires
and to an energy source. The positive and
negative current flow to it causing the
filament to light up.

7. Who invented the light bulb?
Thomas Edison invented the light bulb.

8. Insulators
Any material that does not let electricity pass
through it.
Work sheet
Wood
Plastic bag

9. Conductors
Keeps the flow of electricity.
Examples
Power line
Air vent
penny

10. Series circuit
A series circuit is a circuit that can run on
more than one bulb. If you unscrew one the
light bulbs they will all go out.

11. Parallel circuits
A parallel circuit connects each bulb and if
you unscrew one light bulb the other ones
stay lite.

12. Comparing
The parallel and series circuit are similar because
they both can have 2 or more light bulbs.

13. Contrasting
The series and parallel are different because
Series Circuit Facts:
Parallel Circuit Facts:
Both bulbs are on
the same circuit Each bulb is on a different circuit
Both bulbs go out Only the removed light bulb goes out
Brightness dim
Brightness Bright

14. How does static electricity work?
Positive and negative electrical charges that are
separated from each other ,and are not moving
they don't get electricity to pass though them.

15. How does lightning work?
Negatively charged clouds create static
electricity and strikes to the ground when it
gets too hot.
