The BIG Question:
How is current
electricity produced?
•something must touch the positive and negative terminal of the battery•something must touch the threaded base and the tip of the bulb•current electricity can only flow from negative to positive

The circuit is closed.
Electrons flow through the filament and
produce light.
The filament is broken. The circuit is open and no electrons
can flow.
The BIG Question:
How can I control the electricity
flowing through a circuit?
A switch can be used to open and close a
circuit.
. .
2. Draw a picture of your circuit on the top
half of your sheet.3. Use your switch to open your circuit. Then work on your Electricity
Challenge Packet or study your flash cards.
1. Build a switch that will allow you to easily
open and close your circuit.
