On your own do your best to complete
Flow of Electricity worksheet
Assign Getters, Reporters, Coaches, and
Recorder for each group of 4
Choose a number 1 – 4
Recorder – 1,Getters – 2, Reporters – 3,
Coaches - 4

Getters get 2 light bulbs
This is the light bulb we will use. It
is the kind of light bulb you might
find in a flashlight. Let’s start by
observing it for a minute. Create a
circle map of your observations.
Recorder write down group results
Reporter choose 2 to share with
class

Getters get 2 D-cells and 4 wires
Can you use a battery to turn on
the light bulb?
In Pairs try and light the bulb with
just the light bulb and battery
Show me how you tried

Where did you connect the wires to
the battery?
Where did you connect the wires to
the light bulb?
What happens when you touch the
wire to the glass part of the bulb?

Getters – 2 light bulbs, 2 wires, 2 d-cell
batteries
Can you light a light bulb with just one
wire and a battery?
Raise your hand if you are successful
Draw a picture of your circuit and include
arrows showing the “flow” of electricity
through the circuit
Hint: Negative is location of extra
electrons, Positive is lacking electrons
If electrons behaved like water which way
would it flow?

Electricity Receiver
Anything that uses electricity to do
something is an electricity receiver.
The light bulb produces light when
it received electricity as it flows
through he whole circuit.

Draw Bulbs and Batteries
Trace the flow using Circuit and
Components
What general shape am I tracing
Electricity and Magnetism
Study the Filament
The part of the bulb that makes light
is the filament. When electricity
goes through the filament, it gets
so hot it gives off light.

Getters return equipment
You can’t see electricity. How do you
know when it is flowing in a bulb
circuit?
How did you get the bulb to light
with only one wire?
