It has parts, right? Wires

Can you name its parts?

Correct, very good!

D. Discussing new concepts and practicing
new skills #1
The word electricity is derived from the
Greek word “elektron” which means amber.
Electricity is thought to have been discovered
in ancient Greece when someone rubbed a
piece of amber and it picked up light
materials such as feathers and hair. This is
possible due to the fact that friction can
generate electricity.
Again, what language does electricity
come from?
From Greek word, teacher.
What is the Greek word for electricity?
Elektron, teacher.
So, what does “elektron” mean?
Amber.
Very good, let us now move on to the
kinds of electricity.
There are 2 kinds of electricity, static
electricity and current electricity.
Static electricity is produced when
electrical charges build up on the surface of a
materials, usually as a result of friction or
rubbing of materials together.
Current electricity id produced by the
continuous flow of electron.
Again, what are the 2 kinds of electricity?
Static electricity and current electricity.
Correct!
Alessandro Volta, an Italian scientist,
discovered current electricity. It is made up of
moving electrons that flow through electrical
wires connected to lights, machines, or
appliances to make theses devices work.
Current electricity is the kind of electricity
that we often use in many activities. It flows
through a complete circuit.
Again, who discovered current electricity?
Alessandro Volta
An electric circuit is a network that has a
closed-loop, giving a return path for the
current. There are two types of circuits, the
series circuit and parallel circuit. We will
discuss first the series circuit.
So before we start discussing the series
circuit, let us familiarize some basic terms
first:
Current- it refers to the flow of electrons.
Electricity has work to do, and when the
electrons are flowing around a circuit, that’s
current at work.

Do you understand?

Circuit- a closed continuous path for Yes, teacher.

electricity to flow. It is composed of power
source, connecting wires, load, and switch.
 Understand?

Resistance/resistor- the restriction or Yes, teacher.

opposition to the flow of electric current. This
is what electricity encounters when it flows
along with physical material.

Understand?

Voltage- it is the measure of work required to

move a unit charge from one location to
another, against the force which tries to keep
electric charges balanced. In the context of
electrical power sources, voltage is the
amount of potential energy available per unit
charge, to move charges through a conductor.
Do you understand?
Yes, teacher.
Very good! Let us now move on to the
parts of an electric circuit.
A circuit has three components. These are
the conductor, the source and the load.
1. Conductor- serves as the pathway for
the electrical current to pass from the
 source to the different
parts/components in a circuit. (ex.
Connecting wires) Yes, teacher.

2. Source- contains positive and

negative electrons. It is the source of
electrical energy in the circuit. (ex.
Dry cell or batteries)

3. Load- it determines if the electricity

that flows in the circuit is closed or
complete. (ex. Bulb)

Do you understand?

Again, what are the three components of a

circuit?

Correct! Very good!

There are 3 kinds of electric circuits based
on the connections;
1. Series circuits
2. Parallel circuits Yes, teacher.
3. Combination circuits
For our lesson, we will just focus on the
series and parallel circuit. Conductor
Source
For now, we will discuss first about the Load
series circuit.
A series circuit is a circuit that allows
electric current to flow through a single path.
The available electric current flows through
each load but there is only one complete path.

If one bulb is loose or does not work, the

circuit is open, and the current is open, and
the current does not flow. The rest of the
bulbs will not light. The defective bulb has to
be replaced, or the loose bulb should be
screwed tight for the current to flow again.
Do you understand?

For the devices in a series circuit to work,

each device must work. If one goes out, they
all go out.
Changing the type of components in series
circuit has an impact on the circuit’s all over
performance. When it comes to how current
and resistance operate in series circuit, there
is universal rule to remember: the more work
(resistance) a series circuit does, the more its
current will decrease.

 Increasing

Do you understand?

What will happen if we increase the

number of bulbs in a series circuit?

Correct! Very good, students.

Yes, teacher.

More power will be decreased form the

battery.
E. Discussing new concepts and practicing
new skills #2
 To test if you truly understand our topic
today, you will be having a group activity. I
will divide you into 2 groups. Each group will
have to create a series circuit.
Materials needed:
 Two 1.5 V AA dry cells
 Two pieces of 6 V bulbs (used in
flashlight)
 1meter copper wire or connector wire
 Electrical tape
 Pliers
What to do:
1. Gather all the materials needed.
2. Cut the wire into 4 pieces
3. Carefully remove approximately ½
inch of the insulation from both ends
of all your wire pieces.
4. Attach one of the wires to the positive
terminal of the dry cell. Connect the
other side of the wire to the either side
of the bulb socket.
5. Attach another wire to the other side
of the bulb socket to connect another
bulb socket.
6. attach another wire to connect either
side of the last bulb socket.
7. Attach another wire to connect the
other side of the bulb socket to the
negative terminal of the dry cell.
8. Observe and study the light of the 2
bulbs.
9. Detach any of the bulb form a socket.
Observe what will happen to the other
bulb.
10. Without disconnecting the bulbs,
connect another dry cell to the first dry
cell. Observe the flow of energy when
another dry cell was added.
F. Developing mastery (Leads to Formative
Assessment)
Study the picture. Put a label on each part
of the series circuit. Identify whether it is the
conductor, the source, or the load.
 1. _______
2. _______
3. _______

G. Finding practical applications of

concepts and skills in daily living
As a student, what is the importance of
learning series circuit in your everyday life?
We can use our knowledge about series
circuit in some situations, like for example,
when a power shortage occurs. I will be able
to create an improvise light using only
batteries, wires and bulbs.
That’s right! What else?
We can also use our knowledge about it in
order to save electricity.
Very good!
