3. 1. Sit Properly
2. Listen to the teacher carefully
3. Keep quiet.
4. Raise your hand if you want
to answer.
4. A circuit is a route in which electrical current can flow.
SIMPLE ELECTRIC CIRCUIT
5. LESSON OBJECTIVES
Cognitive Domain
A. Define close and open circuit.
Affective Domain
B. Appreciate how the light bulb works and the
importance of electrical circuit in everyday life.
Psychomotor Domain
C. Demonstrate the ability to manipulate electric
circuit to effectively light a bulb.
9. Simple Electric Circuits
SWITCH
The switch controls the
flow of electricity, it allows
or stop the flow of electric
current from the source to
the load or bulb.
12. A close circuit makes
the bulb light up
because the path of
electric current or
electricity is
complete, allowing
the electricity to flow
through it.
13. Electricity does not
flow in this kind of
circuit because there
is a gap from one end
of the circuit to
another end. The bulb
will not light because
the flow of electricity
in the circuit is cut.
14. ALWAYS REMEMBER!
There are two conditions that must
be met for the electricity to flow.
1.First, there must be a source of
electricity, and
2.Second there must be a complete
path for the electricity to flow.

Rubrics for Group Activity
19. ALWAYS REMEMBER!
That in a closed circuit, the
path of electricity flows from
the power source to the light
bulb is complete, allowing the
bulb to light up.
20. ALWAYS REMEMBER!
While in an open circuit
where the switch is open, the
path for electricity is
interrupted, preventing the
bulb from glowing as the circuit
is incomplete.
21. WE CAN INFER THAT…..
There are two conditions that must
be met for the electricity to flow.
1. First, there must be a source of
electricity, and
2. Second there must be a
complete path for the electricity to
flow.
24. EVALUATION
____ 1. A circuit where electricity cannot flow
due to a break in the path.
____ 2. There is a complete path of electricity.
____ 3. A circuit where electricity flows
freely.
____ 4. A busted bulb creates a gap in the
flow of electricity. The circuit is _____.
____ 5. Mother checked the bulb lights in
preparation for the coming Christmas season.
When she plugged it on, it does not light up?
What circuit is it?
25. Each group will bring the following for our
activity tomorrow:
-two pieces 1.5 V AA Battery
-one small bulb w/ receptacle
-two 20 cm copper wire
-switch
