HAZARD PROHIBITION
A hazard is a potential
source of harm.
It is a symbolic
representation of
information using
visualization techniques.
It is the act or practice of
forbidding something by law

8. ELECTRICA
L SIGN
Are pictures of a symbol intended to alert and instruct
people to avoid potentially hazardous condition.
- Knowing and understanding these symbols will
help you operate your tool better and more safely.

9. Indicates a hazardous
situation which, if not
avoided, will result in
death or serious injury.
Indicates that a person
should observe extra
awareness.
Indicates some
precautionary
measures against
potential hazardous
situation which, if not
avoided, may result to
a minor or moderate
injury.

12. Other Circuit
Components
Shown below are other circuit
components and their corresponding
electrical symbols:
battery closed switch open switch

16. Activity # 3 “Symbol Sort”
Directions: Two Grouped-activity. Each group will pick an envelope, inside the envelope are the
corresponding task the group will perform.

17. When these electrons pass through
a load or a receiver, electrical energy
can change into other forms, such
as light, heat and sound.
A dry cell provides the ‘push’ needed
for electrons to flow in the loop.
These electrons are already present
in the wires.

18. Completing the Circuit
Use the electrical symbols when
drawing the circuits.
1 way to connect them to
get the bulb to light up?
Given a bulb, a wire and a cell,
can you suggest:
1 way to connect them such
that the bulb does not light up?

SAMPLE ANSWER

20. WITH THE HELP OF YOUR TEACHER OR CARER,
TEST WHETHER YOUR SUGGESTIONS AND DRAWINGS WILL
MAKE THE BULB LIGHT USING ACTUAL BATTERIES, A SMALL
LIGHTBULB, AND WIRES.
Completing
the Circuit
EXTENSION ACTIVITY
With the help of your teacher or carer, test
whether your suggestions and diagrams will
make the bulb light using actual batteries, a
small lightbulb and wires.

21. Conductors vs Insulators
These materials allow
charges to flow freely.
These materials resist the
free movement of charges.
Conductors Insulators
silver
spoon
copper wire
rubber
balloon
rubber tire
diamond

22. WITH THE HELP OF YOUR TEACHER OR CARER,
TEST WHETHER YOUR SUGGESTIONS AND
DRAWINGS WILL MAKE THE BULB LIGHT USING
ACTUAL BATTERIES, A SMALL LIGHTBULB, AND
WIRES.
Think
About It!
Can you name other
conducting materials
aside from copper wire
and silver spoon?

23. Electric circuits play a crucial role
in our daily lives.
It allows specific
devices to
produce heat
and sound.
It allows
light bulbs
to light up.
It helps trains
move and makes
travelling to work
or school easier.
It enables the
cooling system of
a refrigerator to
work.
What can electric
circuits do?

24. A complete circuit
features an unbroken
loop where charges
can flow.
It is a complete path
through which electric
current flows.
Some of its
components include
wires, a bulb and a
power source (cell or
battery).
