Module 4: Current and Voltage for Science 8 prepared powerpoint presentation for formal demonstration.

1. MODULE 4:
ELECTRICITY
Current and Voltage
Prepared by: Rea Christymae A. Duran

2. OBJECTIVES:
At the end of the session, the
students are expected to:
define electric current and
voltage; and
determine the unit, symbol,
physicist involved, and device
used of electric current and
voltage.

3. A. Recall:
"Jeopardy" is a classic game show strategy. The questions are
categorized into two (2) and you have to choose which category
to answer. Under each category are sub-categories which
corresponds points respectively.

4. Follow the Law!
MOVE IT!
HEAT IT!
Stop!
Bounce Back…
Do the work.
How cold is it?
Proceed

5. Follow the Law – Stop!
(for 5 points)
State the LAW OF INERTIA
A body in motion, will stay in motion.
A body at rest will remain at rest,
unless acted upon by
external/unbalanced force.

6. Follow the Law – Bounce back!
(for 3 points)
Which of the following laws of motion does the statement follow?
A basketball player dribbling the ball on
the floor.
LAW OF INTERACTION
(ACTION-REACTION)
HOME

7. MOVE IT! HEAT IT!– How cold is it?
(for 2 points)
What is the freezing point of
a water?
0°C
HOME

8. MOVE IT! HEAT IT!– Do the Work?
(for 3 points)
Tell whether WORK IS DONE or NONE.
 Carrying the books from the tale to
the cabinet.
WORK IS DONE

9. B. Motivation:

10. Battery

11. Electric Bulb/Bulb

12. Electrical Wire/Electrical Cord/
Electrical Cable

13. Switch

15. Unlocking of Terms.
 Electric current (I) - measure of the number of
electrical charges passing through a cross-
section of a conductor in a given time.
 Ampere (A) – unit of current; named after
French Physicist, Andre-Marie Ampere (made
important contributions to the theory of
electricity and magnetism.
 Ammeter – device used to measure electric
current.

16.  Voltage (V) - is the difference in charge
between two points and the force of
electric current.
 Volts (V) – unit of voltage; named after
the Italian Physicist, Alessandro Volta
(who invented the voltaic pile, the
forerunner of what we now call the dry
cell.)
 Voltmeter – device used to measure
voltage.

17. ACTIVITY PROPER:

18. • In this activity, you must proceed to
your group and form a circle within.
Wait for the teacher to say, GO!
• Each member of the group must take
full responsibility with respect to their
assumed roles.

19. Mechanics:
1. Each group will be provided strips of
papers with the word/words written in it
in a jumbled manner (i.e. CURRENT –
TNERRUC) and other materials needed.
2. The jumbled letters must be unlocked by
writing your answer beside the jumbled
letters; once done, look for the definition
of the unlocked terms.
3. However, the group has to divide the
manila paper into two compartments.

22. • Interview an electrician from your
barangay or purok or anyone you know
who has knowledge about electricity
regarding:
• How does the electricity work?
• Is current and voltage responsible of the
so called, Black out or Brown out?
• Record your interview for everyone to
hear and learn new knowledge.
