This document appears to be a presentation on electricity and energy transformation presented by Shiela D. Macatangay to Grade 6 students. It covers key topics like: - The definition of electricity and that it is a secondary energy source obtained from converting primary sources like coal, gas, and oil. - The concept of energy transformation as the process of converting one form of energy to another. - Examples of energy transformation include hydropower plants that convert potential energy of water into mechanical and then electrical energy, and wind turbines that convert kinetic energy of wind into electrical energy. - Safety precautions around electricity use such as avoiding overloading outlets, not handling appliances with wet hands, and letting professionals

7. ‘‘HELPING CHESTER’’

8. Mechanics:
I have here a situation where
you will help Chester what to
do with the given situation.
Are my instruction clear?

9. Chester, wants to watch the latest single of
his favorite k-pop group which is twice. What
are you going to do to help Chester watch
his favorite k-pop group?

10. Chester is holding an ice cream, what are you
going to do to help Chester not to melt the ice
cream?

11. Chester, is tired and he want to sleep but
it is too hot, what he is going to do make
him feel relax?

12. Electricity
and
Transformation

13. Electricity
Electricity is the flow
of electrical power or charge. It
is a secondary energy source
which means that we get it from
the conversion of other sources
of energy, like coal, natural gas,
oil, nuclear power and other
natural sources, which are
called primary sources.

14. Energy Transformation
is a process of converting
one form of energy to
another.

15. Energy
energy cannot be created
nor destroyed.

16. Most power plants are fueled by coal, oil or gas.
These fuels are fed into burners and the heat boils
water into steam but the problem with these power
plant is the pollution that they release into the
atmosphere.
Hydropower plant

17. ILIJAN POWERPLANT

18. Hydropower plant
Hydropower plants convert potential energy into
mechanical energy through water turbines, which
then generate electricity.
Hydropower plants, dams are built to hold the
water in artificial lakes. Water is then released
gradually to fall down, like an artificial waterfall

19. Hydropower plant

20. Wind turbine
a turbine that converts the
mechanical energy of its rotation
into electrical energy. The faster
the turbine turns, the more
electricity is produced.

21. Wind turbine

22. How do the appliances work?

23. Converting Electricity to other
Useful Forms
electricity gets converted to other
forms of energy that we need or
wants. Many appliances have
motors-converter into kinetic
energy.

25. What are the appliances in your home that has
cooling elements?

26. What are the appliances in your home that has
heating elements?

27. Some of our appliances provide
heating elements which high
resistance segment of metal that
convert electricity into thermal
energy, while cooling elements
they have cooling coils inside.
They absorb heat from the air,
then bring the heat out.

28. Cooling coils Heating
elements

29. what are the devices that convert electricity into
light?

30. what are the devices that convert electricity into
sound?

31. Electricity makes our lives
comfortable, but it can be
destructive when not used
carefully. Many people have lost
lives and homes due to accidents
like short circuits and overloading.

32. Safety Precautions in Using Electricity
 Avoid octopus connection. Do not use adapters that
allow to many appliances to be plugged in.
 Do not placed appliances close to water sources.
Do not touch electrical appliances with wet hands

33.  Do not try to repair appliances yourself. Let us
trusted repair men and technicians to do them for
you.
 Make sure that appliances you use are rated at
220 volts. If you want to use appliances rated at
110 volts, use the transformers with them.

34. We use electricity in our
daily life. At present, many
places in our country
experience brownout due to
shortage of electric supply.

35. Efficient Use of Electricity
 Turn off lights and appliances when they are not in
use
 When ironing the last pieces of clothes, turn the
setting to low or even turn it off.

36.  When using the washing machine, put as many
clothes as possible in one load. It saves a lot of
clothes in just one load
 Monitor your electricity consumption. Inform your
parents if your bill suddenly goes up.

37. Remember:
We should always put
those things into practice
in order to conserve
energy.

38. It is the flow of electrical power

40. What is energy?
energy cannot be
created nor destroyed.

41. What are the appliances in your home that
have motors?
electric fan
washing machine
blender.

42. appliances in your home that has
cooling and heating elements?
Refrigerator
Air conditioner
Rice cooker
Oven toaster

43. What are some safety precautionary in using
electricity?
Avoid octopus connection. Do not use adapters that allow to many
appliances to be plugged in.
Do not placed appliances close to water sources. Do not touch
electrical appliances with wet hands
Do not try to repair appliances yourself. Let us trusted repair men
and technicians to do them for you.
Make sure that appliances you use are rated at 220 volts. If you
want to use appliances rated at 110 volts, use the transformers
with them

44. What are the things we should practice to help us
use electricity efficiently?
Turn off lights and appliances when they are not in use.
When ironing the last pieces of clothes, turn the setting to low or
even turn it off.
When using the washing machine, put as many clothes as
possible in one load. It saves a lot of clothes in just one load.
Monitor your electricity consumption. Inform your parents if your
bill suddenly goes up.

45. Direction: On a sheet of paper write efficient
if the statement is about to conserve energy,
and safety if the statement is about
precautions in using electricity.
1.Avoid octopus connection.
2. When food is on the stove is already
boiling, switch to low setting or turn it off.

46. 3.When buying appliances check
for the energy saving features.
4. Check all the wirings on your
appliances.
5. Do not place appliances close to
water sources.
