5. Motivation
Short discussion of what learners know about electricity.
Ask the learners if they ever wondered where the electricity in
their power outlet comes from.
 How is electricity generated?
 What is the main source of electricity in the Philippines?
 Why are we asked to always conserve electricity?
 Will electricity run out or is it from a perpetual source?
 Ask learners to name different sources of energy and list
them on the board.
Add on the list sources that are not mentioned by the learners.

students are expected to:
1. Describe how energy is harnessed from different sources.
22min.
7. Discussion
Present a diagram showing the different sources of energy in the
Philippines and the percentages of each source. This is to give the
learners an overview of the energy situation in our country. Allow
the learners to compare the main source of energy from the
different regions of the Philippines.

- What are the advantages and disadvantages of using
geothermal energy? You may answer in terms of efficiency of use,
availability, hazards, environmental effect, price, etc.
Hydroelectric
- How is hydroelectric energy harnessed?
- What are the advantages and disadvantages of using
hydroelectric energy? You may answer in terms of efficiency of
use, availability, hazards, environmental effect, price, etc.

IV.
Activity
Group discussion and creation of checklists on how to conserve
electricity.
Divide the class into three groups. Ask them to come up with
concrete steps that they can take in order to help conserve
electricity on a daily basis. On a manila paper, have the learners
create a checklist of things that they will do to conserve
electricity. Provide different settings such as what to do in school,
at home, in the car, etc.
Have the groups post the lists around the classroom for the class
to read.

Generalization
Energy from bond breaking and formation in fuels is converted to
heat energy. This step is not necessary if power generation that
does not require burning of fuels. E.g. Geothermal and hydro
thermal plants. Heat energy is used to convert water to steam
which has kinetic energy. Steam’s kinetic energy becomes
mechanical energy that makes turbines turn. Mechanical energy
from the turbines create electricity via electromagnetism
Energy can be harnessed from fossil fuel, batteries, geothermal,
hydroelectric, wind power, solar cells, biomass.
