ELICIT
A. Reviewing previous lesson
or presenting the new
lesson
These steps should be done across the week. Spread out the activities appropriately so that
students will learn well. Always be guided by demonstration of learning by the students which
you can infer from formative assessment activities. Sustain learning systematically by providing
students with multiple ways to learn new things, practice their leaning, question their learning
processes, and draw conclusions about what they learned in connection to their experiences
and previous knowledge. Indicate the time allotment for each step.
INDICATOR 2.Used a range of teaching strategies that enhance learner
achievement in literacy and numeracy skills.
INDICATOR 9. Used strategies for providing timely, accurate and
constructive feedback to improve learner performance
The teacher will review the previous lesson on WORK and POWER by asking
students questions and do the following:
1. What is the formula for WORK? Its Unit is?
2. What is the formula for POWER? Its Unit is?
3. Compute for Work and Power of the given problem.

ENGAGE
B.
Establishing a purpose for the
lesson
INDICATOR 1. Applied knowledge of content within and across curriculum
teaching areas.
INDICATOR 2.Used a range of teaching strategies that enhance learner
achievement in literacy and numeracy skills.
INDICATOR 4. Displayed proficient use of Mother Tongue, Filipino and
English to facilitate teaching and learning.
INDICATOR 7. Established a learner-centered culture by using teaching
strategies that respond to their linguistic, cultural, socio-economic and
religious backgrounds.
Grade 9 MELC-Explain how thermal energy can be used to do work (S9FEIVf-5); Grade 10 MELC-differentiate between electrical power and energy
(S10FE-IIe-21)
After which, the teacher will engage and motivate the class by asking the
question:
What comes into your mind whenever you hear the word ENERGY?
Then teacher will present the Unlocking of Difficulties to provide students
with the important Terms of lesson.
1. Energy – the capacity to do work
2. Potential Energy – energy of an object at rest. It is also called stored
energy. It has potential to do work once release.
3. Kinetic Energy – energy possesses by a moving object. It comes from
the Greek word “kinetikos” which means moving. Kinetic energy
quantifies the amount of work the object can do because of its
motion.
4. Work – is a way of transferring energy. Once work is done on the
body it gains energy. But if a body does work it losses energy.
5. Joule – unit of work and energy. It is also equivalent to 1 Nm and 1
kg m2 /s2
C.
Presenting examples/instances of
the new lesson
Then, the teacher will provide examples/instances of the new the lesson by
showing learners different examples and sources of energy.

With the formula given by the Teacher, Students will answer guide questions
in the Exploration 2 activity and compute for change in Potential Energy with
the given formula.
The work done on the object to raise it at that height is given by the
equation,
then, the change in the object’s gravitational potential energy is:
Given the two equations, we can derive the formula for the relationship of
work and energy given below.
