I. OBJECTIVES
Objectives must be met over the week and connected to the curriculum standards. To meet the objectives necessary procedures must be followed and if needed, additional lessons, exercises, and
remedial activities must be done for developing content knowledge and competencies. These are assessed using Formative Assessment strategies. Valuing objectives support the learning of content
and competencies and enable children to find significance and joy in learning the lessons. Weekly objectives shall be derived from the curriculum guides.

Stellar Formation and Evolution
Formation of Elements During
Stellar Formation and Evolution
The Synthesis of New Elements The Synthesis of New Elements
III. LEARNING RESOURCES
Let the materials to be used in different days. Varied sources of materials sustain children’s interest in the lesson and in learning. Ensure that there is a mix of concrete and manipulative materials as
well as paper-based materials. Hands-on learning promotes concept development.

B. Other Learning Resources
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 learning, question their learning processes, and
2. IV. PROCEDURES draw conclusions about what they learned in relation to their life experiences and previous knowledge. Indicate the time allotment for each step.
A. Reviewing previous lesson or
presenting the new lesson
The teacher will give the overview of
the objectives and key terms for the
quarter.
1. Give a big picture of Chemistry by
describing it as “the study of stuff.”
The teacher will recall the Big Bang
nucleosynthesis and the formation of
lighter
elements.
The teacher will recall the evidences
for and describe the formation of
heavier elements during star
formation and evolution
The teacher will introduce the
following list of important terms that
learners will encounter.
B. Establishing a purpose for the lesson
The teacher will briefly define
cosmology as the study of how the
universe began, how it continues to
exist, and how it will end.
(Offer examples of cosmologies from
different religions and cultures based
on their beliefs)
Guide Question?
1. Do you think there is proof that any
of these stories or cosmologies are
true?
The students will try to refresh your
mind by supplying the number of
protons and neutrons of each
element.
The Cosmic Connection
The teacher will use the Think, Pair,
Share protocol and ask learners to
reflect and share their thoughts on
the selection.
Stellar Word Puzzle!
The learners will encircle and write
down the words which are related to
star and element formation.
3. C. Presenting examples/instances of the
new lesson
The learners will give important
clues in understanding the
fundamental building blocks of the
universe and how life on earth is
connected to stars.
In the Beginning: The Nebulae!
Guide Questions?
Question 1: Where do you think stars
come from?
The learners will share their insights.
Growing Older, Growing Bigger:
The Red Giant Star!
Guide Questions:
Why do you think red giant stars are
called red giants?
The students will examine the
diagram from your left. It illustrates
an atom’s subatomic particles
namely:
a. protons+
b. neutrons 0
c. electrons _
Activity I.I Making Your Own
Periodic Table
The learners will make their own
periodic table using the hypothetical
elements that are given in the clues.
a. P and Pr both have one electron
each. Pr has a bigger atomic size.
b. Od, Ri, and E are in the same series
as P, C, and I. In terms of atomic
size, P is the biggest while C is the
smallest. E is a metal while I is a
non-metal. Od is smaller than Ri in
atomic size.
D. Discussing new concepts and
practicing new skills # 1
The learners will explore the vast
universe with the countless twinkling
diamonds in the sky.
1.Stars’ Starting Point of Life: The
Protostar!
Guide Questions:
1. What is the core of it all?
The Death of a Star: Depletion of
Energy!
Guide Question:
1. Do you think stars explode when
they die?
The students will determine their
quantity in a certain element
How about isotope 13 Carbon?
protons ____ atomic no.___
neutrons ___ atomic mass__
The learners will write the balanced
nuclear reaction of the following
elements under alpha, beta and
gamma decay.
E. Developing mastery/ Finding practical
applications of concepts and skills in
daily living / Making generalizations
and abstractions about the lesson
Activity 1- “Forget Me Not”
The learners will identify the
following and tell something about
each of them.
Activity 1- “Star in the Making
The learners will demonstrate what
they have learned on the formation
of stars by doing any of the
suggested star projects.
Comic Story- create a one-page comic
star’s life cycle story (cartoons or
cut-outs)
Activity 1-Transformation-
Radiation in One!
The learners will choose the letter of
the symbol that represents the type
of nuclear radiation
Activity 1.1
The learners will write the nuclear
reactions involved in the synthesis of
each of the following new elements:
a. Curium (Z = 96) was formed by
reacting Pu – 239 with alpha
particles 42He. It has a half-life of
162 days.
b. Mendelevium (Z = 101) was formed
by reacting En-253 with alpha
particles.
4. Rubrics
F. Evaluating learning
Activity 2 – “Twinkle, Twinkle Little
Big Star, How I Wander as You Are!”
The learners will relate the evolution
of a star to the life cycle of a person.
The students will identify the
temperature of each color?
Use this temperature list: 3000 °C,
4500 °C, 6000 °C, 10 000 °C, 40 000
°C
Wrap up!
The learners will answer the
following as you look back at the
things we have talked about today.
1. What is the missing link that led to
the completion of the known
“almost perfect” periodic table of
elements? How did it lead to the
discovery of synthetic elements?
2. How do scientists forge the
synthesis of elements?
3. What happens during the
synthesis of new elements?
The students will create an inventory
list of universe’s fragments into a
systematic compilation that includes
the new synthetic elements
G. Additional activities for application or
remediation
