This document is a daily lesson log for a science teacher teaching lessons on the respiratory and circulatory systems. It outlines the objectives, content, learning resources and procedures for lessons taught over multiple days. The objectives are for students to understand how the respiratory and circulatory systems work together and ways to prevent diseases affecting these systems. Content covered includes the key parts and functions of the respiratory and circulatory organs, how gas exchange occurs, and common diseases. Learning activities include labeling diagrams, demonstrations, videos and crafting models to reinforce understanding of the complex systems.

IV. PROCEDURES
A. Reviewing previous lessons or
presenting the new lesson
Perform the Pre-test in
L.M. p. 73-74 to assess
prior knowledge.
What are the parts of
plants and organelles
essential to food
making process?
What processes are
involved in food making?
Write the word equation of
photosynthesis.
Cite evidence that shows
photosynthetic process.
1. What are the raw
materials and product
of photosynthesis?
2. What organelles play
an important role in
photosynthesis?
3. How do you describe
photosynthesis using
the word equation?
B. Establishing a purpose for the
lesson
Why do you think plants
are called great food
providers?
Well, the sun comes
streaming out of the
sky making
everything grow and
keeping us alive and
our main connection
to the sun are the
green leaves, only
Think-Pair-Share:
Do plants really capable
of making foods?
Unlocking of Word
Difficulty:
Enzymes, Chloroplast,
Humidity, Temperature
This will lead to factors
affecting photosynthesis.
English Learners:
Students will use word
triangles to review the
molecules involved in
the process of
photosynthesis. (To
complete a word
triangle, students draw

with sunshine energy.

Rock and Roll of

What is implied in the
song?
one triangle for each
word and divide the
triangle into three
bands horizontally. The
new vocabulary is
placed in the middle
band, the definition of
the word is written on
the bottom band and a
diagram of the word is
written in the top band).
Art Education:
Students will draw a
leaf diagram and use
this to illustrate what
goes in (reactants),
and what comes out
(products) of
photosynthesis.
GATE:
Students will
sequence the process
of photosynthesis and
identify specific
reactions involved,
using a “flow map” (or
C. Presenting examples/ instances of
the new lesson
Show pictures of
different food products
locally made from
Khong Guan since
students are very
familiar with it.
How do you think these
products are made
available for us?
(Elicit answer that will
lead to the concept of
how are these foods
manufactured.)
Picture Analysis.
Teacher asks
students what
materials are involved
in the process of
photosynthesis.
Students think about
the question for one
minute, then turn to a
shoulder partner and
discuss their thoughts
to the question.
Worked Example with
Answer Analysis:
Devi covered a part of a
leaf with a black piece of
paper and left the leaf in
bright sunlight for several
days.
She then carried out the
iodine test for starch.
What do you think
happens to the leaf?
(The part of the leaf
covered by the black
paper cannot
photosynthesize and
would be unable to
manufacture sugar and
starch. Therefore, when
tested with iodine
solution, the area would
remain pale. The rest of
the leaf would be positive
to the iodine test and
produce a dark blue
stain.)
There’s an old saying that
goes,” Para maganda ang
tubo ng mga halaman
kausapin mo ito palagi.”
Is there any truth to this
saying?
What scientific
explanation lies behind
the saying?

are the Structures
Involved In the Food
Making Process in
Plants? pp. 75-77
Perform Activity:

other suitable maps for
sequencing events).
E. Discussing new concepts and
practicing new skills #2
F. Developing mastery
(Leads to Formative Assessment )
Discuss the findings in
each Learning Station.
1.What are the parts of
chloroplast and internal
structure of leaf that are
involved in the process
of photosynthesis?
2. What are the raw
materials and products
of photosynthesis?
3. How would you
describe the entire
process of food making?
Discuss the answer to
guide questions in the
activity.
1.What reactants or
materials are required
for the process of
photosynthesis?
2. What products are
formed in the
process?
3. What happens to
the light energy in the
thylakoid membrane
of the chloroplasts?
4..How does the
energy from sunlight
used to build sugars?
Process the Activity:
Observations and data
gathered would lead to
the discussion of the
different evidences in
photosynthetic process.
Discuss the answer to the
Guide Questions.
Key Concepts would be
Enzymes, Temperature,
Carbon Dioxide, and Light
Computer Aided
Activity:
Students make a
multimedia
presentation of
photosynthetic
process.
G. Finding practical applications of
concepts and skills in daily living
If one of the organelles
or parts of a leaf will not
function, is there a
chance for
photosynthesis to take
place? Why or Why not?
Students should
create an analogy for
the process of
photosynthesis and
compare each part of
the process with some
Imagine that you are a
farmer, what ways would
you suggest to yield better
crops?
Supposed there are 2 jars
with burning candle and
one has potted plant
inside. Both jars are
placed near a window in
strong sunlight.

27. other process in
everyday life. (Ex. The
process of
photosynthesis is like
baking bread).
Question:
Why does the burning
candle in jar without
potted plant stop burning
before the candle with
potted plant?
H. Making generalizations and
abstractions about the lesson
1. What are the
organelles essential to
the process of
photosynthesis?
2. How are these
organelles work together
in the entire process of
food making?
1. The overall process
of photosynthesis
uses water and
carbon dioxide to
produce sugars that
store chemical
energy.
2. Sunlight is
absorbed using plant
pigments called
chlorophyll, and the
process of
photosynthesis takes
place within
organelles called
chloroplasts.
3. Energy from
sunlight is captured
during the light-
dependent reactions
and is used to build
sugars during the
light–independent
reactions.
What evidences are
shown that photosynthetic
process takes place? What are the factors or
conditions that affect
photosynthesis?
