Detailed lesson plan in biology
1. A Detailed Lesson Plan in Biological Sciences
Prepared by: Jonessa U. Gurrea
I. Objectives:
A. At the end of one-hour and thirty minutes discussion 90% of the students will be
able to have 95% mastery of the light and dark reaction in the process called
photosynthesis.
B. At the end of the discussion the students will be able to differentiate and define
the different steps for both light dependent and independent reactions.
II. Subject Matter:
BIO11- Biological Sciences: Photosynthetic Light & Dark Reaction
III. Materials:
Colored papers- for star shaped cut-outs.
Illustration board- used for showing the different steps of light & reaction mechanism in a
closer look.
Projector Screen & Projector- for multimedia presentation.
III. Procedure:
A. Learning Activities
Teacher’s Activities Student’s Activities
“Good afternoon class.”
“How are you today? I presume that you
are prepared to listen in our lesson but
before that please lead us the prayer
Ricson.”
“Thank you Ricson”
(Teacher checks the attendance)
“I guess everyone’s present. So class,
fasten your seatbelts as we travel to a plant
food production journey. Be cautious along
the way, there might be questions that
needs answers. You’ll surely wouldn’t like to
miss the points it will give.
“Have you ever ask yourselves class why
we buy foods for our consumption? Why
can’t our system produce our own food
“Good afternoon Ma’am”.
(Ricson leads the opening prayer.)
“You’re welcome ma’am”.
“Wow! That sounds interesting Ma’am!”
One student raise his hand.
2. supply to sustain our daily living?” Just like
the plants, they produce their food. They
even produce/serve as foods for us human
beings. Am I right?”
“Yes Vince, do you have something in
mind?”
“You have a good idea Vince; plants fall
under the category of producers. They have
the ability to produce food on their own in
the process called what…?”
“Yes Ma’am, you are right. Plants are
producers and we animals are the
consumers. It is because we cannot
produce our own food but plants do in a
chemical process called photosynthesis.”
“Photosynthesis Ma’am”
(All students said in unison.)
Teacher’s Activities Student’s Activities
“Everyone will get a pink star for being
participative today, and Vince will received
red star for sharing his thoughts.”
“Yes Carmel?”
“Oh, when you get a red star it means
you’ve garnered 5pts for oral participation
and pink star for 2pts. So next time you
should participate.”
“Let’s proceed”
“Photosynthesis is a process used by plants
to convert light energy, normally from the
Sun, into chemical energy that can be later
released to fuel the organisms' activities. It
has two parts; first the light reaction and
second the dark reaction.”
“Good question Nessa.”
“To answer that take a look at this
illustrations. They’re pretty colorful right?
This is the thylakoid membrane found in the
leaf of a plant. It is in this place that the
light reaction occur.”
(One student raises his hands.)
“What is that pink and red star represent
Ma’am?
“I see, thanks Ma’am”
“Why is it called light reaction Ma’am?”
Asked Nessa.
“Yes, very colorful indeed”
3. “It is called light reaction because this occur
in the presence of the sunlight. Dark
reaction
on the other hand occurs in the absence of
light.”
(The teacher points out the illustrated
board for the students’ reference.)
“Let us go back to the first step of
photosynthesis, the light-dependent
reactions is a process by which plants
capture and store energy from sunlight. In
this process, light energy is converted into
chemical energy, in the form of the energy-
carrying molecules ATP and NADPH. In the
light-independent reactions, the formed
NADPH and ATP drive the reduction of CO
2 to more useful organic compounds, such
as glucose. However, although light-
independent reactions are, by convention,
also called dark reactions, they are not
independent of the need of light, for they
are driven by ATP and NADPH, products of
light. They are often called the Calvin Cycle
or C3 Cycle.
“For a better picture, let’s watch this video”
“Okay now I want you to write something
about the video you just watched in a clean
sheet of paper.”
“If you’re done please submit it here. Since
we don’t have enough time to continue our
discussions today please read in advance
our next topic which is the dark reaction.
Please familiarize its steps.”
“Vince kindly lead us the closing prayer.”
“Thank you very much Vince, Class
remember to keep your earned stars
because I’ll be collecting that at the end of
the semester, is that clear?”
“You’re welcome, Good Bye class, its nice
meeting you today.”
(The students are focused on the illustrated
materials.)
(The students are focused on video
presentation.)
“Yes Ma’am”.
“Yea Ma’am! Thank you.”
“Good Bye Ms. Jonessa.”
4. IV. Evaluation
The teacher will let the students watch a video of the detailed steps of the Light
Dependent reaction and write a reflection about it.
V. Assignment
In continuation of the first discussion, the teacher tasked the class to read in
advance what Dark Reaction is about, its steps, and how it is different from the light
reaction.
