1. Identify the major classes of Biomolecules;
2. Classify the different type of carbohydrates and lipids; and
3. Give the importance of biomolecules in our daily lives

PROCEDURES:
A. Learning Activities
Teacher’s Activity
“Good Morning Class…”
“Let Us Pray First…”
(Checking of Attendance)
“ Please keep all unnecessary things on your
table and we’ll start with the class
(Review)
Student’s Activity
“Good Morning Ma’am”
(One student will lead the Prayer)
(Students will tell who’s absent for the day)
( Students will keep their things that nothing
to do with the lesson)
(Students will tell about what they recall
about the lesson last meeting).
Last meeting, we learn about biomolecules.
So as sort of review, who can tell me what is
biomolecules?
Biomolecules is any molecule that is
produced by living organism. Including
large macromolecules such as proteins,
polysaccharides, lipids, and nucleic acids.
Very Good!
Now, we’re going to have a game. I will
divide the class into 3 groups and each group
will select 1 representatives to tell their
answer . This game will be related to your
previous lesson and also to your future
lesson.
Are you familiar with 4 Pics. 1 Word?
Yes, Ma’am.
Okay. From this game you are going to
guess 1 word for the 4 picture that I show.
I’ll give you a little bit of time to discuss
your group as one of your answers and the
representative will say the answer
immediately, the first 1 who got the answer
will get 10 points and will be rewarded.
Is that clear class?
Yes, Ma’am.
( After the game)
From your activity game, we have four main
classes of biomolecules there, so what are
those?
Very Good
So, is there any question regarding our
previous lesson?
Ma’am, we have the carbohydrates, lipids,
proteins and nucleic acids.
None, Ma’am.
B. Developmental Activities.
Teacher’s Activity
A. Motivation :
Student’s Activity
( Show a picture of a marathon runner)
Look at the picture. What do you see?
Ma’am, a marathon runner.
So, In your own idea class. What should the
runner eat the day before the race?
Ma’am, those heavy foods like rice, corn, egg
and milk.
So, what classes of biomolecules are those?
Ma’am, those are carbohydrates and lipids.
So, why should the runner eat those foods
rich in carbohydrates and lipids?
Ma’am, because both carbohydrates and lipids
are used as energy sources for cell
metabolism.
Okay class. Now that you’re familiar with
Carbohydrates and lipids. Let’s move on to
our next topic.
B. Presentation :
( Show a short video clips about the 2 major
group of Biomolecules )
To enhance your understanding on the
two major groups of biomolecules which is
the carbohydrates, lipids. I have here a short
video clip. So, please as you watch the
video take down notes and watch
attentively.
Is that clear class?
Yes, Ma’am
C. Discussion:
1. Concept Formation:
Based on the video that I’ve show you.
What are the 3 classification of carbohydrates?
Ma’am. monosaccharides, disaccharides, and
polysaccharides
So, what are the two common
monosaccharides?
Ma’am. Glucose and Fructose.
How about the three disaccharides?
Ma’am. Sucrose, Lactose and Maltose
Okay how about the three common
polysaccharides?
Ma’am. Starch, glycogen and cellulose.
So, what are two classifications of lipids?
Ma’am. We have the oil and fats.
Very Good!
D. Generalization:
Okay Class, let’s have a recap on what we have Ma’am Biomolecules is any molecule that
discussed today. So, what are Biomolecules ?
produced by living organism.
What are the 4 major classes of Biomolecules?
Ma’am we have Proteins, Lipids,
Carbohydrates and Nucleic acids.
Correct!
What is the simplest biomolecules?
Ma’am Carbohydrates
So, what are examples of carbohydrates?
Ma’am Sugar
Another?
Ma’am Starch
Ma’am Cellulose and Glucose
What else?
Very Good!
It is a high energy molecule that plants and
animals use to store energy in reserves for
longer periods?
Ma’am Lipids
You’re Right!
How about examples of lipids? Can you give?
Ma’am Oils and Fats
Yes that’s Good!
Anything else?
Ma’am Phospholipids and Steroids.
Very Good!
E. Application/Appreciation:
In your own idea. Can we consider fats good or It depends. If we eat in moderation, fats are
bad? Why?
good sources of body fuel. They are considered
good emergency food and are efficient energy
storage system. However, an excess quantity of
fats is not good for the heart. Because they tend
to clog arteries and overwork the heart.
Very Good!
IV.
EVALUATION:
Direction: Analyze each question carefully then choose the letter of the correct answer.
Encircle the letter of your answer. (2 points each)
