Topic 4: Body Image
 A person’s appearance is determined by heredity, environment, and health habits.
 The media portrays beauty as a narrow and limited idea but beautiful people come in all shapes,
sizes, colors, and abilities
 Physical appearance is only one factor that attracts one person to another.

I. ELICT
Before starting our lesson, we will have a short activity, I know you are
already familiar with the GO, GROW and GLOW classification of foods. I
will be showing pictures of different types of foods, what you will do is
identify if it is Go, Grow or Glow. Ready?
Ma’am Go

Ma’am Go
Ma’am Grow
Ma’am Glow
Yes ma’am
Yes ma’am
Do you eat the foods I have shown?
Are all the foods I have shown important for you to eat to have a healthy
body?
Because our body needs different types of
nutrients or compounds for us to grow
healthy and avoid being sickly
Ma’am biomolecules
Why?
What do you call the compounds that are essential to your life?
II. ENGAGE
Now I will show you a video clip about biomolecules, I want you to take
down notes and practice your listening skills. After watching the video
answer the following questions
1. What are the different types of biomolecules?
2. What is a monomer?
3. What are examples of foods rich in carbohydrates?
4. What are examples of lipids?
5. What are the major elements in the biomolecules?
III. EXPLORE
For you to be able to differentiate the different biomolecules let’s do the

IV. EXPLAIN
Based from your activities how will you define biomolecules?
Ma’am biomolecules are most essential
organic molecules, which are involved in
the maintenance and metabolic processes
of living organisms.
Ma’am biomolecules are classified into
four carbohydrates, lipids, proteins and
nucleic acid. Each of them has their own
function
The students will explain their activity
How will you classify them?
V. ELABORATE
Biomolecules are important for the functioning of living
organisms. Several macromolecules (protein,
carbohydrates, nucleic acids, and enzymes) and small
molecules (amino acids, vitamins, fatty acids,
neurotransmitters, and hormones) fall under the category
of biomolecules. These molecules perform or trigger
important biochemical reactions in living organisms.
let us explore the four major types of biomolecules under
Macro molecules: carbohydrates, lipids, nucleic acids, and
proteins.
Biomolecules are the most essential organic
molecules, which are involved in the maintenance and
metabolic processes of living organisms. These non-living
molecules are the actual foot-soldiers of the battle of
sustenance of life. They range from small molecules such
as primary and secondary metabolites and hormones to
large macromolecules like proteins, nucleic acids,
carbohydrates, lipids etc. All living organisms require
several compounds to continue to live. All of these
biomolecules are organic, which means that they contain
carbon. Carbon has four valence electrons, which means
this element forms strong covalent bonds with many
other elements.

Biomolecules are Organic Molecule
• Molecules containing Carbon, Hydrogen, Nitrogen, and
Oxygen.
• All are polymers
• All are organic (C) compounds
• They make up living organisms
Functions:
1. Carbohydrates – Energy source for cell and provides
structural support for plant cells.
2. Proteins – Speeds up chemical reactions, transport
molecules and build and repair cells. Enzymes, structure,
recognition, transport pigments, signals, and movement
3. Lipids – Cell membrane structure for long term energy
storage, signals
cellular metabolism (Vitamin K) and cell membrane
structure.
4. Nucleic Acids – Hereditary and protein information
(genetic blueprint),
energy, signals.
Do you think these biomolecules are important in your
development as a teenager?
Correct these molecules really does affect many processes
in your body, you said earlier that it affects our
metabolism. What exactly is metabolism?
Proteins are very important in our body it affects your
hormones, which I know you are already familiar with,
since we already discussed it last quarter.

Correct the media tells us that we need to be sexy, light
skinned, tall etc. to be called beautiful and also for us to be
liked by others. That’s why others go to extremes like
changing how they look just to fit society’s standard of
beauty. But always remember class beauty is just skin
deep,
What is essential is invisible to the naked eye. Yes, it is
Yes ma’am, because these molecules have
different functions in our body. They also
affect our body processes which includes
our body metabolism, production of
hormones and many more
Ma’am it is the chemical reactions in the
body's cells that change food into energy.
Our bodies need this energy to do
everything from moving to thinking to
growing. Specific proteins in the body
control the chemical reactions
of metabolism.
Eat foods rich in nutrients and exercise
Ma’am to be called beautiful or
handsome we have to be light skinned,
tall, fit, sexy and look like the beautiful
people we see on television

important that we watch what we eat, but it is also
important to have a good heart because in the end beauty
will fade but character will stay.

VII. EXTEND
To further deepen your understanding about biomolecules in our lives, let
us try to do this activity in the “Deepen” part of your module
Activity 1: “Nutrition Pahalagaan, Mabuting Kalusugan Ating
Bantayan ”
Goal: To create a tri-fold brochure that would help spread
awareness on the relevance of proper nutrition to
encourage high school students to monitor their eating
habits.
Role: Spoke person of the “Nutrition Center of the
Philippines (NCP)” a nonprofit organization established in
1974 to help address malnutrition in the Philippines. They
work with both government and non-government sectors
to achieve Nutrition Security for all Filipinos, especially for
those who are disadvantaged.
Audience: The target Audience are Junior High School
Students.
Situation: First, You need to discuss through the use and
words and pictures, the relevance of proper nutrition on
our health. Second, suggest also food that are rich in
carbohydrates, proteins, and fats that are healthy to
consume. Third, discuss the importance of good eating
habits in boosting our immune system to shield ourselves
from pathogens and viruses. Lastly, add at least three of
your own tips on how to stay healthy specially in this time
of pandemic.
Product: Nutri Tri-fold Brochure
Students will answer the questions
