A. Before the Lesson
ELICIT
Preliminary Activities:


Prayer
Checking of Attendance
Review:
 The teacher will ask the students about previous lesson on Circulatory
System
Drill: THE GAME OF CARBOHYDRATES
1. The teacher will ask a volunteer from the class.
2. The student – volunteer will stand in front of the class.
3. The mechanics of the game are:
 A word is placed on top of the guesser's forehead
 The word-guesser must ask a series of deductive
questions that becomes more specific over time
 The whole class will be the other player that must only
reply with “yes”, “no”, or “maybe/possibly”.
4. The goal of the game is to correctly guess the word in under two
minutes.

Essential Questions:
1. What are the different classifications of carbohydrates?
2. How can we identify the simple and complex carbohydrates?
*to answer these questions, let’s have this activity first.
B. Lesson Proper
EXPLORE
 The teacher will present an activity. This Game is called
CARBOHYDRATE FACTORY. The learners will have to
guess which classification of carbohydrates does the printed
pictures pasted on the board belong.
1. What is carbohydrate?
2. What are its classifications?
EXPLAIN
3. How can you identify simple from complex carbohydrates?
4. How do carbohydrates break down?
5. Why does carbohydrates important in the body?
C. After the Lesson
What are carbohydrates?
 An organic compound and is the main energy source of the body.
They are large macromolecules consisting of carbon (C),
hydrogen (H) and oxygen (O) and has a general formula of
C(H2O). They are taken in the form of all foods made up of grain
flour, cereals, pasta, potatoes and other vegetables, and also in the
form of sugars contained in fruits, syrups, honey and candy, as
well as in the pure crystalline form of our familiar table "sugar".
ELABORATE
What are its classifications?
 Carbohydrates are classified into monosaccharides,
disaccharides, and polysaccharides. Where monosaccharides are
the simplest form of carbohydrates, also called simple sugars.
Disaccharides are two monosaccharide units linked together
through a condensation reaction. Polysaccharides are made up of
multiple monosaccharide units
How can we identify simple and complex carbohydrates?
 Simple carbohydrates refer to the carbohydrates that contain
single monosaccharide units while Complex carbohydrates refer
to carbohydrates that is made up of hundreds or thousands of
monosaccharide units. Simple carbohydrates are easy to digest
and complex carbohydrates takes time to digest. Simple
carbohydrates include monosaccharides and disaccharides.
Complex carbohydrates include polysaccharides such as starch.
Simple carbohydrates contain sweetness and quickly raise blood
glucose levels while complex carbohydrates are less sweet and
slowly raise blood glucose levels.
How do carbohydrates break down?
 Your body breaks down carbohydrates into glucose. Glucose, or
blood sugar, is the main source of energy for your body's cells,
tissues, and organs. Glucose can be used immediately or stored in
the liver and muscles for later use.
Why does carbohydrates important to our body?
 Carbohydrates are essential for a well-balanced diet and healthy
body. They are the body’s preferred energy source and fuel vital
organs – including the brain, central nervous system and kidneys.
Carbohydrate is also an important energy source during exercise.
The digestive system breaks down carbohydrates into glucose
and the pancreas secretes a hormone called insulin to help
glucose move from blood into the cells.
