ENGAGE (10minutes)
(Get the students’ minds focused on the topic.)
Ask two students to play the Dynamic Digestion Game(Gutsy Game).
Let them choose playing pieces and place them on the start line. Take
turns rolling the die. After rolling, move that number of spaces. The first
player to travel all the way through the digestive system to the finish line is
the winner.
Tarpapel of the human digestive
system, a piece of die, tokens or
playing piece
EXPLORE (5 minutes)
(Provide students with a common experience).
ACTIVITY: Give each student a piece of a cracker and tell them to take a
bite. Ask them not to chew or swallow the cracker; just hold it in their
mouth. Ask the following question:
1. What happen to the cracker when it was in your mouth?
2. Why did it start to get softer?
3. What did you taste?
4. Let them discuss the process of digestion
Crackers
EXPLAIN (30 minutes)
(Teach the concept. Should include interaction between teacher and students).

4. Discuss the different organs of digestive system and how these organs
help in the digestion of food. Explain the processes involve in digestive
system. Give precautionary measures to maintain healthy body.
Trivia: BORBORYGMUS is the rumbling sound in the stomach. When
you hear your stomach rumbling, it is a signal from your brain that the
stomach has begun the digestion

BREAD IN THE BAG
I. Material needed: Zip lock bag, ½ sliced bread and water.
II. Procedures:
a. Take ½ piece of bread per group
b. Obtain the zip lock bag.
c. Tear your ½ sliced of bread into smaller pieces, and place it into
the bag. What does this represent?
d. Pour smaller amount of water into the bag. What does this
represent?
e. Close the bag and squish the bread with your finger until all pieces
are really small. What does this represent?
f. Drain the liquid contents down to the sink by creating a small gap
which prevent by escaping. What does this represent?
g. Put all the content of the bag into the garbage. What does this
represent?
Generalization:
1. What are the organs of the Digestive System?
2. How the organs of the Digestive System work together?
3. What is the importance of the proper care of the organs of Digestive
System?
Water, Zip lock bag, bread
EVALUATE (15minutes)
(How will you know the students have learned the concept)?
A.Identification:
1. It is responsible for the breakdown and absorption of the nutrients
from the food.
2. The organ of complete digestion and absorption.
3. The organ that stores the fecal materials, absorbs the vitamins,
and reabsorbs the water from the undigested residue.
4. Waste or the feces is temporary stored in the rectum and it was
excreted in the_______.
5. The organ where digestion and respiration cross.
6. The food is mechanically and chemically digested.
7. A muscular tube through where the food passes from pharynx to
the stomach.
8. It stores the food and mixes the food with gastric juice.
9. The food is broken down into smaller pieces in the process of
chewing or mastication.
10. The food is acted upon the chemical subs called enzymes.
B.Label the parts of the digestive system
C.Give precautionary measures to maintain healthy body.

B. Give precautionary measures to maintain healthy body.

6. MOTIVATIONAL ACTIVITY
Dynamic Digestion Game (Gutsy Game)
Objectives:
After performing this activity, you should be able to:
1. identify the organs that make up the digestive system; and
2. describe the function of each organ.
Materials Needed:
 Tarpapel of human digestive system
 A piece of die
 Tokens or playing pieces
Procedure:
1. Find a classmate with whom you can play the board game.
2. Choose a token for you and your classmate; place the tokens on the board’s starting line.
3. Take turns rolling the die.
4. The number on the die determines how many spaces you will move your token.
5. Follow the direction-if there is any-on the space you land your token
6. The player who first makes it all the way through the digestive system and down to the finish line
wins the game.
