III. PROCEDURE

TEACHER’S ACTIVITY STUDENT’S ACTIVITY

A. Preparatory Activity

1. Prayer One student will lead the classRedly…“Let us pray…In the name of the Father, and of the Son and of the Holy Spirit

2. Greetings Good Morning Tr. PreciousGood Morning Tr. BabyGood Morning Sir LouieGood Morning Sir SamGood Morning Madam CantosGood Morning Classmates

3. Warm Up SongGood morning Classmates now let us welcome our practice Teacher, Tr. Precious Tañoan

4. Drill(The teacher will flash pictures of Mitosis)What phase does the following event occur?

-Anaphase

-Metaphase

Review(The teacher will show some words)I have here words …Read it first then find the corresponding meaning on the board.

B. Lesson Proper

1. MotivationPUZZLEOK class proceed to your respective group and area.DIRECTIONS: Inside the envelop are cut pictures…Reform the pictures*After solving the puzzle…What is your idea about the picture that you come up with?

(the student will proceed to their group)(Students will start solving the puzzle.)

*It’s Digestive System

2. Presentation

Do you have any knowledge about the Digestive System?

*It breaks down food

3. Discussion

*Digestive system takes food into the body. Who can explain which means…*It breaks down food into bits, small enough to pass through the cell membrane*What do you call the process of breaking down foods? After that process the food is now put into the blood.*Do you have any idea on the different parts of Digestive System?Can you give one Redly?

The system responsible for food after we eat is Digestive System.

*Digestion

*mouth*esophagus*small and large intestine

*And now let’s follow the food as it passes the digestive system.

First food enters the mouth where it is chewed by our teeth, wets by our saliva a fluid produced by salivary gland that contains PYTALIN an enzyme that speeds up break down of starch into sugar.

From the mouth food pass through the ESOPHAGUS which transact food from the mouth to the stomach by a movement called PERISTALSIS.

*From the esophagus food enters to the STOMACH through a ring shaped muscle called CARDIAC sphincter. Peristalsis mixed food with gastric juices that will result in the churned semi liquid called CHYME. The chime leaves the stomach through pyloric sphincter and enters SMALL INTESTINE. The small intestine signal the pancreas to produce pancreatic juices and gall bladder to release bile.

Pancreatic juices aids in digestion of protein, carbohydrates and fats. Bile is produced in the liver and stored in the GALL BLADDER. It break down fats into smaller droplets.

What organ produces bile?How about the one that stores bile?After digestion absorption will take place.What are the substance that was absorbed by small intestine?

*liver*gall bladder

*Nutrients

Small intestines the remains of the digestion and absorption are now enters the LARGE INTESTINE where absorption of water occurs. The remains after water has been absorbed are now called STOOL or FECES then it will be stored in the rectum then excrete to the anus.

4. Generalization

Form your group again…Study the picture or puzzle that you’ve solve earlier. Trace the flow of food in the Digestive System and give its importance then discuss it in front.The leader will be the one to discuss.

Students will proceed to their group…Discuss the process with their group matesPresent the flow of Digestive System in front

5. Application

Identify the organ that is being described then point the specific organ on the chart.

6. Evaluation

Identification: Identify the following statement. Write your answer on your paper.1. It is the enzyme that is

present in our saliva.2. It produces the bile.3. It stores the bile.4. It is the remains of

Digestion after absorption of water.

5. It is the absorption of water takes place.

IV. Agreement

Make a research about the different Digestive disorders.Write it your assignment notebook.
