2.  “ Watch this video and note all the important details”

(Using video clips)3.  Di Discussion

-now you done watch the video. So what our topic is all about ?

-nice answer.(click the presentation) Everybody face at board and read the meaning of digestion.

-so, what are the major parts of

-it’s all about The digestive system teacher.

- Digestion is the mechanical and chemical breaking down of food into smaller components, to a form that can be absorbed, for instance, into a blood stream.

digestive system?

-very good. Now which come first in a digesting food?

-what the mouth do to the food?

-okay very good(click the presentation and the teacher read)The mouth where food is partly broken down by the process of chewing and by the chemical action of salivary enzymes (these enzymes are produced by the salivary glands and break down starches into smaller molecules).

-After being chewed and swallowed by the mouth, the food enters to? To what children?

-so base the video you watch, can you describe esophagus?

-(click the presentation and the teacher read) The esophagus is a long tube that runs from the mouth to the stomach which after being chewed and swallowed the food by the mouth it enters now here.

-after the food process from the mouth to the esophagus, so where the foods goes now?

-so now, what is stomach?

- mouth, esophagus, large intestine, small intestine, anus

- The process of digestion starts from the mouth teacher.

- the mouth where food is partly broken down by the process of chewing.

-(raising their hands) to the esophagus.

- The esophagus is a long tube that runs from the mouth to the stomach.

-to the stomach teacher.-stomach has a long and small intestine teacher.

-(click the presentation and the student read) okay, read the meaning of the stomach class.

-class, as what you said, that the stomach has a long/ large and small intestine, so what do you think that the food enter first?

-as you see the video, can you describe the small intestine?

-(click the presentation and the teacher read) very good!

In the small intestine - After being in the stomach, food enters the duodenum, the first part of the small intestine. It then enters the jejunum and then the ileum (the final part of the small intestine). In the small intestine, bile (produced in the liver and stored in the gall bladder), pancreatic enzymes, and other digestive enzymes produced by the inner wall of the small intestine help in the breakdown of food.

-from the mouth, esophagus, small intestine. So we can say that the food go now to the large

In the stomach - The stomach is a large, sack-like organ that churns the food and bathes it in a very strong acid (gastric acid). Food in the stomach that is partly digested and mixed with stomach acids is called chyme.

- the small intestine teacher.

-small intestine is narrow and contains 25 ft. long.

-large intestine is big tube of

intestine. Can you describe what is large intestine?

-(click the presentation and the student read) very good! Can you read the meaning of the large intestine?

-is large intestine is the last process of digesting the food?

-so what is the last process?

-very good. So what is anus?

-excellent! Now give around of applause to yourself and say “I am a genius.”

4.     G Generalization

W –I have a picture here about the digestive system. I want someone go in front and take again the whole journey of the digestive system. I want you to point out which the food come first unto the last process. And give the importance of it.

Application

the stomach teacher.

-In the large intestine - After passing through the small intestine, food passes into the large intestine. In the large intestine, some of the water and electrolytes (chemicals like sodium) are removed from the food.

-no teacher.

-anus teacher.

-anus is which the food goes out.

-(student participate)

-(group activity. Doing a presentation) I will divided you class into two groups. The first group will present how the food reacts to the acid and compare the result to the digestive system. Then, the second group will present using the two tubes that here in front then differentiate them according to the stomach.

IV.            Evaluation_______________1.It is part of the digestive system which process of breaking down the food._______________2.It is a long muscular tube that starts from the back of your throat and ends at your stomach._______________3.It is a pear-shaped organ located in the upper left side of abdomen._______________4.It completes the digestion of foods._______________5.It is a large tube where the undigested food goes.

V.            Assignment: Draw a sample digestive system of any kind of animals you want to choose.
