**I AM RICE**

**A reading activity on the Digestion of Carbohydrates**By Camilo Apita Tabinas

I would like to share this method of teaching the topic on digestion of carbohydrates. This worked with my students. You may wish to try it with your students.

Time allotted and criteria for grading the students outputs are left for the teacher to decide as students may differ from class to class.

**Teaching details:**

1. the teacher discusses with the students the anatomy of digestion (including the hormones involve), the roles of enzymes, and the differences between brush border enzymes and other enzymes of digestions.

2. Group the students and let them read the article below “I am Rice” (an article I composed to make the topic a little bit softer or not to appear so technical).

3. Let each group diagram the digestion of carbohydrates based on the article they just read.

4. Let each group post their diagrams on the board side by side. Then, let the class study the diagrams posted and spot their similarities and differences.

5. Based on the comments by the students on similarities and differences of the posted diagrams, let the students decide which diagram is the closest to what the article says.

6. The teacher inserts the digestion of other carbohydrates such as disaccharide sucrose. The teacher at this point may clarify or reiterate the purpose of digestion and where it ends.

7. Finally, let each student of the class write his own revised diagram on a piece of paper ( revisions from the diagrams posted on the board).

**Activity Proper:**

**Instruction for students**:

a)Read the article " I Am Rice" below; then

b) make a diagram illustrating the steps of the digestion of starch; and

c) List the enzymes involved with their specific roles in the digestion of starch.
