CS2
081107E23
Teacher: Chng Chye Thiam Daniel
Subject: Biology
Unit/Topic: Chapter 6 / Animal nutrition
Class Level and Stream: Sec 3P
Student Ability: Above Average
Duration: 2 periods - 60mins
Prerequisite Knowledge:
Students are able to:
1. State the 5 stages of nutrition (ingestion, digestion, absorption, assimilation, egestion) in the human digestive system.
2. Identify the main regions of the alimentary canal (mouth, oesophagus, stomach, duodenum, ileum, colon, rectum and anus) and
the associated organs (liver, gall bladder, and pancreas).
3. Describe the stages of food digestion along the alimentary canal.
a. Describe the chemical or physical digestion take place at the following parts:
b. mouth
c. oesophagus
d. stomach
e. small intestine (duodenum and ileum)
Specific Instructional Objectives:
At the end of the lesson, the students should be able to:
1.
Describe the structure of the villus and its role, including the capillaries,blood vessels and lacteals in absorption.

Ts will:
(Opening)

Show Ss the pig intestines.

Show an overview of the main concept of small
intestine and associated organs.

Ask Ss to describe the secretion of the intestinal
juice and the end products of the ileum found in
the small intstines.

Ask Ss to recall each stage of digestion and inform
Ss that we have reach the 3rd stage –Absorption.
Rationale


Recapitulation is important for
Powerpoint
students to review what was taught Slides
in the previous lesson so as to
consolidate the information To
link new concept to previous
concepts being taught.

Distributed questioning to check
for Ss understanding.

Serve to motivate Ss.

Ts will
 State the learning outcomes.

Allow Ss to know the important
key concepts and prepare them
for the lessons students what to
look out for during the lesson. It
serves as a general guideline for
them.


Explain its’ role of absorption

Questions being asked while
introducing the new concept and
linking back to previous
knowledge thus enabling Ss to
think and process the information.


- Only the simplest form of the food will be
absorbed

Ask Ss to describe Carbohydrates
(monosaccharide), Proteins(amino acids) and
Fats (fatty acids and glycerol) in its simplest
form.


Allow Ss to know the important
key concepts of the finger-liked
projection features in the small
intestine that helps absorption.


Group activity, break ice and also
serve as a macroview on how villi
look like (fingerlike projections)
Allow Ss to know the special
features of villi.
Powerpoint
Slides

Allow Ss to view the anatomy of villi and their
location at the inner cell wall of small intestine.

To explain each of the main
features that aid in absorption.

To gather responses and building
on their answers.

Keep momentum of the lessons
Identify the main features of the inner cell wall
- multiple folds
- microvilli
- one cell thick
- blood capillaries network
- lymph vessel


To explain the concept of absorption via diffusion.

Ask Ss to recall how diffusion take place (High
Concentration to low concentrationgradient.)

Ask Ss
- which part of the small intestine will have
higher concentration of nutrients? (exterior of
the villi)
- Which part will have lower concentration of

Methods/Activities
Ts will

To explain the concept of absorption via active
transport.
Ask Ss to recall how active transport take place
( Against a concentration gradient.)
Ts will

Explain the fate of the absorbed nutrients
depends on their solubility.
Rationale

To gather responses and building
on their answers.

Keep momentum of the lessons

To high light diffusion of nutrients
into either blood capillaries or
lymph vessel depends on their
solubility in water.

Eventually, Ss will know that
water soluble nutrients will diffuse
into blood capillaries and
transported to liver via Hepatic
Portal Vein.

Water insoluble nutrients will
diffuse into lymph vessel which
connect to blood circulatory
system.

To reinforce learning.

Provide Ss examples of water soluble nutrients
such as glucose, amino acid, Mineral salts,
Vitamin B,C.
Ask Ss if they know of any water insoluble
nutrients? (Fatty acid and glycerol, Vitamin
A,D,E,K)
Ts will

Ask Ss to draw the anatomy of the cross-section
of the villus and label the parts.
