LESSON PLANPRELIMINARY DETAILSName of the teacher : Anjali R Krishnan

Name of the school : ST.Stephens H.S.S.PATHANAPURAM

Subject : Biology

Topic : Salivary glands

Class : 9

Division : E

Strength : 42

Duration : 40min.

CURRICULAR STATEMENT

Constructing different dimensions of knowledge about the concept of saliva through observation, identification, understanding and evaluating their performance through group discussion and activities.

CONTENT ANALYSIS

New terms : Mucus, salivary amylase, lysozymes.

FACTS

Saliva secreted by the salivary glands. There are three pairs of salivary glands in humans Enzymes in saliva helps in digestion.

CONCEPT.Major concept :

Saliva produces enzymes that helps digestion easier. Mucus is the component of saliva it helps conduct the food smoothly through the

Oesophagus. Salivary amylase is converts starch in to maltose. Lysozyme kills microorganism in food.

Minor concept : Salivary glands helps to secrete saliva. Enzymes in saliva helps digestion.

LEARNING OUTCOMES

Enable the pupils to develop1. Factual knowledge on the concept of saliva through

Recalling the saliva through the prerequisite Recognizing the components of saliva mucus, salivary

amylase, Lysozyme.2. Conceptual knowledge on the concept of the salivary through

Understanding the salivary glands through activity. Recognizing the position of salivary glands through picture.

3. Procedural knowledge on the concept of formation of different components of saliva.

Understanding the function of components. Executing the activity of listing the organisms on the basis of their

salivary glands process.4. Meta cognitive knowledge on the functions of the salivary glands

through Recognizing the components of a new salivary glands Executing the activity as per the instruction.

5. Scientific attitude on nutrients in their organisms living through the importance of the food habit and the digestive process.

6. Different process skills like Observation of different organisms in the given picture. Completing the given activity card as per the instruction. Communicating through presenting the group work.

PRE-REQUISITES Digestion of food start from the mouth. Both chemical and mechanical digestion takes place in

the mouth. The saliva mixes with the food to make the process of

chewing easier.TEACHER LEARNING INTERACTIONS.

CLASSROOM INTERACTION PROCEDURE. PUPIL RESPONSE.

Preparation.

How much of you have dogs in your home? Hearing the questioning some

Pupils raising the hands.

Do you gave food to pet dog? Yes.

When you being food for him. What will the first reaction? Moving his tail.

Any other behavior? It produce saliva frequently.

Yes, today we are discussing about the glands producing saliva in

Our mouth. (salivary glands) (B.B)

Activity no: 1

Teacher showing the chart containing salivary glands and explaining pupils listening carefully.

The pairs of salivary glands.

CONCEPT FORMATION

Pairs of salivary glands

Activity : 2

Teacher showing the chart that explains the table about the

Components of saliva and functions.

Teacher then ask the pupil to read each points. Teacher

then discuss it briefly. Students write it.

The components of saliva. Function.

Mucus Conduct the food smoothly through the Oesophagus.

Salivary amylase. Partially convert starch in to maltose.Lysozyme. Destroys microorganisms it any present In food.

CONCEPT FORMATION.

Components and functions of saliva.

Activity no : 3

Teacher dividing pupil in to some groups and giving the activity cards.

Then teacher ask one member of group to read it loudly.

TRUE OR FALSE

Mucus is partially converts starch in to maltose.Salivary amylase converts starch in to maltose.Lysozyme destroy microorganisms in food.Mucus conducts the food smoothly through the oesophagus.CONCEPT FORMATION. Components and functions of saliva.CLOSURE.When food reaches the mouth more saliva is secreted from theSalivary glands. The saliva is mixes with the food to make the Process of chewing easier. Besides, the enzymes present in theSaliva also helps in digestion.

FORMATIVE EVALUATION PROCEDURE.

REVIEW QUESTIONS.

1. Name of three pairs of salivary glands?2. Which are the components of saliva?3. What is the function of mucus?4. What is the function of Lysozyme?

FOLLOW UP ACTIVITY.Digestion starts in the mouth .find out the changes occurring to food in mouth and write in your science diary?Draw the picture of salivary glands?
