INNOVATIVE LESSON PLAN

Name of the teacher trainee: GAYATHRI G S Name of the institution : BNV HSS for

Girls,Thiruvallam

Name of the supervising teacher: Smt. RAJASHREE.K Class : 8 A

Subject : Biology Strength : 46

Unit : 1. Life’s mysteries in little chamber Medium : English

Lesson plan : Ingredients of cell – The Cell Organelles Date : 27/10/2015

Board : SCERT Time : 40 minutes

1

Curricular Statement : In developing Factual, Conceptual, Procedural and Metacognitive dimensions regarding cell organelles through lecture cum demonstration and brain storming and evaluated by oral questioning and checking science diary.

Content Analysis

New terms : Mitochondria, Golgi Complex, Endoplasmic reticulum, Plastid, Ribosome, Lysosome, Centrosome, Vacuole

Facts : Mitochondria are the power house of the cell. It helps in the production and storage of energy. Abundantly seen in cells of liver, brain and muscles where

energy requirement is high.

Endoplasmic reticulum conducts materials inside the cell. It provides firmness and shape to the cells hence also

called as cytoskeleton of the cell.

Ribosomes are the centre of protein synthesis in the cell. It is seen either attached to the endoplasmic reticulum or

free in the cytoplasm.

Vacuoles store water, salts, excretory materials etc. It is covered by a characteristic membrane called tonoplast. In plant cells it is large in size In animal cells it is temporary and usually small in size

Golgi Complex or Golgi Apparatus collects cell secretions like enzymes, hormones, mucous etc., in small vesicles.

Seen in plenty in glandular cells

Lysosomes contain degradative enzymes enclosed in a membrane. It is hence called suicidal bag of the animal cell.

Plastids are seen in plants.

It is responsible for activities related to making and storing food

Centrosomes are seen in animals. It is the place where cell microtubules get organized

2

Concept : Cell organelles in plants and animals

OBJECTIVES

Cognitive domain : - To understand, analyze and evaluate the roles and importance of cell organelles.

- To apply the attained knowledge regarding cell organelles to create an innovation based on it.

Psychomotor Domain : To develop Skills in making models of cell organelles.

Affective Domain : To Appreciate God for such creations.

Pre requisite : Structure of cell

Aids used : - Model showing the structure of a cell - PowerPoint showing pictures and roles of cell organelles

TEACHER ACTIVITY PUPIL RESPONSE

Introduction

Goodmorning children !

Do you all like having mixture?

What are the things you could see in a mixture..?

Very good. So all these constitute the real taste of mixture , right?

So in a cell will there be any constituent like this, which may add the real property to the cell ?

Ok. Today let us check about that, ok ?

‘’ CELL ORGANELLES ‘’ (BB)

Good morning teacher

Yes

Peanuts, Curry leaves, roasted rice flour, gram flour, split channa dal etc

Yes

Yes/No (No clear idea)

Yes

Activity 1

Teacher shows a model of the cell. Can you identify the cell oraganelles?

Consolidation

There are many number of cell organelles in a cell. It constitutes Mitochondria, Golgi Complex, Endoplasmic reticulum, Plastid, Ribosome, Lysosome, Centrosome, Vacuole .

Pupil are keenly observing the picture

No response

5


ACTIVITY 2

Do you know the roles of each organelles ?

Don’t you wish to know about it?

Ok.let’s check it.

Teacher shows a PowerPoint focusing cell organelles and its role

No

Yes

Students are keenly observing the slides.

Consolidation

Mitochondria are the power house of the cell. (BB)It helps in the production and storage of energy.Abundantly seen in cells of liver, brain and muscles where energy requirement is high.

Endoplasmic reticulum conducts materials inside the cell.(BB)

It provides firmness and shape to the cells hence also called as cytoskeleton of the cell.

Ribosomes are the centre of protein synthesis in the cell.(BB)It is seen either attached to the endoplasmic reticulum or free in the cytoplasm.

Vacuoles store water, salts, excretory materials etc.(BB)It is covered by a characteristic membrane called tonoplast.In plant cells it is large in size.In animal cells it is temporary and usually small in size

Golgi Complex or Golgi Apparatus collects cell secretions like enzymes, hormones, mucous etc., in small vesicles.(BB)

Seen in plenty in glandular cells

Lysosome contain degradative enzymes enclosed in a membrane.(BB)

It is hence called suicidal bag of the animal cell.

Plastids are seen in plants.(BB)It is responsible for activities related to making and storing food

Centrosome are seen in animals.(BB)It is the place where cell microtubules get organized.

Pupils are hearing the facts silently

ACTIVITY 3

Students, don’t you all like Cookery show?

So today I am planning to conduct a competition to find out the Master of Chef in this class. Let me see who will attain that Title. Are you ready?

Ok. You have to prepare 2 dishes, Animal cell dish and Plant cell dish. For that I shall give you a mixture of ingredients. Let me see who will prepare the dishes using correct ingredients. Shall we go?

Ok. It will be for 10 minutes and your time starts now.

Yes

Yes we are ready

Sure

8


Ingredients

Students are clearly noting the ingredients from the mixture for preparing both dishes

9


Consolidation

Teacher appreciated those who made both the dishes perfectly and found the Title winner among them. Selection was done based on less error and minimum time consumption.

Later on she consolidated the process of preparing the dishes.

Students are preparing the dishes

10


Using ingredients

Pupil listens carefully

11


Is prepared

Thus yummy animal cell is ready!Pupils are smiling

12


Using ingredients

Pupil listens carefully

13


Is prepared

Thus yummy plant cell is ready !

Hope you won’t make mistakes in preparing these dishes. Right?

Pupils are smiling

Yes

REVIEW

1. Which cell organelle is known as the power house of the cell ?

2. Which cell organelle is the centre of protein synthesis ?

3. Which cell organelle stores water, excretory materials etc ?

4. Which cell organelle conducts materials inside the cell ?

ENRICHMENT ACTIVITY

Make a model of a cell organelle , you like the most.

Draw the structure of a plant cell and animal cell representing all its cell

organelles and parts.
