FACTS

MINOR CONCEPTS

Develops different dimensions of knowledge, attitude

and process skills on different stages in life cycle of

butterfly, through observation, discussion, lecture

method and evaluating by questioning, participating indemonstration work and group discussion.

Egg, larvae, caterpillar, pupa, cocoon, butterfly,life cycle

1. Life cycle of butterfly consists of egg, larvae,

pupa (chrysalides), butterfly (imago).

2. Butterflies lays eggs on young leaves of mulberry

plants.

3. Butterfly eggs hatch within few days to few weeks.

4. Eggs hatches and caterpillar called larva emerges out.

5. Larvae eats maximum food it can and grows in size.

6. The larvae creates a cocoon by itself ,encloses in itand remains dormant. The larvae is called chrysalides.

7. Inside the cocoon the larvae slowly transforms into

butterfly.

1. Life cycle of butterfly consists of specific stages

namely embryonic stage, larval stage, pupal stage, and

adult stage.

2. Within 5 weeks the life cycle of butterfly completes

MAJOR CONCEPT

LEARNING OUTCOME

and metamorphosis of larvae to that of butterfly occurs.

A butterfly has a life cycle that passes through stages like

embryonic, larval, pupal, and adult stage.

Enables the student to develop

factual knowledge on life cycle of butterfly through

i. recalling new terms like egg,pupa,larvae etc,

facts and concepts mentioned in content

analysis.

ii.

recognising different stages in life cycle of

butterfly

iii. explaining the stages in the life cycle of

butterfly

conceptual knowledge about different stages in

life cycle of butterfly:

i.

recalling the structures present in each stageof butterfly in the life cycle.

ii. recognising the significance of each stage in the

life cycle.

iii. explaining the different stages in the life cycle.

iv. comparing the peculiarity of each stage in the

life cycle.

procedural knowledge on structure, function of

butterfly in each stage in the life cycle through :

i. differentiating the stages involved in the life

cycle of butterfly butterfly in various stages in

the life cycle.

metacognitive knowledge on structure and

function of butterfly in each stage in the life cycle:

i. recognising different stages of the life cycle in

PRE-REQUISITES

TEACHINGLEARNING

RESOURCES

different kinds of butterfly.

ii. identifying each structure of the butterfly in

each stage of the life cycle.

scientific attitude towards:

i. knowing more and more about importance of

butterflies in pollination.

ii. creating awareness about the role of butterfly in

nature.

different process skills like:

i. observing different stages in life cycle.

ii.

differentiating each stage in the life cycle.

iii. interpreting the structure of each stage of

butterfly and its functions.

Butterflies are insects which play important role in

pollination.

CLASSROOM INTERACTION PROCEDURE PUPIL RESPONSE

INTRODUCTION :

- How many of you have gardens at home?

- What are the types of plants seen there?

- What are the different types of flowering

plants in your garden?

- Have you seen any birds or insects visit the

flowers?

- Who are the frequent visitors?

- Which insects do you see frequently?

- Do you know how butterflies maintain their

species?

- Ok today we are going to discuss about

reproduction of butterfly.

ACTIVITY-I

Students are shown a power point presentation

on the life cycle of a butterfly. Group

discussions are held based on the discussion

points.

5/12

- Life cycle of butterfly

- Four stages are depicted

- Egg is seen on the underside of

the leaf

- Mulberry leaves are seen here

- Eggs are tiny, round, soft with

fine ribs

- Egg takes few days to few weeks

to hatch

DISCUSSION POINTS

- What does the

presentation depict?

- How many stages are

de icted?

STAGE-1

- What do you see in the 1st

stage?- Which leaf is seen here?

- What is the peculiarity of

egg?

- How long does the egg

take to hatch?


6/12

- Larva(instar)

- It is long worm like with spine

hair like structures on undersurface

STAGE-2

- What is seen in this

stage?

- What is its peculiarities?

CONSOLIDATION

- Life cycle of butterfly with its 4 stages are

depicted.

- Egg is seen in the Ist stage and it is tiny,

round, soft with fine ribs present on the

underside of mulberry leaf taking few days-

weeks to hatch.

- In stage 2, caterpillar or larvae is seen. It is

long, worm like hairs on the undersuface.


7/12

- A covering called the

cocoon.

-

The caterpillar very slowly

changes into adult butterfly.

- Pupal stage

DISCUSSION POINTS

- Stage 3

- What is seen in this stage?

- What changes occur inside the

covering?

- What is the name of this stage?


8/12

- Butterfly.

- It is brightly coloured fillies freely

with help of wings, has a antennae

to suck nectar from flowers.

- Life cycle.

DISCUSSION POINTS

- Stage 4

- What is seen in this stage?

- What are the peculiarities?

- What is the name given to the

repetitive process of development

of butterfly from egg?


9/12

ACTIVITYII

- Four students are selected to play the four

stages of the life cycle of butterfly. A role play

is conducted.

CONSOLIDATION

- The 3rd

stage depicts the cocoon wherein the

caterpillar slowly changes into a butterfly. This

stage is called pupal stage.

- In Stage 4, butterfly is seen. It is brightly

coloured, flies freely with help of wings and has

3 antennae for sucking nectar from flowers.

The repetitive process of development of

butterfly from egg is called life cycle.

EGG

Hi friends, do you know who I

am? I am the egg of thebutterfly. I am round, tiny,

soft with fine ribs. I am

attached to the underside of

leaves. It takes few days-few

weeks for me to hatch.


10/12

CATERPILLAR

Hi friends, dont you want to

know who I am? I am the

caterpillar or larvae. I am

long, worm like, with spine like

hairs.

PUPA

Hello I am the pupa. I am

inside the cocoon. I chage

slowly from a caterpillar to

butterfly.


11/12

REVIEW

QUESTIONS

ACTIVITY

- How many stages are present in the life cycle ofbutterfly?

- Name the different stages?

- Explain each stage in detail with diagrams.

- Prepare a flowchart with diagrams to illustrate life cycle

of butterfly.

FOLLOWUPACTIVITY

Prepare a report on the role of butterfly in propagation of plants and the

role they play in pollination.

BUTTERFLY

Hi friends all of you

definitely know who I am. I

am colourful, can fly freely

with wings, have 2 antennae

for sucking nectar. I lay

more eggs in future.
