Lesson Plan of Life Cycles of Butterfly

General Science Grade IV

Students’ Learning Outcomes

·         Draw and label key stages in the life cycle of a Butterfly.

Information for Teachers

·         A living organism passes through a series of changes from its birth to the time it produces its   next generation. This series of changes is called the life cycle of organism.

·         In many animals like frog, butterfly etc. the eggs don’t hatch directly into young ones. First, the egg hatches into larva and then the larva grows into new animal

·         The female butterfly lays a tiny egg on the underside of a leaf. The egg hatches into a worm-like larva, called caterpillar. The caterpillar grows and encloses itself in a hard structure. This stage is called pupa. The structures of adult butterfly are formed inside pupa. After that, the butterfly comes out of the hard structure of pupa.

Material / Resources

Pictures of egg, Chick and hen, posters / pictures of the life cycle stages of frog, butterfly, textbook

Worm up Activity

·         Show the pictures of egg, chick and hen (if available) or otherwise write the names (egg, chick and hen) on the board.

·         Ask students to point out the sequence of stages present in these pictures.  

·         Ask, “Can you describe the stages of your life”? Guide students to compare the above mentioned stages with the stages of their own lives i.e. toddler, teenager and adult.

·         Discuss the term “life cycle” with the students

Development

Activity 1

·         Ask the students: What you know about butterflies? Have you ever seen and touched them?

·         Explain them the life cycle of butterfly: it starts from egg, then larva forms, larva changes to pupa and finally a beautiful butterfly comes out from pupa.

·         Prepare cards with LARVA, BUTTERFLY, PUPA, EGG and ask a few students to come up and put the life cycle cards in order.

Sum up / Conclusion

·          A living organism passes through a series of changes from its birth to the time it produces its next generation. This series of changes is called the life cycle of organism.

·         In the life cycle of butterfly, larva is produced from eggs.

·         In the life cycle of butterfly larva changes to pupa.

Assessment

·         Ask the students to write in circles the number of the stages of butterfly’s life cycle and to write of the names of the stages.

·         Draw a line-diagram on board and ask the students to identify the life cycles and labels the mentioned stages. Ask them to draw the missing stages, too

Follow up

·         Ask the students to link the characteristics given below the diagrams of butterfly.

·         Explain the similarities and differences between the life cycle of frog and butterfly.
