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.
