From Caterpillar to Butterfly
Written by: Deborah Heliligman
Illustrated by: Bari Weissman
Grade Level: Preschool – 5th
From the time a caterpillar first hatches, it eats so fast that it's skin can't keep up. It sheds its skin several times as it grows bigger and bigger. Finally it forms a shell around itself called a chrysalis. Nothing seems to happen for a long time. But then one day the chrysalis splits open, and a beautiful butterfly emerges. This is a magical metamorphosis!
Just like in this book a caterpillar could be brought into your classroom. It could be kept in a jar or even an aquarium tank with a netted cover. The class can observe the caterpillar each day as it eats, grows, moves, and changes. Soon the caterpillar will “disappear” into a hard shell. The students could use magnify glasses to look closely at the chrysalis. There could even be pieces of paper with drawing materials so they can illustrate their observations. One day the chrysalis will split and a beautiful butterfly will emerge. This book is a great way to introduce this process and a great guide to the mystery of what happens to a caterpillar and metamorphosis.
This is a great informational text for a classroom. This book can be used for a science lesson. The Life Science (Biology) Massachusetts Curriculum Standards for the grades PreK – 5th grade are as followed.
Massachusetts Curriculum Standards
| 1. Recognize that plants and animals have life cycles, and that life cycles vary for different living things. | · Using either live organisms or pictures/models, observe the changes in form that occur during the life cycle of a butterfly or frog. · Discuss the life cycle of a tree. | Design and build a habitat for a living organism that can be modified to meet the changing needs of the organism during its life cycle. (T/E 1.1, 1.2) |
Life Science (Biology) Grades 3rd – 5th
| 2. Recognize that plants and animals go through predictable life cycles that include birth, growth, development, reproduction, and death. | Grow plants from seed. Document the complete life cycle of the plant. Describe emergence of structures and the functions of these structures. Record changes in height over time. Graph the data. | Design and construct a habitat for a small animal (e.g., insect, butterfly, frog) that has adequate space and contains the necessities for survival. The habitat should allow for observation of the animal as it goes through the stages of its life cycle. (T/E 1.1, 1.2, 2.1, 2.2, 2.3) |
| 3. Describe the major stages that characterize the life cycle of the frog and butterfly as they go through metamorphosis. | Using either live organisms or pictures/models, observe the changes in form that occur during the life cycle of a butterfly or frog. | |
