Caterpillar to butterfly
Name: William H
Hi! We are a second grade class at Frank C. Whiteley School in Palatine, Illinois.
We are currently studying ponds and found a neat butterfly at a pond.
We would like to know what is in a cocoon that makes a caterpillar turn into a butterfly?
Please answer our question soon because we are anxious and hopeful that a scientist out
there cares about us!!!!!
You are a nice scientist for answering our question. We will send you a nice thank you
note if you answer our question.
There is nothing inside the cocoon that makes a caterpillar turn into a
butterfly. It is a chemical inside the caterpillar. This chemical is called a
hormone and cells inside the caterpillar make it. How does the caterpillar know
when to do this?? Nobody knows for sure!
