Here is Big Sister's silk cocoon. After the silk worm spun its cocoon, she had to put it in the refrigerator for several weeks so the moth wouldn't mature and break out. The teacher wanted them to measure the length of the silk thread. It is one long thread! She placed it in a plastic bag and then in a pet bottle with its top cut off. She put it in the vegetable bin. She took the cocoon to school today in a box. I'll post later what they did with the cocoons.
