Tools for this Unit:

Activity Four: The Lorax

The Lorax warned the Once-ler to stop cutting down the truffula trees but the Once-ler refused to listen. As a result of his greed, the beautiful place where the trufulla trees grew, where the swomee- swans lived, where the barbaloots played and ate trufulla seeds, and where the humming fish swam became so polluted that everyone left. Using "The Lorax", this activity will focus on the first principle of Green Chemistry, that it is better to prevent waste than to treat or clean up waste after it is formed. Dr. Seuss' powerful message is for readers to be aware of their environmental issues and to create Earth friendly action globally. The Once-ler is one of the characters in the story. He tells the boy about the Lorax who was lifted away using his whisper-ma-phone for the secrets.

Read aloud the story to the students. Ask them CPQ questions and discuss their responses. Readers will understand that the environmental issues in the story are comparable to the environmental concerns of today. Explain that when we misuse our natural resources, that would cause land and water pollution. Compare and contrast why some plants and animals are in the verge of extinction, for the reason that humans are not good keepers of our environment. The Lorax warned the Once-ler to stop cutting down the truffula trees but the Once-ler refused to listen. Explain that as a result of his greed, the beautiful place where the trufulla trees grew, where the swomee-swans lived, where the barbaloots played and ate trufulla seeds, and where the humming fish swam disappeared. Create a teacher made assessment at the end the lesson and student/teacher made rubric.
