No one likes change, and it can be especially hard for children, but imagine being a caterpillar. The Swallowtail caterpillar changes its appearance four times before going through its most dramatic change - becoming a butterfly. Meet Carl the caterpillar, who greets every change with a polite, but firm, "No thank you!" As your child follows his adventures they will discover, with Carl, that while change is not always easy, it can open the way to amazing new things. A little bit of science, a little bit of fantasy, Carl the Caterpillar shares the miracle of metamorphosis and the underlying message of inner strength and the value of an encouraging word. Aligns with Common Core, NGSS, and TEKS Standards for elementary life science. Accurately portrays the life cycle of a Black Swallowtail butterfly in a charming fictional story while encouraging children to bravely face changes in their lives.
