In this video, students sit around a poster board and state stages in the life cycles of a butterfly and then a frog, placing pictures and other elements on the board that represent each stage. [2:44]

In this lesson, students will record events and evidence from the story "Frog and Toad Are Friends" so they can use that evidence to answer comprehension questions.

During this lesson, students will sequence events in "Frog and Toad Are Friends" by Arnold Lobel, describe the problem and solution, and describe the characters.

Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Describe the important difference between the life cycle of amphibians and the life cycles of other vertebrates
Distinguish between the characteristics of Urodela, Anura, and Apoda
Describe the evolutionary history of amphibians

Contains plans for five 50-minute interdisciplinary lessons that ask students to write about math-related, informational books such as "Actual Size" (Jenkins, 2004) and "If You Hopped Like a Frog" (Schwartz, 1999). Students use books like these as models to write their own math-related books about animals. In addition to student objectives and standards, these instructional plans contains links to PDF handouts and links to sites used in the lessons as well as assessment and reflection activities.

All animals develop and grow over time. The animals in this document undergo one of the most dramatic developmental processes known, metamorphosis. See if you can place the developmental stages in their proper order.

Although they can't speak, most animals have their own way of communicating. This video segment presents examples of animal communication.
