UNIT TEN:
ZOOLOGY: VERTEBRATE AND INVERTEBRATE ANIMALS
This unit introduces students to the
major characteristics of vertebrate and invertebrate animals. There are several different phyla listed
under this topic. This unit begins with simple invertebrates such as the
sponges and continues through to complex vertebrates such as mammals. As
students explore the increasing complexity of the animal kingdom, a greater
appreciation for the complexity of humans is gained.
This unit is structured as a survey
of the animal kingdom due to the plethora of information. In the first portion of the unit, students
will examine the different invertebrates.
Students begin with sponges and continue to examine more complex
invertebrates such as worms, mollusks and arthropods.
Vertebrates or animals with
backbones will be considered in the second portion of this unit. The characteristics of the various
vertebrates will be examined. Students
will focus on the evolutionary relationships occurring between these
organisms. Students will complete the
units by comparing and contrasting the invertebrates and vertebrates based on
anatomical, physiological and behavioral characteristics.
The
following terminology will be used within this unit.
