Animals have various adaptations that allow them to live on land and have a mobile lifestyle. Each adaptation plays an important role in the organism.
Make a three dimensional model to illustrate each adaptation. Your model is a representation of each adaptation; it does not have a to be a true example. Use your imagination!
A. Body Symmetry: demonstrate the types of symmetry.
B. Cell layers: illustrate the three layers of an animal (endoderm, mesoderm, ectoderm)
C. Body Cavities: make models of the three kinds of bodies (acoelomate, pseudocoelomate, and coelomate)
D. Support Structures: demonstrate the difference between an endoskeleton and exoskeleton.
E. Body Temperature Regulation: model ectothermic and endothermic methods of maintaining body temperature.
F. Body Coverings: make models of the four basic kinds of skin coverings (skin, scales, feathers, and hair).
G. Digestive Tracts: demonstrate the two types of digestive tracts (gastrovascular cavity and one-way gut).
H. Nervous Systems: model a nerve net and cephalization.
I. Reproduction: make a model of an amniote egg. Compare it to an amphibian egg and a fish egg.
