It's not likely the sponge in the kitchen sink ever lived in the ocean though it's possible the one in your bathtub did. Come explore the life of the primitive and peculiar animals in the interactive program Sponges.

Pop-up graphics illustrate the characteristics classifying sponges as animals as well as the qualities that make them unique. Intriguing animations show the relationships between sponge cells and how entire colonies of relate to other organisms. Soak up information about sponge anatomy and reproduction through 3-D presentations and easy to use tutorials.

Topics covered in this program include: Paths of Evolution; The Definitions of an Animal, Vertebrate, and Invertebrate; Characteristics of Sponges; Somatic Embryogenesis; Theories of Multi-Cellular Origin; External Structures; Canal Systems; Cell Types; Asexual and Sexual Reproduction; and Ecology.

Presentation
The Presentation portion of this program includes audio-narrated scenes featuring the content from the objectives.





Interactive Lessons
Students can work through different activities that directly reinforce the information learned in the Presentation.
