This presentation from Hippocampus introduces the concept of biodiversity via a series of narrated animations. The material is broken down into five sections: Animal Fundamentals, Body Plans, Protostomes and Deuterostomes and a conclusion. Students will learn both how species are different from one another and the common bonds all living things share. Students may choose to skip between sections, or explore other related concepts on the biology portion of the Hippocampus site.

Students work in pairs to compare five aspects of an organism that reproduces sexually with one that reproduces asexually. A variety of organisms are profiled including sand scorpions, red kangaroos, and meadow garlic. As a class, students share their comparisons and generate a list of general characteristics for each mode of reproduction, and discuss the advantages and disadvantages of both. References are included for information on reproduction of various organisms.
