Ribbit's Big Splash, a multimedia CD-ROM, introduces students to various aspects of water resources in four different environments: ponds, rivers, wetlands, and gulf.  Each site contains a "story" with pedagogical content, a related educational game, a "zoom" area for exploration, school and home projects which encourage exploration beyond the classroom, and a "hot word" glossary which clarifies the meanings of new or technical words. In addition, there are interactive "facts" which explore interesting scientific phenomena such as the Gulf Coast Jubilee. The CD also contains an illustrated glossary of concepts discussed in the program. The goal of  Ribbit's Big Splash is  to make learning fun and worthwhile.
