The Web site for the National Aquarium in Baltimore has some valuable resources for students and teachers, as well as information for those interested in visiting the museum. Several of the teachers activities can be used in classrooms that do not visit the aquarium, and the Animals section is a sizable resource of information on a number of aquatic species. A great new feature is the interactive aquagames that provide a fun way for students to test what they have learned from visiting this Web site. The site is attractive and informative, with a variety of topics that should interest a broad range of students.
