Creating an Effective Electric Eel Display for the Belle Isle Aquarium

Abstract

Science museums, zoos, and aquariums are informal learning environments in which interactive and graphic technologies can be used to engage, entertain, and educate the general public about science concepts. Hands-on electronics and graphic displays were created for the electric eel exhibit of the Belle Isle Aquarium (Detroit, MI). Electric pulses emitted by the electric eels were converted to sound and flashes of light; the frequency of the discharges was displayed on a monitor; and an interactive button enabled activation of the sound effects. The display included text about the eels and their electrical discharges. Hypothetically, audiences will interact with the displays and be entertained and informed about electric eels. Surveys were conducted before entering and after exiting the Belle Isle Aquarium, probing engagement, entertainment and education. The interactive electronic enhancements were associated with significant increases in knowledge, overall enjoyment, and amount of time spent at the electric eel exhibit. Patrons who did the survey prior to encountering the exhibit gained more from the exhibit than those who did not. A combination of social and technical enhancements may be the most effective way to have an impact on the knowledge and enjoyment of the general public.
