Children's Discovery Museum of San Jose is located on Woz Way in downtown San Jose, California. Woz Way is named after Steve Wozniak, co-founder of Apple Computer, whose nickname is "Woz," and who was the single largest private donor during the original capital campaign that funded the Museum. Children's Discovery Museum of San Jose has been ranked by Child Magazine as one of the top 10 children’s museums in the U.S. and ranked by the London Observer as one of the top 5 science centers in the world. The Museum opened its doors in 1990, and over 6 million visitors have attended. The Museum builds and displays interactive exhibits that they believe respond to children's diverse educational needs. The 52,000-square-foot purple building was designed by Mexico City-based architect Ricardo Legorreta. The Museum’s signature programs such as BioSITE and Discovery Youth encompass the broad themes of community, connections and creativity. These programs are intended to provide facilitated, focused, and sustained learning. The Museum’s goal is to create interactive exhibits that invite self-directed, open-ended explorations. In a redevelopment plan released in November 2008, the city of San José has stated its intentions to put forth five million dollars in funds, which will allow the museum to expand by 2013. Plans are to add a new baby mammoth exhibit.
