Science Centre AHHAA is a science centre located in Tartu, Estonia, and is currently the largest science centre in the Baltic states. AHHAA was established to promote science and technology using interactive exhibits.

A science museum is a museum devoted primarily to science. Older science museums tended to concentrate on static displays of objects related to natural history, paleontology, geology, industry and industrial machinery, etc. Modern trends in museology have broadened the range of subject matter and introduced many interactive exhibits. Modern science museums, increasingly referred to as 'science centres' or 'discovery centres', also feature technology.
