This paper argues that science centers are expensive to create as capi
tal projects, expensive to maintain with professional staff, and, give
n the high costs of exhibit development, expensive to change. Lacking
a fixed collection of unique artifacts with which to attract visitors,
the science center is at risk when it cannot change quickly enough to
meet the demands of its users. In the past, temporary exhibitions hav
e been used as a means of creating more frequent change. Now, however,
given the exponential increase of the availability of new electronic
media, coupled with their massive interconnection via the Internet, in
formal learning can be had at home and in other sites, rendering the s
cience center unwieldy, expensive. irrelevant, and obsolete. Threats t
o the science center cannot be lightly shrugged off, and a real transf
ormation of the institution is required. The paper concludes that the
science center, as an institution and as a building project, is doomed
to extinction as a consequence of two factors-ecology and economy. It
argues for the need to develop a new kind of institution of informal
learning in its place.
