Accoring to literature. there have been five stages in the development of science museums. The ancestor of museums is the Cabinet of Curiosities in the seventeenth century of Europe. The collections of these cabinets were shown for the pleasure of close frinds and important guests but had no public function. At second stage. science museums were derived from subject matter break-downs of cabinet collections. Their collections included the natural history specimens and instruments used in scientific research. Recently, there was a new development of the second stage science museums. Their exhibitions became more educational and began to involve visitors. Science museums were not originally founded to meet the practical needs of industry until third stage. The collections were used as teaching aids for training. At the beginning of the twentieth century, the third stage science museums gradually switched the training element of their function for that of mass education. The builtin. hands-on exhibits became more popular in these museums. Subsequently, the transmission of scientific concepts rather than the collection of objects were emphasized during the fourth stage of science museums (some of them called science center). Also, interactive exhibits have made these museums/centers more exciting. Science museums at fifth stage combined the best of the traditional science museums and modern science centers. They not only collected historical and modern artifacts, but also developed participatory exhibition to encourage learning. Traditionally, the main goal of science museums was the collection of objects in Taiwan. Most of them were classified as research institutes with no educational function. Since National Museum of Natural Science opened in 1985, science museums in Taiwan had a different vision. Museum audience became the major consideration in operating a museum. Science exhibition was also changed from hads-off to hands-on.
