A museum is an institution which conserves and exhibits various museum artefacts from all over the world. Museums often exchange collections in order to make them accessible to more of the world. Fascinating places such as the Natural History Museum and the Science Museum are a fantastic and educational day out for the kids. There are various museum types and specialist museum focusing on particular areas of history, art, science or general interest. A museum curator is the keeper of the cultural heritage institution (museum) which is involved with interpreting the material. To make the most of an experience it is best to have a museum guided tour.
