One of the pieces of educational experiment apparatus used at The Fourth Higher School. This item is a siren (Sirene) used for acoustics education. It originally belonged to Ishikawa Prefectural Callege, the predecessor school of The Fourth Higher School. This is a device that measures the vibration frequency of objects such as tuning forks. It has a rotating disk with small holes and a fixed disk at the bottom. When air from a foot bellow is fed into it at a constant pressure via a pressure regulator, it rotates and emits a sound. This rotational speed is read using the tachometer on the top, allowing the frequency of the sound to be determined. It is also possible to find the frequency of the sound via synchronization with a tuning fork, etc. The device is also mentioned in Georg Hermann Ritter's Physics Diary of 1870. It is also described in Adolphe Ganot's physics book as a device for measuring the frequency of sound. This item was manufactured by C. Gerhardt, a chemistry experiment apparatus manufacturer based in Bonn, Germany, established in 1846.

Established in 1989 to preserve and utilize valuable materials handed down from the predecessor school when the university campus was relocated from Kanazawa Castle Site. Former teaching materials such as beautifully shaped physics experiment apparatus and mushroom moulage specimens that allow you to observe mushrooms as they were 100 years ago are fun-to-see natural museum materials in the museum's collection. The museum also holds many archive such as timetables that show the hard work of medical students 100 years ago, as well as archaeological materials excavated within the campus.
