Hernán A. Supino Graña’s scientific contributions

In this work we present a spectroscope that we have constructed for science dissemination in museums. The materials used are economical and easy to handle, allowing all attendees in the spectroscopy workshop to build, use and take home a small but useful spectroscope. We also present the steps followed to construct it and the STEM activities that are carried out in the museum to learn how to use it.
