Past Projects

Seven students worked with four professors on Physics and Astronomy projects. Two other students worked on inter-disciplinary projects with Biology and Physics professors.

Student summer research fellows at Calvin participate in the annual summer research poster fair, held in October. They also prepare a synopsis (a one page summary) of their research experience, providing relevant background as well as a statement of the problem, describing the research methods, giving any results to date and indicating how the research benefitted them personally.
