GEMS-Net Science Mentor: Guiding Education in Math and Science Network is an initiative funded by the National Science Foundation to incorporate kit-based science instruction in the K-8 classrooms in Rhode Island schools. As a volunteer science mentor I assist in the training of the teachers in kit use and physical science concepts. I have also been involved in meetings with school administrators, classroom visits, and conferences related to the GEMS-Net project.
