Ultraviolet Radiation and Yeast: Radiation Biology

In this web seminar, attendees were introduced to a radiation biology lab. They found out how to engage students with an experiment measuring how sunscreen protects live yeast cells from harmful UV radiation. Educators learned about NASA’s work to protect astronauts from radiation by studying model organisms in space. Seminar participants discovered strategies for implementing this hands-on lesson that brings the real world connection between science and education into the classroom.


This web seminar is part of a series of electronic professional development experiences sponsored by the NASA Explorer Schools (NES) project. NASA Explorer Schools invests in science, technology, engineering, and mathematics educators to inspire and engage a whole generation of future scientists, engineers and technicians that NASA needs to continue our journey. NES gives educators of grades 4-12 free access to NASA’s people, missions, research, and facilities. We take the work out of searching through thousands of materials on the NASA website and provide a comprehensive set of teaching materials for dozens of STEM concepts.
