Professional Development Seminar: Ultraviolet Radiation and Yeast: Radiation Biology Web Seminar
May 23, 2012, at 8:15 p.m. EDT
The student activity featured in this seminar demonstrates the effects of radiation on living organisms. Learn how sun-screening materials protect live yeast cells from harmful ultraviolet, or UV, radiation, countermeasures for UV radiation and discuss phenotypic changes in yeast as a result of radiation damage. Also see how you can expand the range of items tested in this lab by using different sun protection materials. Use this activity to establish a connection for your students between science and a real-world situation.
