Ultraviolet Radiation and Yeast: Radiation Biology
This Web Seminar took place on May 23, 2012 from 8:15 p.m. to 9:45 p.m. Eastern
Time. The presenter was Alissa Keil, NASA Explorer Schools
Education Specialist at NASA Johnson Space Center. In this Seminar, Ms. Keil talked
about a hands-on experiment that allows students to collect data on the effects
of radiation on yeast.
The PowerPoint, related resources from the NSTA Learning Center, and web links from
the presentation are now contained in the above resource collection. Clicking on
the collection link will place it in your Learning Center, My Library, neatly organized
under the My Resource Collections tab.
This was the fourth and final presentation of Ultraviolet Radiation and Yeast: Radiation
Biology for the 2011-2012 school year. Ms. Keil discussed NASA’s research on the
impact of radiation on astronauts’ health. She described how NASA studies yeast
in space in order to better understand the ways DNA repairs damage from radiation.
She then shared a lesson that allows students to explore these problems in the classroom.
Ms. Keil shared strategies for implementing a lab experiment that tests the effectiveness
of sunscreens in protecting yeast from UV radiation. Participants learned how to
access a variety of online resources related to the lesson, including videos.
Thirty-three (33) participants were present at the live Web Seminar in addition
to the presenter and NSTA staff. Participating educators represented the states
of Arizona, California, Connecticut, Florida, Georgia, Illinois, Indiana, Kentucky,
Missouri, New Hampshire, New York, North Carolina, Ohio, Pennsylvania, Tennessee,
Texas, Washington, and Wisconsin, as well as the District of Columbia.
Seminar participants received one of the NSTA SciGuides. A certificate
of attendance was deposited into participants' My PD Record and Certificates
area in the NSTA Learning Center for completing the evaluation form at the end of
Here are some comments provided by the participants at the end of the Web Seminar:
- “I have a better idea of how to integrate Earth Science and Biology in the same lesson.”
- “Enjoyed the videos, which means my student will too!”
- “Very useful for my new Biology class.”
- “Excellent, a lot of useable material I can use right away!”
Thanks to the participants and the presenter for the learning opportunity, the interactions,
and a job well done!
