Ultraviolet Radiation and Yeast: Radiation Biology

This Web Seminar took place on February 8, 2012, from 6:30 p.m. to 8:00 p.m. Eastern Time. The presenter was Alissa Keil, NASA Explorer Schools Coordinator at Johnson Space Center. In this Seminar, Ms. Keil talked about radiation biology and the implications for both astronauts during spaceflight and humans on Earth.

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 third presentation of the Ultraviolet Radiation and Yeast: Radiation Biology program. In the seminar, Ms. Keil discussed the types and risks of radiation, as well as its effects on ordinary people and astronauts in space. She described how NASA studies the impact of radiation on yeast DNA, then shared a lesson that centers around a similar experiment in the classroom. Ms. Keil provided information on extensions and resources, along with details on how to become a participating educator with NASA Explorer Schools.


Thirty-seven (37) participants were present at the live Web Seminar in addition to the presenter and NSTA staff. Participating educators represented the states of California, Connecticut, Florida, Illinois, Maryland, Massachusetts, Missouri, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, Texas, Utah, Virginia, and Washington. In addition, three participants joined the program from locations outside of the United States: Germany, Puerto Rico, and Turkey.


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 the program.


Here are some comments provided by the participants at the end of the Web Seminar:

  • “Fantastic detail. I am confident I will be able to lead my students through this exploration. I am going to share the archive information with my content pedagogy cohort!”
  • “I teach gifted students and I am always looking for opportunities to help them increase their knowledge in areas of interest. Many of my students are highly interested in astronomy/space.”
  • “I needed a better understanding and I got it!”
  • “I can add it to my chapters on DNA--I think it would make a great current tie-in to what we are studying.”

Thanks to the participants and the presenter for the learning opportunity, the interactions, and a job well done!
