Ultraviolet Radiation and Yeast: Radiation Biology

This Web Seminar took place on December 13, 2011, from 6:30 p.m. to 8:00 p.m. Eastern Time. Presenting was Alissa Keil, NASA Explorer School Coordinator. In this Seminar, Ms. Keil talked about radiation biology and how people can protect themselves against the effects of harmful radiation.

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 second presentation of the Ultraviolet Radiation and Yeast: Radiation Biology program. Ms. Keil gave some background on what students would need to know for these lessons since they are designed for grades 9-12. She discussed why protection from radiation is so important for NASA astronauts, then talked about the different kinds of radiation and how they produce harmful effects. The remainder of the program was dedicated to lessons about radiation and labs experimenting with yeast.


Twenty-seven (27) participants were present at the live Web Seminar in addition to the presenter and NSTA staff. Participating educators represented the states of Connecticut, Florida, Georgia, Illinois, Louisiana, Massachusetts, Michigan, Minnesota, Missouri, New Jersey, New York, Ohio, Pennsylvania, Virginia and Wisconsin. In addition, three participants joined the program from a locations outside of the United States: Germany, Israel and Romania.


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:

  • “I teach electromagnetic spectrum in all of my classes and discuss UV radiation in terms of meteorology and space. In particular I talk about all 3 types of radiation and the use of sunscreen and the role of ozone so this is relevant to those discussions.”
  • “Very relevant for my Biology classes!”
  • “I thought this program presented a very do-able and interesting activity and teaching content for the classroom. I think student will really enjoy and benefit from it.”
  • “Experiments with yeasts are very easy for my students and safe to handle/disposal.”

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