Ultraviolet Radiation and Yeast: Radiation Biology

This Web Seminar took place on October 3, 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 first presentation of the Ultraviolet Radiation and Yeast: Radiation Biology program. Ms. Keil talked about what students should know in advance of these lessons, which are geared toward grades 9-12. She discussed why protection from radiation was so important for NASA astronauts, then covered the different kinds of radiation and how they produce harmful effects. The remainder of the program explored the lessons about radiation and the labs focused on yeast.

Twenty-five (25) participants were present at the live Web Seminar in addition to the presenter and NSTA staff. Participating educators represented the states of California, Florida, Georgia, Kansas, Kentucky, Massachusetts, Michigan, New Jersey, Pennsylvania, Tennessee, Texas, Virginia, West Virginia and Wisconsin. In addition, one person joined the program from a country outside of the United States: 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:

  • “It has supported some of the concepts I have been working on with my students.”
  • “When I teach the effects of radiation, there is much information I can use from this seminar.”
  • “I actually teach Physics AND Biology. I see places I can integrate some of these activities in each! I am also signing up for NASA Explorer Schools to see what else I can find!”
  • “I teach quite a bit about DNA so the part about exactly how radiation damages the DNA was really helpful for me. Also of great value were the bits of trivia about how many times we could go the sun and back with our DNA. The students LOVE that kind of information!”

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