LAS VEGAS – The EM Nevada Program shared its Operation Clean Desert learning materials with educators at the Nevada State Science Teachers Association conference held Feb. 1 at Rancho High School in Las Vegas. The free materials, including classroom activities, recount the history of the Nevada National Security Site, and discuss the science on how the public and environment are safe from the effects of the site’s historical nuclear testing. Above, Kevin Schmidt, an employee with EM Nevada Program contractor Navarro, talks to teachers about how Operation Clean Desert materials can be used in classrooms.
