This grant provides three years of support for the production and distribution of Science Friday, the only regular weekly show on public radio devoted to all things science. Hosted by Ira Flatow and reaching a weekly audience of some two million through radio, streaming, social media, and the web, Science Friday is a uniquely powerful platform for advancing the public understanding of science. Supported activities over the grant period include production and distribution of 150 radio segments for broadcast; 12 to 18 digital videos; 36 digital pieces in the popular SciCandy series on photography; continued production of the biweekly Science Friday newsletter, Science Diction; the hosting of three live events in the “Science Goes to the Movies” series; and continuation of the Sci Arts Book Club. Additional grant funds support outreach and engagement activities to publicize Science Friday content and broaden its audience.
