Pulse of the Planet” children's science challenge includes 150 radio programs which focus on the interaction between a select group of scientists and youths 8-11, who have been chosen from a nationwide Science Challenge which encourages children to submit questions and potential experiments to scientists. Project partners include a variety of businesses (e.g., sports manufacturers such as K2), media (e.g., internet social networks such as imbee.com, TIME for Kids, Dragonfly TV, and Hispanic Communications Network) and educational partnerships (e.g. Community Science Workshops and the National Science Teacher's Association.) Underserved participants will be reached through Celebra la Ciencia science outreach programs.
