Science Friday is a great site and radio show that explores different science topics. The site has news, articles, links, resources, videos, and even lesson plans for teachers (created by the New York Hall of Science).
Topics include all areas of science, politics and science, health, environment, physics, biology and much more. You can even call into the radio show on Friday's.
It's a great resource for teachers and students to learn more about science and see some of the current events and news relating to science.
