You have questions and A Moment of Science has answers. Short science videos and audio science podcasts provide the scientific story behind some of life\'s most perplexing mysteries. There\'s no need to be blinded by science. Explore it, have fun with it, but most of all learn from it.

I like that it&#39;s only two minutes a day. It&#39;s a quick tidbit and a dose of science. It&#39;s spoken in layman terms and is a great way to expose younger kids to science and research while showcasing the wide breadth that science envelops.
