Have you seen the Symphony of Science website? It is awesome! Science and music combine to offer scientific knowledge in a novel way via music clips and re-mixed scientists.
My favorite so far is We Are Star Dust. The tune is catchy. I'm humming it now. It's also a great tool for teachers to jazz up chemistry, biology and physics lessons.
In addition, the Symphony of Science project offers presentations on dinosaurs, Mars, space, reality, ancient/native peoples, and the environment among others.
