The podcasts featured by WGBH ranges from grades k-12. The podcasts take a subject or a question and explains it. One that I watched, for grades 9-12, was about why the moon doesn't fall. It explained that in fact the moon does fall, it's just moving at such a high speed that as gravity pulls it down it makes an actual circle, or orbit, around the earth. If it were to slow down, it would then fall on us and if it sped up, it would orbit the sun instead of the Earth. So it's just a basic balance between the moon's speed and the universe's gravitational pull.
The podcastd were very insightful because it was more visual, which is great for me because I am a heavy visual learner, and it explains the concept so simply that it is very easy to understand and grasp it. Some were actually kind of entertaining...it reminded my of my FAVORITE science show 'Bill Nye the Science Guy'!
This would be great for students that may not understand a concept maybe the way the teacher is presenting it. It could give them a different perspective on the concept that they may relate better to or understand better.
