Science Misconception Podcast
Since Wikispaces is closing, this site will be moving to
Thanks for listening all these years!

Here, you can download my Podcast series. You may listen to these podcasts on your computer, mp3 player, iPod, or on a phone. © 2008*

The first series is on science misconceptions. These misconceptions are pervasive amongst students and many block students from learning the correct explanation for the concept. The collection will grow so check back frequently. For great videos about science misconceptions, go to and view the two series, A Private Universe and Minds of Our Own.

If you have ideas for misconceptions that are not listed here, please email them to MICHAEL HORTON.
