I actually watched two podcasts: one on precipitation & one on solar eclipses. The precipitation podcast basically showed examples of the different kinds of precipitation. The solar eclipse podcast explained what a solar eclipse is. It also showed a diagram of the way they occur. This podcast even told you the different ways eclipses can occur, and where you have to be on earth to see it.
I think that video podcast like these would be helpful in the classroom. They provide a different way of learning for the students. This gives the students a different face to look at and a different voice to hear. They would also be useful when there are no resources to conduct scientific experiments. The students could watch the experiment being conducted on a podcast. If resources are available, the podcast could be a "heads-up" for the students so that they know what to expect. Or, the students could just follow along with the podcast.
I also think that video podcast can be used to help the students with public speaking. Students can create their own video podcast where they teach something to their classmates. Then, the student will be able to view their podcast and critique themselves. They will be learning something and working on their speaking abilities at the same time.
