PhotoPeach.com allows teachers to create slideshows with any jpeg image.  This site is FREE but it does require you to create an account.  Royalty-free music is already available on this site to accompany any slideshow you may want to create, but you can also upload your own.  You have the capability to embed these slideshows in a blog, class wiki, or in a GoogleEarth virtual tour.

Possible educational applications would be:

• Social Studies
  • Learning about a specific region, i.e. Egypt
    • Students could be assigned a certain geographic area of Egypt and pull together a slideshow.
    • Then, students could embed their slideshow into a GoogleEarth virtual tour of the region where the class could view their work as a whole to learn about this region.
  • Learning about people
    • Students could work on slide shows that focus on the culture of each area as the school year progresses to create almost an e-portfolio of knowledge gained.
• Language Arts
  • Virtual Field Trips
    • This might help bring a novel to life when discussing the setting or background history on a particular author.
    • Use this is combination with GoogleEarth so students may view the slideshow when clicking on a particular destination.
• Science
  • Biomes
    • Students may create slideshows of various animals, plants, and/or tourist attractions within specific cities/countries in their biome.

The pros to using this web 2.0 technology is that it can create easy slideshows with music that would engage the students.
The deltas to using this web 2.0 technology is that one must have an account to use it, so the teacher might create a general account for all to use or specific accounts for students.
