In the Classroom
This site is perfect for an interactive whiteboard or projector. Learning support students and weaker readers will benefit from the audio option. Use the information here as a springboard for other discussions, blog posts, or displays about planets possibly like Earth. Identify how technology and science has changed over the years and the natural laws that were understood prior to the discoveries. Have cooperative learning groups explore a specific section of this site and create a multimedia presentation to share with the class. Challenge groups to narrate a photo (legally permissible) using a site such as Slidestory, <a href="/single.cfm?id=16562">reviewed here</a>. To find Creative Commons images for student projects (with credit, of course), try Compfight, <a href="/single.cfm?id=10280">reviewed here</a>.
