Students are given two options with their projects. The first choice is to create dioramas of three biomes. They then have to give a presentation about the biomes that is visually recorded. Here is an excellent example from last year of Macy's project.
The second choice is to represent the biomes using cut construction paper. The projects will be photographed and uploaded to Voicethread, where the students then narrated the pictures. Here is Keith's example from the project last year.
Here is the link to the Biome Project 2009 instructions. If you would like your class to participate, leave a comment with contact information, tweet me, or email me at firstname.lastname@example.org. Our last day of school is May 22, so if you would like to be involved please contact me soon.
