I just finished working on a project about crayfish with third grade teachers at one of my schools. The scientists in the classroom have been observing crayfish while studying in their structures of life unit. We decided to video the crayfish and create a movie using Adobe Photo Elements. After we made the video we created a blog at edublogs (http://grade3bes.edublogs.org) to display the video and ask for comments. Not all teachers have the crayfish in their classrooms, so this gives others the opportunity. After we posted it on our blog we added some links about crayfish and asked for viewers to comment on their experience with crayfish or their observations.. We knew other schools in our district have done or will be doing this unit with the crayfish. We also added a ClustrMap to show where people are visiting our site from throughout the world.
