How can I use a Blog List in MY Classroom?

In my classroom, I think having a Blog List on the same blog that I give students their homework and reading assignment updates could help with other projects for my students. If I have a list of several science blogs and tell my students to find a blog post that interests him or her, and then write a paper or give some sort of presentation on the post. Some science blog posts are experiments so a student may also be able to recreate the experiment for the rest of the class.
