ScienceBlogs is helping raise funds for classroom projects in math and science.  Check out the website for the different projects sponsored by the different blogs.  Many of the schools asking for donations are in high poverty regions.  You can help sponsor a project on solar energy, get DNA model kits for a classroom, or buy board games to improve math skills.  Lots of worthwhile projects!

You can see all the projects from Donors Choose (not just the ones sponsored by the ScienceBlogs community) on their website.
