I'm a little late so please help me catch up! Donor's Choose is a great charity that collects small donations to put toward teachers' projects. There's accountability for where the money goes and you get to pick the projects. Each year groups of science bloggers have a competition to see who can raise the most.
I've selected a few interesting projects from my home state, so please consider donating to them. See them on the sidebar or go directly to the page at: http://www.donorschoose.org/donors/viewChallenge.html?id=263580 Not your cup of tea? Then please donate to another Scientopian's projects (see where we stand on the motherboard).
