Last leg of Sb/DonorsChoose drive: maximizing our impact.

It's been two weeks since we kicked off our first ever ScienceBlogs/DonorsChoose drive to raise money for math and science classrooms. In that time, 172 generous readers have donated a total of $13,685.14 and SEED has kicked in $10,000.

But there are three days left of the drive, and I know you all have some greatness left in you.

Here's the deal: Of the 19 blogs participating in this drive, only Pharyngula reached its challenge goal. This would be no big deal if we were just concerned with interblog bragging rights. But, there's more at stake here: the good people at DonorsChoose are kicking in another 10% of the funds raised for each compeleted challenge. The Pharynguloids raised $6257.51, so DonorsChoose is giving PZ $625.75 to fund more teachers' proposals.

In other words, for the last three days of the drive, we need to focus on the bloggers with challenges that are closest to completion so we can get additional money from DonorsChoose and do even more good.

Details of the strategy (plus some current stats) below the fold.

The six bloggers closest to reaching their challenge goals are:

1. Stranger Fruit (47.4%)
2. Evolgen(42.0%)
3. The World's Fair (30.4%)
4. The Questionable Authority (24.4%)
5. Terra Sigillata (17.3%)
6. Cognitive Daily (16.6%)

Let's start right of the top of that list and give till the challenges are met! Each one of these challenges that meets or exceeds its goal gets an additional contribution from DonorsChoose worth 10% of the total the challenge raises. Show DonorsChoose that we can do the math on this! (Also, don't forget that Dave and Greta at Cognitive Daily have promised their own 10% match of your contributions to their challenge. )

For those who love their stats:

1. Stranger Fruit ($132.64)
