With Freerice, you can do good by having fun. Answer one of the multiple-choice questions correctly — on topics such as English vocabulary, geography or chemistry — and the site's sponsors will donate 10 grains of rice to the U.N. World Food Programme. It doesn't sound like a major act of charity — but so many people answer so many questions that the site is responsible for the donation of hundreds of millions of grains of rice every month. That's enough to make a major difference for tens of thousands of hungry people in Haiti and other countries that need help.
In 2004, Salman Khan started tutoring his cousin over the Internet. In 2006, he began uploading educational videos to YouTube. And in 2009, he quit his day job as a hedge-fund manager to concentrate on Khan Academy, a sort of one-man university. Today the site offers his free lessons in thousands of highly visual 10-minute chunks. Math and science dominate, and students are the primary audience, but Khan is adding additional topics and welcomes adult learners. It's a remarkable undertaking — and with funding from Google and the Bill and Melinda Gates Foundation, it has a bright future.
