Isn't this a great way to save the hungry/learn new stuff/procrastinate?
FreeRice.com donates rice to the United Nations if you play a vocabulary quiz game and get the right answers!
I'm not quite sure what the connection is between feeding the hungry and learning difficult vocabulary (other than they are both good things), but this is just the kind of charity appeal that gets someone like me excited.
There are 50 vocabulary levels (get a word wrong? go down a level) and I am consistently dancing on the border between levels 46 and 47. They say it is rare to get above level 48, but I'm determined--and from such determination, hungry people are fed!
Evidently there are about 30,000 grains per pound of rice, and if you play this game for 10 minutes you can maybe earn 1000 grains--so the more participants, the better.
