E-learning game: Blood typing

My group found this page today while doing some research on the concept of e-learning. The simulation has a decent lesson page that makes it...dare I say it?...fun to learn about the idea of blood types. Then to practice your new found knowledge, you can take part in the emergency room rescue, helping to determine which type of blood the patients need. The game has relatively basic concepts and facts about biology and just enough blood and gore to make it enjoyable for a 13 year old. Play the blood typing game here.
