today I recommend you these 2 games about biology from the Nobel Prize web page (even if a Nobel Peace Prize as the last one can justify war, at least they still have some funny educational games online).
This first one is about the DNA helix and the matching of the bases, I thought it could be funny to be tried with the smart board.
The second one is about the cell cycle, It is motivating way to learn the cell cycle phases and meaning.
You can visit all its medicine educational games here. Have fun and learn.
