Cool Educational Apps

Try out these three educational apps.  I think they are really cool.  These apps are for ipods, iphones and ipads.  I don't know if Android tablets have similar apps.
molecules
NOVA Elements
iCrosss Lite

We worked with the molecules app in class today. 

This is not an app, but you should check out this virtual microscope.  Have patience with it.  Have fun.
