The folks over at the Sun Aeon website have put together a cool simulation of the 2012 Transit of Venus. which takes place on 5-6 June. It’s a neat way to demonstrate what’s taking place when Venus passes in front of the Sun in ths very rare astronomical event.

You can even get an embed code to host the model on your own school website or learning platform.
