This is an excellent online game for focussing on the environment and water health. The object is to build a town and keep it environmentally friendly, students need to make money via chopping down trees and raising cattle but they have to be careful to replenish and replant the trees or you will be in for an environmental diaster.
Different types of animals can be raised such as organic and luxury things can be built such as resort hotels to attract visitors.
I would suggest grade 3 up play this online game becuase it can be quite in depth
Sketch swap is a cool website where you are able to freely sketch whatever you like and after you submit your sketch someone elses bounces back. There are some small regulations such as it must be an animation and writing must be in english for moderation purposes
There is a small issue with this webiste as you dont know what sketch is going to bounce back, Im still undecided whether or not I would use it in the classroom
This webiste would be fantastic for developing kids hand eye co ordination
