I’m on a misison at the moment trying to gather as much information about Water Resources as possible for new KS3 and KS4 units. There is alot of great information out there. On my travels I have found the Wateraid site great, especially the fre video download that can be found here. The site also has excellent games and teaching resources aimed at all Key Stages.
When I get home tonight I plan to create a list of online water resource sites, and hope to get the new learning material here soon! That is if I surviev the extra whole staff meeting tonight!
