All about aquifers, this site is organized and easy to follow. The activity here relies heavily on printouts. I typically don't mind making my own templates or worksheets based on printouts I can't access for activities, but this one had so many details, great questions, and intricate visuals that I would not attempt this without the printouts. If you have access to print, this is a very interactive collaborative and fun project. This activity would be best suited for more than one student to work on to instill the teamwork aspect and discussions, but this project work still be an effective learning tool for a student on their own.
