SOGWaM was developed as a teaching tool for introductory geology, hydrology, and groundwater courses. This Word Doc contains a sample exercise I have used in my class. It should work well on Windows/Android/IOS tablets and also on laptop and desktop machines.
SOGWaM, a Simple Online Groundwater Model, was developed during my Postdoc a Syracuse University. We presented it at AGU 2018:
Teaching hydrogeology with a Simple Online Groundwater Model (SOGWaM)

It may be run directly from Github, and may work better at that location: https://cjrusson.github.io/SOGWaM/
