Earth's Water Materials

We are practically drowning in information about Earth's water!  There are a number of materials students are using to investigate the distribution of water on our planet.  

A simple demonstration shows a scale model of all water on Earth (1 L) compared to water that is usable for human use (1 mL)

Here students are using three part cards to practice identifying water features like rills, springs, and canals.
