Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

A table is provided that shows the percentages from each source and amounts needed if Earth’s real water total is scaled down 500 mL. Step-by-step instructions are included with photos. Activity guide includes a “What’s going on?” explanation and relevant connections to the uses of freshwater. Materials List:
