• Just Passing Through: Soil and Water Relationships with PH Testing

• Make a water filter.  (Extension: measure volume and weight of water before and after processes.)

• Make kinetic sand and create a landscape to show the effects of water on land formation and erosion.  More recipes here and here.  Augmented Reality Sandbox topographical map here.

Extensions:  Test difference soil parts by separating materials between identical bottles and timing how long it takes water to pass through.  Make a bar graph of different levels of clarity in filtered water.  Discuss lead in water and the effect in Flint, MI.
