K-12 Soil Science for Teachers including quick Powerpoints on:

• See the importance of soil porosity with Dirt Investigations.

• Make an Aquifier.

• 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.)
