Purpose
To introduce students to different soil particles and to demonstrate how they play a role in filtering and storing the Earth’s water. Students will come to understand infiltration and porosity.
Key Messages
- Soil acts as a natural filter for our groundwater
- Soil porosity refers to the amount of pore, or open space, between soil particles
- it is the amount of space between soil particles
- the shape and arrangement of soil particles help determine porosity
- Soil porosity is important
- it contains groundwater that most of us depend on for drinking water
- Infiltration, the movement of groundwater, occurs in these spaces
- some precipitation infiltrates into the surface of soil and rock
