Porosity & Permeability

Grab your lab coats and get ready. Using models and real soil samples we’ll discover how soil or surface materials allow liquids to pass through them, or why they don’t.

Activity Description

This activity illustrates the relative particle sizes of clay, sand and gravel and how these affect the flow and filtration of water as it moves through the pore spaces in earth materials. Using common objects and physical experiments, students are introduced to the concepts of porosity and permeability.

This activity centre is part of the Water Science theme.
