What Trickles Down?

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles. They will also be introduced to the basic concepts of building design, landscape architecture, and environmental pollutant transport. As an extension activity, learners will discuss the importance of proper drainage and urban design issues in sensitive environments such as coastal areas.
