Water We Going To Do? Floodplains And Watershed Management
How has human activity affected Earth's watersheds? An action-packed lesson plan, part of the K20 Center, examines water's ability to go with the flow regardless of what is in its path. Scholars build model watersheds, examine time-lapse...
Curated OER
Engineering Application: What Can I Build On?
Students explore how earthquakes cause structures to move and how the substrate beneath them may actually cause them to fail. They create mock buildings and place them in level tubs of various substrates. They then put each through a...
