To Do:

1. Place your hands in the sand and move it around.
2. Create different formations, such as mountains and valleys.
3. Observe how and where the virtual water flows.Note the water’s direction, speed and height.

Explanation:

Sensors detect if you made a hill or scooped a canyon.  A computer and projector overlays elevation and moving water.  Superimposing computer-generated images into our real world is called augmented reality.

Application:

Topography is the study of the Earth’s surface – high and low elevations.  It helps us understand the land’s mountains and valleys, water flow into flood plains, river deltas and watersheds, and changes over time.
