Many museums are engaging children in geography through new technology that can landscape the topography of a sandbox. This is a new advancement in interactive play that uses sensor and light to materialize visuals onto raw material, making it a highly advanced form of interactive play. The Lawrence Hall of Science has an exhibit called Augmented Reality Sandbox which projects different colored bands that show the varying levels of sand in the box. These bands act as indicators to the depth of the sandbox as it would if one was looking at a map with mountains. This develops and understanding to complex and abstract depth and level perception. These projections change as the children shift the sand in the box. Water can also be added, and the visual representation of stream will appear as the children add different bodies and movements of water. This is integrated into the fluidity of the sand and it teaches children how water moves across earths surfaces and its effects on the ecosystems. Through the demonstrations of valleys, mountains and plateaus children can learn about the results of rain and water conservation. As well as why conserving water is so important in relation to different environments and areas of the world.
