This paper presents the design, development, and evaluation of a mixed-reality sandbox system for creating educational experiences in geoscience. It uses an Intel RealSense depth camera to capture real-time data from a portable sandbox, which is then visualized as a dynamic 3D terrain using Unity. Custom shaders were used in projecting the terrain back onto the physical sandbox, providing immediate visual feedback. Additionally, a VR experience was developed, allowing users to explore the terrain they shaped in an immersive environment. A user study was conducted to assess usability and engagement; participants responded positively, particularly to the water simulation effects. Feedback suggested enhancing realism further by adding more environmental textures.
