This paper proposes the design and implementation of a system to provide a web-based ubiquitous 3D virtual reality education environment for secondary students to help experiment freely with safety by computer simulation in physics education. To realize this system, ThreeJS, one of the famous 3D graphics libraries based on javascript, has been used to support WebGL(Web Graphic Library). Hence the system became browser independent to give flexibility for most users. It is designed to make the mouse control change the position of the camera of the 3D graphics, so that the user can observe the virtual motion in various viewpoints. In contrast to the other local PC based education systems, this web-based system is much easier for distribution and management.
