Abstract
To help students to understand the knowledge about air pressure is one of important part of middle school physical education. Air cannot be seen directly. People designed many interesting experiments to show it. The most popular experiment is “fire rocket experiment”. The difficulty for many students is how to make the rocket fly the most distance by optimizing the launch conditions. This article designs a virtual emulator basing on 3D modeling and virtual reality technology to help students to research the optimization task. Through using the emulator, students do much more preparation for the real experiment and understand the knowledge better and get the special experience.
