Tongjiang Lab

Tongjiang Lab is a free, open-source educational platform offering interactive 3D science lessons for high school students. Its collection includes 54 lessons covering physics, chemistry, biology, and geography. Each lesson presents a self-contained three-dimensional environment with interactive controls and guided experiments. Teachers can follow step-by-step instructions and use guiding questions to explain scientific concepts. The simulations demonstrate topics such as chemical reactions, electrical circuits, projectile motion, and biological processes. Lessons are distributed as standalone HTML files that work offline in compatible browsers. The platform supports classroom projectors, interactive whiteboards, and embedded web content. Its curriculum follows Chinese high school standards, with the interface currently available in Chinese.
