What is it?

Tongjiang Lab is a collection of 54 interactive 3D lessons for high school science, covering physics (10), chemistry (25), biology (5) and geography (14). Each lesson is one self-contained HTML file of about 1 MB that opens in a browser and runs offline, so it can be used on a projector or interactive whiteboard without a network connection.

Each lesson presents a single 3D scene with a live control console, a guiding question and a step-by-step path a teacher can follow. The content is aligned with the Chinese national senior high school curriculum standards and the People's Education Press 2019 textbooks. The lesson interface is currently in Chinese.

Lessons can be opened online, downloaded individually or as a zip from Releases, or embedded in other pages via an iframe. A catalog.json file lists every lesson with its textbook location and steps. Lesson content and catalog are licensed CC BY-NC 4.0; bundled three.js code keeps its MIT license.
