54 free interactive 3D science lessons — open them in any browser
A set of 54 free interactive 3D lessons for physics, chemistry, biology and geography: download one file, open it in a browser — no server or internet needed.
Each lesson is a single web page (HTML file) with a 3D scene you step through like controllable slides.
When it helps
Useful as-is if you teach the exact same Chinese curriculum. Otherwise use it as a template — have an agent study one lesson's structure and build a similar one in your language and subject.
Pros
- Runs offline, no server or GPU needed — works on an ordinary laptop
- 54 ready lessons across four subjects: physics, chemistry, biology, geography
- Opens as one file in a browser — nothing to install
- Can be fed to an agent as a sample to build a similar lesson in your language
Cons
- Ready-made lessons are in Chinese only, built for the Chinese curriculum
- For Russian or English classes you'd need to translate or rewrite a lesson
How to set it up — step by step
- 1Download one lesson file (HTML, a web page) from GitHub Releases or from lab.tongjiang.app
- 2Open the downloaded file in Chrome with a double-click and see how the 3D lesson works
- 3Open your coding agent (Claude Code, Codex) inside your project folder
- 4Send the agent the text from the block below
- 5Check the resulting lesson file — open it in a browser and go through the steps
Text for your agent
Copy this and send it to your agent — Claude Code, Codex, any of them:
Download one lesson from https://github.com/smithjohn78390/tongjiang-lab (Releases, or the lab.tongjiang.app site), open it in a browser, and ask your agent to take apart how the file works, then build a similar interactive lesson on a topic and language of your choice using it as a template. Show me the file it produces.
Runs on a regular laptop — the lesson opens straight in a browser, no GPU needed.
