EireneEduCloud — Download Packages

📀 Full offline editions — download & run from a flash disk

Copy onto a USB flash disk, open index.html in any browser, and the whole platform runs with no internet — bundled videos, audio narration, virtual labs, games, animations and quizzes.

⬇ Full Offline Edition — whole site (~98 MB) ⬇ All-lots flash-disk bundle (~87 MB)

The Full Offline Edition mirrors the online site exactly (same navigation & look). The all-lots bundle is the per-lot packages with a Start Here menu. Videos are original Eirene narrated lessons; PhET labs © University of Colorado (CC BY); Wikipedia summaries CC BY-SA.
