All activities
24 hands-on activities, ordered by chapter. Each is meant as a ready-made double lesson — learning goal, materials, step-by-step, worksheet with solutions and an extension. About half run entirely in the browser.
M Master extension (advanced) R Reflection D Discussion
Make heart-rate variability visible — how tension changes the rhythm of your pulse.
Measure your own class chat: response times, balance of contributions, giving and taking.

Have a language model write the analyzer in four steps (vibe coding).
From word-counting to a language model: fine-tune gbert-base and catch the Leech with Sentence-BERT.
Network analysis of a real open faculty: find the queen bee by betweenness (networkx).
Recognise emotion from the face in real time (webcam, HSEmotion) — and feel the unease of it.
A memoryless model applied many times: record and plot your own emotional course.
Retrace "Your Face Mirrors Your Deepest Beliefs" — deliberately as reflection, ethically delicate.
