✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The activity significantly contributed to student learning, the development of communication skills, and the strengthening of the university's social role, while also fostering scientific curiosity among participants.

C2weakest assumption

That immediate questionnaire responses from 52 visitors reliably capture meaningful, lasting changes in learning or interest without controls, follow-up measures, or checks for response bias.

C3one line summary

Physics education students ran a public-square demonstration of low-cost experiments, with post-event questionnaires from 52 visitors indicating gains in student skills and public curiosity.
