BODY SYSTEMS RESCUE — SLS INTERACTIVE

Learning idea
A human body has different systems: digestive, respiratory, circulatory, skeletal and muscular. Learners identify the system and a relevant part from real-life scenarios.

Scoring
10 missions × 2 marks = 20 marks.
1 mark: correct human system.
1 mark: correct body part.
The visible score and xAPI payload are both derived from the same evidence array.

SLS / xAPI
The activity works offline with no external dependencies. On completion it calls window.storeState(payload) when that function is supplied by the SLS xAPI integration layer. If the function is absent, the learning interaction continues normally.
The completion payload includes score, max, scaled score, item-level evidence, misconception codes, compact teacher feedback, teaching moves, elapsed time and a bounded semantic event log.

Teacher evidence
Open “Teacher view” below the game to see item-level evidence and suggested teaching moves. The useful summary is also included in the payload feedback field.

Accessibility
Keyboard/touch/mouse controls, >=44px targets, visible focus, no drag-only interaction, no colour-only correctness cue, reduced-motion support, responsive layout.
