Digital Evidence Lab

You investigate one fictional case through four gated phases: Seize, Preserve, Examine, Conclude.

1. Complete the current phase before the next one opens.
2. Handle evidence carefully and read each case update.
3. If you break chain of custody, it stays broken for that run.
4. At the end, a correct theory only stands if the evidence process stayed trustworthy.

Target: Grades 6–12; about 15–18 minutes.

The central lesson is that how evidence is obtained and handled affects whether a conclusion can be trusted. A student can reach a sensible theory and still weaken the case through poor process.

The case is fictional and non-violent. It does not teach methods for destroying, hiding, or fabricating evidence.
