The Case

The local water has been polluted and no one has owned up to it, and a line-up of suspects is waiting. The only way to crack the case is to read closely about water pollution and water quality — what causes pollution, how it affects living things, and how we can protect our water — using every comprehension answer as a clue to rule a suspect out, until just one remains.

How the Reading Mystery Works
