Electricity & Circuits

Inside the case file

Trace the current to crack the case. This printable Electricity & Circuits Science Mystery turns a nonfiction science passage into a science-detective investigation for Grades 6–8 science teachers, homeschoolers, and tutors. It drops straight into an electricity, energy, or physical science unit and hooks students into reading for the evidence.

The case only cracks if students read for detail; each text-based answer rules a suspect out until one remains. Print-and-go, zero setup.

The Case

The classroom lights have gone out and no one knows why, and a line-up of suspects is waiting. The only way to crack the case is to read closely about electricity and circuits — current, voltage, and resistance, and how series and parallel circuits work — using every comprehension answer as a clue to rule a suspect out, until just one remains.

How the Science Mystery Works

As Science Detectives, students read about electricity and circuits and use each correct answer to knock out a suspect until one is left — the passage is the only way through.
