Inside the case file
What makes one material carry electricity while another stops it cold? In this printable Conductors & Insulators Science Reading Mystery, Grades 4–5 students find out the way real scientists do — by reading the evidence. It's a no-lab, no-prep activity that drops straight into an electricity or energy unit.
Students read for clues, use text evidence to eliminate suspects, and close the case one answer at a time. No apps, no fuss, no prep.

The Case
Something in the building keeps shorting out, and a line-up of suspects is waiting. The only way to crack the case is to read closely about which materials let electricity flow and which stop it — conductors and insulators — using every comprehension answer as a clue to rule a suspect out, until just one remains.
How the Science Mystery Works
Students step into the role of Science Detectives, reading about conductors and insulators and knocking a suspect off the list with every text-based answer until the case is solved.
