Where there’s smoke
This Scootle resource allows students to examine on both a macro and molecular scale the effects of adding and removing the radioactive element of a smoke detector, as well as the impact smoke has on the detector's operation. The initial task asks students to write a short description of how the smoke detector works. The challenge section (at the bottom of the page) asks more detailed questions and would make a good homework or holiday assignment.
