An Alarming Idea: Designing Alarm Circuits by National Center for Technological Literacy
This unit helps students to apply their knowledge of electricity, circuits, conductors, and insulators as they design and construct their own alarm circuits. The science concepts of electricity/energy transfer, conductors and insulators, and complete and incomplete circuits are reinforced and students are also introduced to schematic diagrams, a symbol "language" that electrical engineers use to plan and design circuits. Through lessons and the unit's storybook, which takes place on a station (or ranch) in the Australian outback, students embark on an electricity scavenger hunt, practice drawing schematic diagrams from circuits, and finally design, create, and improve their own alarm circuits and switches to remind them when it is time to do an important chore.
