Make party lights to understand electrical circuits and switches
Course Description
This three-day activity introduces students to electrical circuits and how to use a circuit to create a light switch. Students construct electrical circuits consisting of four fundamental components—power source, load, conductor, and switch. With these circuits, students create party lights that are manually controlled or set to music they choose. Students then replace the DIY switch with a microcontroller connected to a custom Excel workbook. Here they learn the benefits of digital switching and light sequence coding. This interdisciplinary lesson places students in a real-world setting as they design a party lights for an upcoming school celebration. It leverages Excel’s powerful visualizations to engage students in understanding the basics of circuitry and the benefits of digital switching. You may invite your students to present their light sequences using Flipgrid.
