Simple tools, electrifying results...
This project combines something extremely familiar with something exceptionally novel. Participants use pencils, markers and their art skills to create a wonderful drawing on a standard piece of card stock. It gets really interesting though when we flip it over and install an electric circuit on the back that lights up their drawing. Literally.
Circuits are created using special conductive copper tape, colour-fading LEDs and a 3V coin cell battery. Students learn about the polarity of electricity and the flow of electrons around a circuit. We discuss how work is accomplished (making the lights turn on) as well as how switches work.
The batteries last for 48 hours of continuous use, so when "turned off" at night they can last for over a week. Replacement batteries are available at the dollar store.
Ontario Curriculum Intersections:
This program is best for grades 3-8.
This program can be adapted to emphasize or demonstrate learning objectives in the following broad categories:
Composition with respect to future LED placement
Subject selection to make the lights "make sense" in context
Science & Engineering
How electricity accomplishes work
The difference between DC and AC power (battery vs wall)
The mechanics of switches on/off
Conductivity and continuity for a complete circuit
Brainstorming with a group
Presentation skills for finished drawings
Listening to a complete set of instructions before starting
Sharing and retelling the process with accurate scientific words
