“Don’t Lose the Light”- a Hands-on Approach to Exponential Decay
This hands-on lesson helps students understand exponential functions by using an LED circuit. LED luminosity decreases at an exponential rate as more are added in series.
As students add more lights to the circuit, they will see the brightness of the lights dim and by measuring luminosity with a simple cell phone app, the students can actually chart the decrease in luminosity and find a trend line.
