Glowing in the Dark

Glowing in the Dark | Science Fair Projects | STEM Projects
Ever been curious about how to make glow-in-the-dark stickers glowing longer? In this project, you'll explore the science behind phosphorescence and how different types of lamps affect how long the glow lasts.


The hypothesis is that the lamp that produces more ultraviolet light will make the glow last longer.

Method & Materials

You will use lamps of different wavelengths of light and measure the time it takes for the glow-in-the-dark stickers to stop glowing.
You will need 3 glow-in-the-dark stickers, 1 infrared lamp, 1 incandescent lamp, 1 fluorescent lamp, 1 ultraviolet lamp, 1 stopwatch, and 1 meter-long ruler.


The results showed that the glow-in-the-dark stickers continued glowing the brightest after absorbing light from the ultraviolet lamp, and stopped glowing the fastest after the infrared lamp.

Why do this project?

This science project is interesting because it explores the science behind phosphorescence and how different types of lamps affect the length of time the glow lasts.

Also Consider

Consider using a luxmeter to measure the brightness of the stickers, or using different types of phosphorescent material, such as glow-in-the-dark toys or plastic stars.
