Glow Stick Experiment

Glow Stick Experiment for Kids

I found a few glow sticks rattling around one of our kitchen drawers – leftover from party goody bags, maybe? Anyway, I spent a little time surfing the ‘net for interesting things to do with glow sticks and came across a fun (and simple!) demonstration at Steve Spangler Science.

The basic idea of the experiment is to see how warm water and ice water affect the brightness of a glow stick. We kept one at room temperature for comparison, too. I wasn’t sure how dramatic the results would be, but it turned out to be really neat!

I gave the girls a simple recording sheet to fill in during our glow stick experiment. We used our big scientific words to make a hypothesis, draw and write observations, and report the results.

Happy experimenting!
