This was so fun to do around Halloween time, but would be great any time of year.With leftover glowsticks from a school dance, I wanted to show my students the cool science behind them. This was a great tie in with the scientific method and a great break after our chapter test.
We went over the steps and used the handout (below) to record parts of our experiment along the way. First, I used the big camping glowsticks and showed the 2 liquids inside. I watched a Youtube video describing the details and wore gloves and eyewear as a safety precaution and as long as we are not eating or getting it on us – we’re good.
I put the liquids in different jars then mixed them. I showed the students the glass tube that breaks and mixes the liquids together – some hypothesized that after realizing that you have to “break” and crack a glowstick to get it to work.
