Investigating Glow Sticks

Room 3 were interested in how glow sticks work, so today we had an investigation to see for ourselves.  First we had to find somewhere dark, and as our classroom walls are mostly windows we put blankets over the tables and crawled underneath.

 Then Miss O'Kane showed us a giant glow stick and told us that when you snap the stick the glass inside the plastic breaks, and the chemicals mix which makes the glow.

Then we each got our own glow stick and snapped them, making them glow.

It was really cool learning about glow sticks.
