I'm planning to bring my twirling to school, too... but in a different context.
I am currently a Master's student in Elementary Education at the University of Pennsylvania. I student teach a kindergarten class in a public school in West Philadelphia. In a few weeks, I will be teaching a unit I designed on making movies.
The science component of my unit will be on the princliple of "persistence of vision," which is the principle that our retinas hold an image for a fraction of a second. That is why we see a series of still images flicked before our eyes as a moving picture, and why we see twirling fire/beaming/glow poi as circles of light.
On the day that we begin our science unit, I will turn off the lights in the classroom and twirl glowsticks for my students. Then we will discuss why they saw the glowing circles.
Just thought I'd share...
