Using waterdrop art to explain optics
I am a huge fan of the art of photography. I love how some people are able to catch the perfect moment at the perfect time and place and just get it right with their camera. And sometimes, things can turn out pretty science-y. And when you think about it, it’s pretty obvious how photography is a lot of optical physics. Let me show you what I mean.

If you have been following my blog, you might know already, that I love a good hands-on experiment served with the good ol’ inquiry. These static electricity experiments I’m going to explain are just that – prompted with a question, they awe students into wanting to inquiry the nature of hair standing to all sides, balloon floating on the ceiling and maybe even waterbending with a comb. So let’s dive into the physics behind these fascinating experiments.

Who hasn’t seen the kids walking to school with their cute little warning stripes all over their jackets and backpacks. But why do gadgets like warning stripes or safety vests even light up, no matter from which direction the headlights come from? Obviously, there’s no mirror tied to the backpack or the vest but what is it? Here’s an idea on how students can explore the optics of safety vests and find out about a phenomenon called retro-reflection.

The goal of STEM subjects is not only to provide scientific knowledge but also to establish an understanding of how scientifists work, how scientific knowledge is established and why scientists use models and theories. There are so many different approaches to establish this Nature of Science knowledge in classrooms and besides historical examples or interviews with Scientists, I really enjoy having students develop their own models and theories and test them out. This can be done with a Mistery Tube, a Tube with strings that are somehow connected within.
