Thoughts about the energy concept
Let’s talk about energy. But don’t despair, this won’t become too theoretical. I promise. All I want to do is to nudge you into the right direction of thinking about energy as a concept that can explain many things in everyday life. Because that’s all there is to it. Obviously, the last sentence isn’t true, as energy is still something worth researching. But the technicalities are not important, but how we think about it is. So let me give you an example.

The phenomenon of Thermochromism
When I was a child, I would stand in front of fair booths and try on all sorts of mood rings and adore them. The change of color fascinated me. I really wanted to purchase one and my parents didn’t let me. Oh how unfair the world seemed to me. I didn’t care that these rings weren’t worth the money, I just loved watching the colors turn.

Today, I know about the phenomenon of thermochromism and it still fascinates me. But I’ve also studied a little bit of physics and now understand the science behind the phenomenon so much better than when I was a kid. In this blog post, I’ll show you what thermochromism is, why it occurs and what we can learn about energy from it.
Interlocking popsicle sticks in a chain adds tension to the construct. When released, the release motion of the sticks looks like a wave and scatters the sticks all over the area. It’s a great game to play, since children need to practice some motorics while at the same time learning about conversion of elastic potential energy into kinetic energy.
