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.
Guest post by Danny Ward
This is something new! I offered a fellow science communicator on Twitter to write a guest post for my blog and the only requirement I named him was to pick a subject of his choosing that either makes a cool experiment or has a suitable explanation for children and teens. And Danny had the perfect outreach activity in mind which he gladly explains in the following post. He studies how some micro-organisms are able infect things and how we can potentially stop them in the future. Check out his Twitter (@DannyJamesWard) or Instagram (@dannyjamesward) if you want to know more about his work!

The STEM challenge by the ICSE
ICSE – what exactly is that? It stands for International Center of STEM Education and it’s based at the University of Education in Freiburg, Germany. The ICSE is an internationally connected research center with a special focus in practice-related research and its transfer into practice. I know this, because I work at the MaSDiV project which is affiliated with the ICSE. I’ll come back to that in another post because today I want to talk about the STEM challenge, the ICSE posed on Twitter.

“Look – the paddle has a kink!”
Admittedly, I don’t have a paddle for this blog post. But I have a pen. That’s basically the same when it comes to optics. And today I did not only prepare one, but TWO experiments for exploring Snell’s Law. And they are great for younger students because they both seem like magic. And thank you to Mirjam (@fascinocean_kiel) and her great idea for this post – without her niece I wouldn’t have thought of how fascinating this phenomenon can be even for younger children.

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.

So recently, I wrote a blogpost about using video analysis to analyze the motion of a falling object. As you can probably tell, I’m fascinated by falling objects and not only do I love to analyze the movements but I also like to try new things so I prepared an experiment that is so well known and amazes me every time I see it. I hope it will fascinate you as well.

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.

Using phenomena in science classroom as a means to spark inquiry is a great way to start a lesson or even a unit. Besides the easy access to the physics and science behind the phenomenon, science content can be distributed as well as scientific processes. Students not only learn about basic principles, they also learn scientific inquiry and reasoning as well as experimental skills.

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.

You’ve probably all heard of how different liquids like water and oil have different densities and this makes them hard mixing together. But when was the last time you actually took the time to admire this effect and created something this magical with science. You can do it today and here is how:
