Explaining energy conversion efficiency and combustion
You probably already know that I write a lot about physics experiments. But I also love science toys and today I want to talk about something more chemical than physical. Obviously, the electrochemical fuel cell cars I am talking about can (and in my opinion should) be included in physics education, because talking about energy conversion efficiency in real life and authentic settings is so valuable. The big advantage of fuel cell car toys is that they combine fun with science with real interdisciplinary science learning. See for yourselves!

If you are anything like me, you have probably prepared hard boiled eggs once, wanting to eat them the next day and put them back into the fridge. And when you’ve wanted to take them out the next day, you realized you put them right next to the raw eggs. What now? I admit, this happens more often than I would like it to be true. What a relief that I can use physics to help me find my hardboiled eggs.

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.
A variation of the lemon battery
This might be the most cliché experiment for science right after Elephant’s toothpaste. If you know how both works – congratulations, you are probably pretty nerdy. Honestly, I have seen both experiments and they are both incredibly entertaining. And since I got the Lemonade Clock for my birthday, I thought I’d show you this cool variation of the lemon battery. Especially since it does not only make a lightbulb light up but we can use the actual clock that comes with the materials of the Lemonade Clock Box.

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.

This is a tough one to figure out but goes perfectly with my last experiment, the electric motor. And with this being said, I think I already might have given you an idea on how to explain this amazing physics toy.

There is nothing more satisfying than building your own model of already functioning technology to understand the mechanisms behind it. In today’s post I’ll show you how you can build your own model of an electric engine.

Science Education profits heavily from toys like the drinking bird or fuel cell toy vehicles. Positive memories from childhood playing and natural curiousity spark children’s interest in the toy and therefore in the content, when used accordingly. Giving them time to explore hands-on is the perfect way of every science teacher into the heart of their students.
