I’m late to the Earth Day Party and I know it. However, I’m neither a biologist nor do I claim to be an expert in environmental matters so I thought about it a while longer. And I decided I want to tell you a little something I found out researching how weather impacts our mood. Just for fun.Continue reading How does the weather affect our mood?
And why should you know?
What is she doing in the lab, you ask? Isn’t that dangerous? Who let her in there? Don’t worry! I’m nowhere near a laboratory and these pictures are actually from my sister. For some reason, she became a talented scientist and is currently writing her bachelor thesis in nanoscience with a specialisation in organic chemistry. And she is doing pretty cool stuff and I only understand half of it. But I do understand the part about fluorescence and it’s not only pretty but also very useful.Continue reading What is fluorescence?
Modelling with an apple and an egg
Last Tuesday, on July 16th 2019, we had a partial lunar eclipse which was visible in Germany. Unfortunately it was too cloudy for me to see but when I was 8, there was a solar eclipse right over Germany (in 1999) and I loved the event. I didn’t quite understand how rare solar eclipses are when you don’t travel to see one. I guess I’d appreciate it so much more now. Lunar eclipses are more common but still events for themselves. And what I also love about eclipses is that there are so many ways to visualize and understand these phenomena. I’ll explain three in this post.Continue reading Lunar and Solar Eclipses
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.Continue reading Teaching about Inertia
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.
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.Continue reading Polaris and Constellations
“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.Continue reading Exploring Snell’s Law
