Exploring Snell’s Law

“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.

Hair and Walls and Static Electricity

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.

Optics on surface waves – Caustics in the deep blue sea

On my trip to Cyprus for our project meeting, we got the chance to make a trip to the sear and network with members of a different project while spending some time on a boat. I noticed some very interesting and fascinating patterns on the sandy floor beneath and besides feeling the urge of jumping in and enjoying the sea, I obviously almost instantly started thinking about the physics behind the phenomenon. And realized once more how much awe the physics behind nature inspires in me.

Exploring the Optics of everyday gadgets

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.

Mental Health and Social Media Use

Recently, I teamed up with Charles from Clearvue Health because he is genuinely great at visualizing medical data and I wanted to research the link between social media and mental health. He provided me some amazing visualizations which I would gladly share with you! And check out his awesome blog or his Instagram (@clearvuehealth)!

The magic of falling objects

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.
