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.

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.

Floating Paper Clips

Is it science or is it magic? It is probably both and this makes experiments like the floating paper clips so fascinating and fun to implement in the science classroom. You can try it yourself and have your students debate about the experiment. With a little caution they can even make paper clips float on the water themselves.

Another physics toy! The magical everturning spinning top

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.

Simple model of an electric motor

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.
