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.

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.

Popsicle Stick Weave

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.

The drinking bird or how toys promote science learning

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.

Thermal Imaging Cameras

Isn‘t it amazing, how technology can show us so much more than the reality we see with our eyes? I love love love working with our thermal imaging camera! As you can see, I can combine coffee drinking and experimenting and that means fun (and, depending on the amount of caffeine maybe even fast fun).
