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.

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.

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.

The Candle Elevator

Using phenomena in science classroom as a means to spark inquiry is a great way to start a lesson or even a unit. Besides the easy access to the physics and science behind the phenomenon, science content can be distributed as well as scientific processes. Students not only learn about basic principles, they also learn scientific inquiry and reasoning as well as experimental skills.

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.
