## 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.

## Exploring the Optics of everyday gadgets

Who hasnâ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.

## Or how does the ant survive the fall?

Mobile learning is a concept as old as time. Taking a book for learning to the park for example is one way to take learning to the mobile level. The concept of mobility as “anywhere and anytime” isn’t new. But the use of mobile devices like tables and smartphones brings it to a whole new level. And as a science teacher, I think a lot about how to integrate digital media into the classroom. Let me show you an example of how implementation could work. I’ll use the freely falling coffee filter to demonstrate air friction.

## 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.

## 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.
