I’m Ken Kuwako, the Science Trainer. Every day is another experiment. Why Does the Current from a Capacitor Create Such a Beautiful Curve? What if you could actually watch invisible electric current as a graph in real time? That was the idea behind this experiment. This time, I used a large 1F capacitor (rated at […]

I’m Ken Kuwako, a science communicator. Every day is an experiment! Do you remember blowing into a straw filled with limewater during science class? Watching the clear liquid suddenly turn milky white felt almost like performing a magic trick. But why does simply adding carbon dioxide make the liquid cloudy? The answer is surprisingly interesting. […]

I’m Ken Kuwako, a science educator. Every day is an experiment. In this article, I’ll introduce a simple but powerful experiment that explores sound resonance using the iPhone app “AƒG – Audio Function Generator.” Students can actually experience the relationship between wavelength and frequency, then confirm it with calculations. Best of all, the equipment is […]

I’m Ken Kuwako, your science educator. Every day is an experiment. I first learned about this fascinating video, “The Wonders of Human Digestion,” from Mr. Y, and I’ve been showing it to my students every year ever since. It’s simply too good not to share. Have you ever wondered why your stomach doesn’t digest itself […]

I’m Ken Kuwako, the Science Trainer. Every day is an experiment! If a major earthquake struck right now, would your home or office building be able to withstand it? In Japan, many buildings are designed with clever engineering tricks that help protect people from powerful earthquakes. During a visit to the National Museum of Emerging […]
