I’m Ken Kuwako, the Science Trainer. Every day is an experiment! “The moment you flip the switch, the light bulb turns on.” It seems like the most ordinary thing in the world, but behind that simple event lies one of the most elegant principles in physics: Ohm’s Law. Yet when students actually perform the experiment, […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. When you hear the word “capacitor,” what comes to mind? Most people vaguely know that it’s a component that stores electricity. But far fewer have ever seen what’s actually happening inside one. This time, I used a simulation tool called GeoGebra to visualize the […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. Here are two tuning forks placed face-to-face. Strike just one of them, then immediately stop its sound by touching it with your hand. The room should be silent. Yet somehow, you can still hear a tone ringing out. Behind this curious little phenomenon lies […]

I’m Ken Kuwako, the Science Trainer. Every day is an experiment. While walking through a park on a morning just after the rain, I noticed tiny droplets sparkling on the leaves. Curious, I leaned in for a closer look—and was amazed to find that the delicate patterns of the leaf were magnified with surprising clarity. […]

I’m Ken Kuwako, the Science Trainer. Every day is an experiment! Have you ever made a wine glass sing with just a single finger? It’s a surprisingly magical experience—the glass suddenly resonates like a musical instrument in an orchestra. Watch the Video First If you lightly wet your finger and gently rub it around the […]
