I’m Ken Kuwako, your Science Trainer. Every day is an experiment. Have you ever actually seen the “essence” of light? In movies and anime, you often see brilliant laser beams cutting through the darkness. However, the strange truth is that in the real world, light itself is invisible to our eyes unless it hits something. […]

Science Trainer Ken Kuwako here. Every day is an experiment. Have you ever experienced that ringing in your ears or that feeling of being squeezed when you dive deep into a pool? That’s the force of water pushing against an object—what we call “water pressure.” But since this force is invisible, it’s surprisingly hard to […]

Hello, I’m Ken Kuwako, your science trainer. Every day is an experiment. Ever wondered what the shape of invisible “sound” looks like? You might picture pricey gear in a science lab, but the truth is, you can pull off surprisingly professional experiments using simple, everyday items. Today, we’re diving into the “standing wave” (teijou-ha) experiment, […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. Have you ever listened closely to the “Tock-tock-tock…” sound as you pour boiling water from a kettle into a thermos? That simple, everyday sound actually hides a scientific mystery about “sound” that you learn in middle school science. Today, I’ll be talking about the […]

Hi, I’m Ken Kuwako, Science Trainer. Every day is an experiment. “Teacher, why does Japan have so many earthquakes?” When covering changes in the Earth’s crust in a science class, have you ever been asked such a simple yet profound question by a student? When we hear about an earthquake on the news—”the epicenter was […]
