I am Ken Kuwako, your science trainer. Every day is an experiment! In my last post, we used a simple umbrella bag to explore “light scattering”—the reason why the sky is blue and sunsets are red. Today, let’s dive into the secrets of fiber optics, the massive infrastructure that powers our modern world! What exactly […]

I am Ken Kuwako, your science trainer. Every day is an experiment. Back to the Special Page Have you ever noticed how an ambulance racing toward you with a high-pitched “Nee-naw!” suddenly shifts to a low, weary-sounding moan the moment it passes you? It almost feels like the ambulance lost its motivation halfway through, but […]

I am Ken Kuwako, your Science Trainer. Every day is an experiment! “What if the liquid in front of you froze instantly, like magic?” Have you ever witnessed such a breathtaking sight? Transparent water transforming into crystals at the touch of a finger, as if time itself had stopped. In our science club, we took […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment! If a set of sun-bleached animal bones were placed right in front of you, what would you feel? Would you be a little spooked, or would you find them fascinating? In reality, an animal’s skull is far more than just a relic; it is […]

I am Ken Kuwako, your Science Trainer. Every day is an experiment! Can you imagine a piece of metal, scorched jet-black, returning to its original shiny state in an instant? It might look like magic, but it is pure science. The metal we often use in the science lab, copper, is actually a brilliant performer […]
