I’m Kuwako Ken, your science trainer. Every day is an experiment. Celery from the supermarket turning into a piece of lab equipment—sounds a bit surprising, doesn’t it? A student teacher, I, asked a simple but intriguing question: “Where exactly are the xylem vessels in celery?” To find out, they carried out an experiment using red […]

I’m Kuwako Ken, your science trainer. Every day is an experiment. Have you ever held your breath while peering through a microscope, stunned by the tiny world unfolding before your eyes? Together with trainee I, we observed water fleas. Using the carefully captured images taken from various angles, I’d love to introduce just how astonishing […]

This is Kuwako Lab, your science trainer—where every day is an experiment. Have you ever wondered, “Does electricity get used up as it flows?” It’s a simple question, but one that often trips up students in science class. When current passes through a resistor or a small light bulb, does it decrease? Or does it […]

I’m Ken Kuwako, your science trainer. Every day is an experiment. Have you ever watched dry ice quietly vanish while releasing a mysterious fog? It never turns into liquid—just disappears straight into gas. It almost feels like magic. But hidden inside this “not-so-ordinary” change are fascinating laws of physics and chemistry. This time, I used […]

I’m Kuwako Ken, your science trainer. Every day is an experiment. A clear, open intersection. “Wait… is that car stopped?” — just as you think that, you suddenly realize it’s actually moving, and your heart skips a beat. Maybe you’ve even heard of accidents happening this way. This strange and slightly frightening phenomenon actually has […]
