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 […]

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 […]

This is Kuwako Lab, your science trainer. Every day is an experiment. Exploring the Balance of Forces — Experience the “Aha!” Moment Have you ever stopped to wonder why the things around you stay perfectly still? Books, desks, swings, signboards—they all just sit there as if it’s obvious. But behind the scenes, invisible forces are […]

The way we spark motivation at the start of a lesson […]
