I’m Ken Kuwako, your Science Trainer. Every day is an experiment! The other day, at Mine Park in Gunma Prefecture, I finally managed to catch an Oniyanma, often called “the king of Japanese dragonflies”! With a body nearly 10 cm long, this giant dragonfly is an incredible sight as it zips around right in front […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. Have you ever seen news footage of a supposedly sturdy building tilting after an earthquake, or manholes suddenly popping up out of the ground? The culprit may be a phenomenon called “soil liquefaction,” in which the ground behaves almost like a liquid. This time, […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. A clear liquid suddenly transforms into a sparkling mirror before your eyes. Have you ever seen anything that looks quite so magical? The world of science is full of beautiful experiments that seem almost like alchemy. One of the most spectacular examples is the […]

You can explain, “Light can split into lots of different colors,” but wouldn’t it be much more exciting to actually show them the phenomenon? As […]
