I’m Ken Kuwako, a science trainer. Every day is an experiment. On a cold winter morning, you run a comb through your hair—only to have it puff up and refuse to settle. Ever sighed, “Static again”? That everyday annoyance actually has a lot to do with the material of your comb. And interestingly, the answer […]

This is Kuwako Ken, your science trainer. Every day is an experiment. Have you ever looked up at the sky from beneath a tank of water and felt like it was cut into a perfect circle? I had that exact experience at the penguin tank in the Sumida Aquarium. From the blue-tinted bottom of the […]

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 […]

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 […]
