I’m Ken Kuwako, your science trainer. Every day is an experiment! A few drops of liquid, and a stationary propeller suddenly springs to life, spinning with incredible energy. It feels like magic, but this is the very foundation of the “battery”—a discovery by Italian physicist Alessandro Volta in the late 18th century that forever changed […]

I’m Ken Kuwako, your science trainer. Every day is an experiment! In 9th-grade science, there is a particular unit where many students struggle, yet simultaneously find themselves captivated. That unit is “How Batteries Work.” We use smartphones and remote controls every day without a second thought. We know they run on batteries, but if someone […]

I’m Ken Kuwako, your science trainer. Every day is an experiment! Take a look at the red cabbage in your local grocery store. It might look like just another vegetable, but did you know it’s actually hiding a secret source of magic ink? Today, I’m going to show you how to use this humble cabbage […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment! Nothing beats the thrill of watching colorful fireworks light up the summer night sky. But today, I want to show you a different kind of firework—one that doesn’t soar into the clouds, but instead wriggles and grows right out of the ground. It’s a […]

I am Ken Kuwako, your Science Trainer. Life is one big experiment! The invisible world of electricity and magnetism is a tricky one. Trying to take these concepts off the flat pages of a textbook and visualize them in 3D is a challenge even for adults. For 8th-grade science students, things get serious when we […]
