This is Kuwako Lab, your science trainer. Every day is an experiment. 【You can also listen to this article as a radio episode!】 “Light travels in straight lines.” Sunlight, flashlight beams… it certainly looks that way, doesn’t it? But here’s a bigger question: Is light made of particles? Or is it actually a wave? This […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment! Return to Special Page Doable with a Dime-Store Toy! The Longitudinal Wave Science Experiment that Captivates Students “You can hear sound, but have you ever seen what it actually looks like?” “We hear about ‘P-waves’ in earthquake news. They say it’s the small tremor […]

I’m Ken Kuwako, a Science Trainer. Every day is an experiment. What if the ground you’re standing on suddenly turned into a wobbly, pudding-like liquid? This is ‘Liquefaction,’ a phenomenon you hear about in earthquake news. The idea of the ground turning into a liquid sounds like something out of an sci-fi movie, but it’s […]

Static electricity is everywhere—that invisible yet definitely present mysterious force: the crackle when you take off a sweater in winter, the shock when you touch a doorknob! But did you know this static electricity has the power to manipulate water, almost like magic? […]
