I’m Ken Kuwako, your Science Trainer. Every day is an experiment. Have you ever heard of a “clean gas that turns into water when burned”—a substance that sounds like magic? Well, that’s hydrogen! This time, let’s dive into an exciting chemistry experiment to generate this potential fuel of the future using simple, everyday materials! Challenge […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. The Electric Human Static electricity is one of the most common phenomena we encounter in our daily lives. For example, have you ever felt a ‘crackle’ when taking off a sweater on a cold day, or a ‘zap’ when touching a doorknob? All of […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. The fizz in soda pop, the bubbles that dissolve a bath bomb—our everyday lives are full of mysterious bubbles. The hidden identity of many of these bubbles is a gas called carbon dioxide (CO 2 ​ ). Would you like to try a science […]

I’m Ken Kuwako, your Science Trainer! Every Day is an Experiment. We all know hydrogen peroxide as that common disinfectant, “Oxydol.” But did you know you can actually extract oxygen—the gas vital for our very existence—from this liquid? Today, I’m sharing a classic science experiment, often done in middle school, that uses simple, everyday materials […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment! You divide a number on your calculator and get “7.14285714…”. On a test, how many of those digits should you actually write down? In elementary and high school math, you’re usually told something like, “Round to the nearest hundredth.” But in the world of […]
