I’m Ken Kuwako, your Science Trainer. Every day is an experiment. If someone told you, “Build a duck using six blocks,” what kind of duck would you imagine? Surprisingly, even if you gave the exact same instructions to an entire class, no two ducks would ever turn out exactly alike. This simple little “duck-building” activity […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. Here’s a question for you. If you shrank the Sun down to a 50 cm diameter balance ball, how big do you think Earth would be? A soccer ball? A ping-pong ball? …Believe it or not, the answer is just 1 mm. It would […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. Wiping up spilled water in the kitchen with a cloth, or soaking up water with a sponge after taking a bath—these everyday actions actually involve something rather surprising: water moving against gravity. Try dipping a piece of kitchen paper into a cup of tea, […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment! If a major earthquake struck right now, how would your home move and shake? When it comes to protecting buildings from earthquakes, there are three major approaches: “earthquake resistance,” “vibration control,” and “base isolation.” Of these, earthquake resistance is relatively easy to picture because […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment! Would you like to see radiation with your own eyes in the science lab? In this lesson, we’ll use a homemade cloud chamber to observe the tracks of α particles released by uraninite, a naturally radioactive mineral. Cloud chambers are popular attractions at science […]
