I’m Ken Kuwako, your Science Trainer. Every day is an experiment! If I asked you, “Which part of a strawberry are you actually eating?” most of you would probably point to that sweet, juicy red part. But what if I told you that, from a botanical perspective, that part isn’t actually the fruit at all? […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment! When you hear the number 4.6 billion years, can you actually wrap your head around how long that is? It’s a scale so massive that it’s hard to feel any real connection to it. But if we represent the history of Earth—from its birth […]

I’m Ken Kuwako, your science trainer. Every day is an experiment! I recently spotted a fascinating “Spiral Donation Box” at my child’s kindergarten. On a whim, I decided to toss in a coin, and let me tell you—it was way more satisfying than I expected! First, take a look at this video: Dancing Coins? The […]

Hi, I’m Ken Kuwako, your Science Trainer. To me, every single day is an experiment! We use the word “energy” all the time in our daily lives. But if someone asked you, “So, what exactly is energy?” would you know how to answer? Science textbooks usually define it as “the capacity to do work.” While […]

In the world of “Alternating Current” (AC), voltage and current dance together in a mysterious, rhythmic chase. Have you ever felt your head spin during a science class […]
