I’m Ken Kuwako, your Science Trainer. Every day is an experiment. The other day, I was scheduled to accompany my students on a school trip to Tokyo Disneyland. I’ve always thought that Disneyland is a treasure trove of teaching materials, so this was the perfect opportunity. Since I was going anyway, I decided to turn […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. I took a sensor with me on two roller coasters at Tokyo Disneyland—Big Thunder Mountain and Splash Mountain. And I discovered all sorts of things that you’ll never find in a guidebook. In my previous post, I analyzed the data I collected on Splash […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment! Have you ever seen what happens when a child gently drops a long plastic spring, or Slinky, from the top of a staircase? Instead of simply tumbling down, the spring slowly works its way down the stairs, one step at a time, almost as […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. Do you know what soap is made from? Believe it or not, it starts with something as familiar as cooking oil. And even more surprisingly, the process involves the very same kind of chemical reaction that helps us clean greasy stains in our everyday […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. This time, let’s take a look at an experiment on Hooke’s law and how to carry it out. Together with your students, let’s uncover the physical laws hiding behind this simple phenomenon. In this experiment, students hang a 10 g weight from a spring […]
