I’m Ken Kuwako, the Science Trainer. Every day is an experiment. I couldn’t find the spider’s stabilimentum this time. But I did spot a pill bug curled up into a perfect little ball. It was clinging to the trunk of a tree. Have you ever seen one in a park or garden and instinctively poked […]

I’m Ken Kuwako, the Science Trainer. Every day is an experiment. Have You Ever Heard of Aquabeads? Aquabeads are colorful craft beads that stick together with nothing more than water. When you arrange the tiny beads on a special tray, spray them with water, and let them dry, their surfaces soften and fuse together to […]

I’m Ken Kuwako, the Science Trainer. Every day is another experiment. Why Does the Current from a Capacitor Create Such a Beautiful Curve? What if you could actually watch invisible electric current as a graph in real time? That was the idea behind this experiment. This time, I used a large 1F capacitor (rated at […]

I’m Ken Kuwako, a science communicator. Every day is an experiment! Do you remember blowing into a straw filled with limewater during science class? Watching the clear liquid suddenly turn milky white felt almost like performing a magic trick. But why does simply adding carbon dioxide make the liquid cloudy? The answer is surprisingly interesting. […]

I’m Ken Kuwako, a science educator. Every day is an experiment. In this article, I’ll introduce a simple but powerful experiment that explores sound resonance using the iPhone app “AƒG – Audio Function Generator.” Students can actually experience the relationship between wavelength and frequency, then confirm it with calculations. Best of all, the equipment is […]
