Ken Kuwako, Science Trainer. Every Day is an Experiment! A single sheet of paper suddenly “boings!” into the air, as if it has a life of its own. It’s the “Origami Frog,” a paper toy almost everyone has made at least once as a child. I recently made one again, this time with my own […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. The Van de Graaff Static Electricity Experiment: How Does an Empty Can Move? That sharp, painful zap! of static electricity is a common experience, especially on doorknobs in winter. But have you heard of a device called a “Van de Graaff generator”? It can […]

I’m Ken Kuwako, Science Trainer. Every day is an experiment. The “Daniell Cell” is an incredibly important topic for understanding how batteries work. However, many teachers might be struggling with the hassle of preparation or the difficulty of disposing of chemical waste, right?That’s why we’re introducing the one and only “🍔Hamburger Daniell Cell”! True to […]

I’m Ken Kuwako, a Science Trainer, and every day is an experiment. When winter rolls around, we all know that sudden “Zap!” when you touch a doorknob, or the crackling sound when you pull off a sweater. These are all the work of “static electricity,” where materials build up an electrical charge. Today, I’m going […]

But have you ever stopped to think about how batteries actually generate electricity? The truth is, anyone can easily make a battery with just two different types of metal and “a certain liquid.” […]
