I’m Ken Kuwako, the Science Trainer. Every day is an experiment. Have you ever thought, “Using lots of chemicals in science experiments can’t be very good for the environment…”? Fortunately, there’s a clever solution: micro-scale experiments. In this article, we’ll use this eco-friendly approach to explore the neutralization reaction between hydrochloric acid and sodium hydroxide. […]

I’m Ken Kuwako, the Science Trainer. Every day is an experiment. Have you ever crouched down and looked up at a fish tank from below in a supermarket or an aquarium? If so, you may have unknowingly stumbled across one of light’s coolest tricks. In this article, I’ll use a video I filmed at a […]
